Reduce jumping, look for injury and arrange assessment for persistent pain
Open movement guidance →STOPPED JUMPINGWhy has my cat stopped jumping?A quiet route change can be an early sign of pain or weakness
Open movement guidance →BACK-LEG SHAKINGWhy does my cat’s back leg shake while standing?Use non-slip footing, record the pattern and do not provoke exercise
Open movement guidance →A head tilt, stumbling, abnormal eye movement or confusion can come from ear, toxin, injury or neurological problems. Keep the cat safely at floor level and seek prompt veterinary assessment instead of repeatedly testing balance.
Food intake, water use, urine output and body weight belong together. Record the change, keep water freely available and contact a veterinarian promptly when a cat stops eating, becomes weak or loses weight unexpectedly.
Confirm the last normal meal and call promptly for sustained refusal
Open appetite guidance →DRINKING MOREWhy is my cat drinking more than usual?Keep water available and measure the change with urine output
Open appetite guidance →WEIGHT LOSS WHILE EATINGLosing weight despite eating: why it mattersTrack food and weight because a strong appetite does not rule out disease
Open appetite guidance →Drooling, dropped food and repeated lip smacking can overlap with dental pain, nausea, swallowing trouble or exposure. Film a natural meal if safe, keep packaging after possible exposure and seek prompt care when eating or swallowing changes.
Check swallowing, possible exposure and whether saliva is new or heavy
Open mouth-sign guidance →DROPPING FOODWhy does my cat drop food while eating?Dental pain, mouth injury or texture difficulty can interrupt eating
Open mouth-sign guidance →LIP SMACKINGWhy does my cat smack their lips after eating?Separate brief grooming from repeated nausea or oral-discomfort signs
Open mouth-sign guidance →Hair loss, intense grooming and a newly greasy or divided coat can reflect parasites, allergy, pain, reduced mobility or illness. Avoid human creams and essential oils; record the change and arrange assessment when it persists, spreads or becomes sore.
Photograph the pattern and check skin, itch and flea-prevention history
Open skin guidance →OVERGROOMINGCat overgrooming: stress, itch or pain?Stress is only one possibility; itch and pain must also be considered
Open skin guidance →FUR SEPARATINGWhy does my cat’s fur separate into little sections?Grease, dandruff or reduced grooming can make coat sections more visible
Open skin guidance →One-sided discharge, squinting, cloudiness, ear pain or a head tilt can need prompt assessment. Take a clear photo, avoid leftover drops and do not probe the eye or deep ear canal while trying to identify the cause.
Compare both eyes and look for squinting, redness or cloudiness
Open eye or ear guidance →ONE EYE IN WIND OR LIGHTWhy does one cat eye water in wind or bright light?Move indoors and recognise pain or injury signs that need prompt care
Open eye or ear guidance →EAR DISCHARGECat ear discharge: what colour and smell can tell youColour and smell are clues; pain, swelling or head tilt needs assessment
Open eye or ear guidance →Sleeping more, hiding or feeling warm are not diagnoses. Check whether eating, drinking, movement, grooming, breathing and litter-box use changed too, and contact a veterinarian when the pattern is sudden, persistent or joined by weakness or pain.
Note timing, frequency, duration, appetite, water, urine, stool, breathing and behaviour. A short video can help when safe to record.
Open-mouth breathing, severe breathing effort, collapse, repeated seizures, major trauma and urinary straining with little urine need immediate triage.
Your cat’s normal baseline matters. Repeated changes, combinations of signs and deterioration provide important context.
No. It can support observation and communication, but diagnosis requires an individual veterinary assessment.
Call immediately for breathing difficulty, collapse, seizures, major trauma, suspected poisoning, severe pain or inability to urinate.

Small hard stools, repeated attempts and painful defecation may indicate constipation, but litter-box straining can also be a life-threatening urinary blockage. Confirm that normal urine is passing before assuming the problem is stool.
Read the guide →Small hard stools, repeated attempts and painful defecation may indicate constipation, but litter-box straining can also be a life-threatening urinary blockage. Confirm that normal urine is passing before assuming the problem is stool.
Bright red blood usually comes from the lower digestive tract, while black tarry stool can represent digested blood from higher in the gastrointestinal tract. Colour and amount help triage, but bleeding with weakness, pain or illness needs prompt veterinary care.
Truly black, sticky, tar-like stool can be melena—digested blood from the stomach or upper intestine—and needs prompt veterinary contact. Dark brown stool is different, but home appearance alone cannot safely rule bleeding in or out.
Mucus can coat stool when the colon is irritated, but appearance alone cannot identify the cause. Repeated mucus, diarrhoea, blood, straining, pain or illness warrants veterinary assessment and may require a fresh stool sample.
One isolated vomiting episode may be brief, but repeated vomiting is not normal. Count every episode and assess the whole cat—appetite, energy, pain, hydration and possible toxin or foreign-object exposure determine how quickly veterinary care is needed.
An occasional expelled hairball can occur, but frequent hairballs, repeated vomiting or unproductive retching should not be dismissed as normal grooming. Confirm whether hair is actually produced, reduce loose fur safely and seek veterinary advice when the pattern changes or repeats.
Regurgitation is usually a passive return of food or fluid from the oesophagus, often soon after swallowing and without the abdominal effort typical of vomiting. Repeated episodes need veterinary assessment because fast eating is only one possible cause.
Gagging and retching can resemble coughing, vomiting or regurgitation. Breathing and swallowing determine urgency: repeated unproductive episodes, suspected string, choking or any breathing difficulty needs prompt veterinary attention.
Long digging can reflect individual preference, a box that is too small, disliked litter, difficulty finding a clean area or discomfort while trying to toilet. Check what the cat actually passes—prolonged digging with straining or little urine needs prompt veterinary attention.
A cat sitting in the litter box without toileting may be seeking a familiar-smelling refuge, but the same behaviour can accompany urinary pain, constipation or repeated unsuccessful attempts. A new pattern requires close output checking and veterinary advice.
A cat that stops eating needs prompt attention because appetite loss can reflect pain, nausea or serious illness and may lead to dangerous liver complications. Confirm the last normal meal, offer familiar food without force and contact a veterinarian the same day for sustained refusal.
Repeated vomiting needs prompt veterinary assessment. Blood, severe pain, weakness, breathing change, inability to keep water down or possible toxin, string or foreign-body exposure can make it an emergency.
Difficulty breathing in a cat is an emergency. Open-mouth breathing, pronounced chest or abdominal effort, a stretched neck, blue-grey or very pale gums, collapse or inability to settle requires immediate veterinary care.
Repeated litter-box straining may be constipation or a urinary emergency. If normal urine cannot be confirmed—especially in a male cat—contact an emergency veterinarian immediately and do not wait to identify the cause at home.
Cat coughing is often mistaken for an unsuccessful hairball attempt. Record the natural episode safely and note whether anything is produced, but treat repeated coughing as a respiratory sign that needs veterinary assessment rather than automatically giving a hairball remedy.
Occasional sneezing may be minor, but repeated sneezing with nasal discharge can accompany infection, irritation, dental disease, a foreign body or another condition. Appetite and breathing determine urgency.
Cat diarrhoea may be brief or reflect parasites, infection, diet problems, toxins, foreign material or systemic illness. Frequency matters, but age, hydration, appetite, vomiting and overall condition determine how quickly veterinary care is needed.
A cat that starts limping may have a paw injury, torn claw, bite, fracture, joint pain or another painful condition. Restrict running and jumping, observe without forcing the leg and arrange veterinary assessment.
More hiding than usual can be an early sign of pain, illness, fear or conflict. Let the cat keep a safe retreat while comparing appetite, litter use, movement and social behaviour with its normal pattern.
Wind, dust or bright light may cause brief watering, but repeated tearing from one eye can signal injury, pain or eye disease. Squinting makes prompt assessment more important.
One sneeze after drinking may follow a splash or awkward bowl angle. Frequent sneezing, discharge, blood, noisy breathing or reduced appetite suggests more than a drinking habit.
Brief lip licking after eating may be normal mouth cleaning. Repeated smacking can accompany nausea, dental pain, an oral foreign object or swallowing discomfort.
Persistent fishy or foul breath is not normalised by fish-flavoured food alone. Dental disease is common, while oral, digestive and systemic illness can also change breath.
A senior cat missing the litter box needs easier access and a veterinary assessment. Pain, urgency, constipation, sensory change and cognitive problems can all contribute.
A sleeping cat may rest the forehead lightly against a wall, but persistent forceful head pressing while awake can signal a neurological emergency. State of consciousness and the wider signs make the distinction.
Senior cats may rest longer, but a change in arousability, breathing, appetite, orientation or movement should not be dismissed as normal ageing. Compare the whole daily pattern.
An occasional pause may be ordinary, but repeated abrupt sitting can reflect paw, joint, back or neurological discomfort. Observe the whole gait without forcing extra movement.
Uneven light or viewing angle can briefly make pupils look different, but true unequal pupils are not normal. Recheck in even light without shining a torch into the eyes.
A brief rough meow can follow heavy vocalising or dry air, but recurring or persistent hoarseness may involve the mouth, throat or airways and cannot be diagnosed from sound alone.
A small amount of light wax may be present, but dark debris, odour, redness, pain, discharge or repeated head shaking needs veterinary assessment before treatment.
A cat may briefly check scent and postpone toileting, but repeated sniff-and-leave visits can reflect an unsuitable setup, social blocking, constipation or urinary pain. Confirm normal urine and stool rather than guessing.
A cat remaining in the litter box may be trying to urinate or pass stool, hiding because of stress, or struggling with pain. First confirm output because little or no urine can be an emergency.
One quick lip lick before a wanted meal can accompany anticipation. Repeated licking, hard swallowing, drooling or approaching food without eating may indicate nausea, dental pain, mouth irritation or stress.
A cat may shake a paw after leaving the litter box because granules stick between the toes, but repeated shaking can indicate an irritating litter, sore pad, damaged claw or debris.
Ears may feel warm after sleep because of bedding, room temperature and normal blood flow. Touch alone cannot diagnose fever; judge the cat's overall behaviour and use veterinary measurement when illness is suspected.
A photograph can make pupils look different because of angle, flash or reflection, but true unequal pupils in the same light can signal an urgent eye or neurological problem.
An occasional whisker can shed naturally and regrow, but multiple broken or missing whiskers with skin changes, rubbing or illness deserves investigation. Never trim or pull whiskers.
One ordinary swallow may clear food, but repeated hard swallowing after meals can reflect nausea or a problem in the mouth, throat or oesophagus. Record the pattern and treat breathing or swallowing failure as an emergency.
A tense hunched posture after eating can signal nausea, abdominal discomfort or pain. Compare it with the cat's normal resting posture and seek veterinary advice when it is new, persistent or accompanied by other signs.
A brief sleepy squint should clear quickly. If one eye remains closed after the cat is fully awake, assume irritation or pain and arrange prompt veterinary advice rather than trying human or leftover drops.
One dirty ear can reflect wax, mites, infection, a foreign body, allergy or skin disease. Compare both ears, avoid deep cleaning and let a veterinary professional examine one-sided debris with pain, smell or head shaking.
A brief startle, twitch or sudden run can follow a sound, dream-like REM sleep or unexpected touch. Repeated episodes with stiffening, unresponsiveness, abnormal breathing or prolonged confusion need veterinary assessment.
Drooling can follow brief relaxation or a bad taste, but new, persistent or heavy drooling can signal dental pain, nausea, toxin exposure, an oral injury or another problem.
Clear tearing can follow mild irritation, but squinting, pain, cloudiness, redness, injury or coloured discharge needs prompt veterinary attention because eye problems may worsen quickly.
Small irregular paw, whisker, ear or tail movements during relaxed sleep are commonly associated with dreaming. Stiffening, repeated whole-body movement, drooling or confusion afterward needs a different response.
Cat weight loss must be gradual and planned with a veterinarian. Measure all food and treats, protect muscle with suitable activity and seek help immediately if an overweight cat stops eating.
A cat's nose can naturally change from wet to dry with sleep, grooming, drinking, room temperature and humidity. Nose moisture by itself cannot diagnose fever, dehydration or illness.
Slightly turned-out hind feet may reflect normal conformation, but a new stance can signal pain, weakness or joint, nerve or paw problems.
Warm ears alone do not prove fever. Thin ear skin changes temperature quickly with the room, sunlight, sleep, exercise and blood flow. Check the whole cat and contact a veterinarian when warmth accompanies illness, pain or an abnormal ear.
A cat losing weight despite a normal or increased appetite needs veterinary assessment. Measure what is actually eaten, then record thirst, urine, stool, vomiting, activity and body weight so the clinic can distinguish overlapping patterns.
Unplanned weight loss in a cat is a reason to arrange a veterinary examination, even when appetite still looks normal. Confirm the trend, measure actual intake and record related changes without delaying care to run a long home experiment.
Whiskers can orient toward nearby interest, but a persistent one-sided facial change deserves attention.
Occasional nose licking is normal grooming, but repeated licking can accompany nasal discharge, nausea, mouth discomfort, stress or something irritating the face.
A lowered head can reflect fatigue, pain, weakness, breathing effort or an individual resting posture.
Bowl acoustics may amplify normal drinking, but a new gulping sound can accompany thirst or swallowing difficulty.
Some cats relax this way, but a new withdrawn posture with reduced responsiveness can indicate discomfort or illness.
A cat that approaches or steps over food without eating may be interested but unable or unwilling to eat because of nausea, mouth pain, smell loss, bowl setup, stress or illness.
Running before using the litter box may reflect routine or urgency, but repeated dashing with straining, pain or little urine can signal a medical problem that should not be dismissed as zoomies.
New touch sensitivity can be caused by inflammation, injury, parasites or pain around the head..
One ear can briefly feel warmer after sleep, sun or lying on that side, but persistent warmth with redness, discharge, swelling or pain deserves veterinary assessment.
Angle, flash and normal eye structures can create unequal reflections, but a consistent difference deserves examination..
A low crouch can signal fear, pain, weakness or an attempt to remain hidden..
A brief skin twitch can be a normal touch response, but repeated rippling with biting, pain, frantic running or skin changes can reflect irritation, pain or another medical problem that needs assessment.
Flakes near the lower back can reflect dry skin, reduced grooming, parasites or skin irritation. Learn what to check, what to change safely and when professional help matters.
A greasy coat can appear when grooming becomes difficult or skin oil and debris build up. Learn what to check, what to change safely and when professional help matters.
A suddenly greasy coat can mean grooming has decreased or the skin has changed. Check appetite, movement, mouth comfort, weight and skin, then arrange veterinary assessment instead of repeatedly bathing the symptom.
A long, damaged or thickened claw may remain visible, and pain can alter normal retraction. Learn what to check, what to change safely and when professional help matters.
A new strong odor can come from dental disease, mouth injury or another health problem. Learn what to check, what to change safely and when professional help matters.
Dropping food can reflect mouth pain, missing teeth, food shape or difficulty coordinating chewing. Learn what to check, what to change safely and when professional help matters.
Pawing at the mouth after a treat may reflect a stuck fragment, irritation or existing oral pain. Remove further treats, check breathing and seek assessment when the behaviour repeats or other mouth signs appear.
Repeated one-sided chewing can signal discomfort on the opposite side or another mouth problem. Record the pattern without forcing an examination and arrange veterinary dental assessment.
A longstanding brief call before normal toileting may be an individual routine, but new or intensified vocalising can signal urinary urgency, constipation, pain or difficulty reaching the box.
A sliver of third eyelid may appear briefly as a relaxed cat wakes, but persistence while fully alert—especially with squinting, discharge, illness or one-sided change—needs veterinary assessment.
Unequal pupils in a cat are called anisocoria. A sudden or persistent difference can reflect eye, nerve or brain disease and needs prompt veterinary assessment—urgently with pain, trauma or vision change.
Black pepper-like specks on a cat's chin can be comedones from feline acne, but dirt, flea debris, infection and other skin disease can look similar. Do not squeeze or scrub them; photograph the area, clean bowls and seek veterinary advice if it persists or becomes inflamed.
Small paw, whisker, eyelid or tail twitches during relaxed sleep are often normal REM-sleep movements. Record a new pattern and seek veterinary help when movements are prolonged, violent, continue while awake or occur with stiffness, drooling, loss of awareness or confusion.
A new back-leg tremor while standing can reflect pain, weakness, nerve or muscle disease. Film natural movement, prevent falls and seek urgent care for sudden painful weakness or paralysis.
An occasional swallow during relaxed purring may simply move normal saliva, but repeated gulping, drooling, gagging or difficulty eating can indicate mouth, throat or oesophageal trouble. Observe the complete pattern and treat breathing or swallowing failure as urgent.
A cat may briefly hold one paw up while listening, anticipating movement or pausing during grooming. Repeatedly avoiding weight on the same limb—especially with limping, swelling or a wound—suggests discomfort and needs veterinary assessment.
A brief sprint before using the litter box may be excitement or routine, but urgency, pain and digestive discomfort must be ruled out when it is new.
Urinating at the front of the box often indicates limited space, entry preference, pain or a box the cat cannot position in comfortably.
Stool beside a clean litter box can reflect painful defecation, urgency, box design, litter preference or social pressure—not spite. Check health and output before changing the whole setup.
Greasy fur around one or both ears can come from skin oils, scratching, discharge or topical products; the ear canal should also be checked.
Slightly textured paw pads can be normal, but cracks, thickening, burns and persistent licking need attention.
Pupils normally change with light, but persistent inequality or a delayed response in one eye can indicate an urgent eye or neurological problem.
Brief hiccup-like movements after eating may follow fast swallowing, but coughing, retching and breathing trouble can look similar.
Brief trembling can occur with intense scent investigation or arousal, but repeated movement may reflect mouth pain or a neurological problem. Practical observations, a safe next step and clear warning signs.
Body shape and a relaxed stance can create a mild outward angle, but pain or joint change can alter posture. Practical observations, a safe next step and clear warning signs.
A clear increase in drinking or urine output deserves veterinary attention. Keep water freely available, measure the pattern and arrange an appointment instead of restricting access or guessing the cause.
A true resting respiratory rate can help describe a change, but visible effort is more important than the number. Count only while breathing looks comfortable and seek emergency care immediately for distress.
One soft stool may be monitored in an otherwise well adult cat, but repeated diarrhoea, blood or illness signs require veterinary advice—sooner for kittens and seniors.
A limping cat is showing pain even without crying. Restrict jumping, observe without bending the leg and arrange veterinary advice; major trauma, a dangling limb or sudden inability to use the back legs is an emergency.
A sudden change in a cat's behaviour can be an early health clue. Check appetite, water, toileting, breathing and movement before assuming stubbornness, ageing or a training problem.
A seizure is frightening but your priorities are preventing injury, timing the episode and contacting a veterinarian. Do not restrain the cat or place anything in the mouth.
Collapse or inability to stand is an emergency even if the cat gets up again. Call immediately, minimise handling and support the whole body during transport.
Pale or white gums can accompany anaemia, blood loss or poor circulation; blue or grey gums can signal inadequate oxygen. Treat colour change with weakness, breathing difficulty or collapse as an emergency.
A newly closed, painful, cloudy, bleeding or injured eye needs prompt veterinary assessment because corneal and deeper eye damage can progress quickly and threaten vision.
Suspected poisoning requires immediate professional advice because treatment depends on the exact substance, amount, route and timing. A cat may appear normal before serious effects develop.
High blood pressure in cats is often silent until it damages the eyes, brain, kidneys or heart. Senior cats and cats with kidney or thyroid disease benefit from veterinary blood-pressure checks; sudden blindness, seizures or collapse require urgent care.
Hypertrophic cardiomyopathy can be present before a cat looks ill. Fast or laboured breathing, open-mouth breathing, collapse, or sudden painful hind-leg weakness are emergencies; echocardiography and veterinary assessment are needed to identify the heart problem.
Eye discharge plus squinting usually means irritation or pain rather than a simple cosmetic stain. Compare both eyes, clean only surrounding fur and arrange prompt veterinary assessment.
Bald patches and repeated licking can result from parasites, allergy, infection, pain or stress. The pattern alone cannot reliably identify the cause.
Mouth ulcers in cats can be painful and may accompany dental inflammation, infection, kidney disease, trauma, burns or other illness. Do not apply human mouth products or force the mouth open; arrange veterinary assessment promptly when eating, drinking or comfort changes.
Red, swollen or bleeding gums are not a normal effect of age. Gingivitis, periodontal disease, tooth resorption and more extensive mouth inflammation can be painful even when a cat continues eating, so persistent change needs a veterinary dental examination.
A broken cat tooth may expose sensitive tissue or hide damage below the gumline even when the cat still eats. Prevent hard chewing, do not test or file the tooth and arrange a veterinary dental assessment; facial trauma, jaw misalignment or heavy bleeding is urgent.
Tooth resorption is a common, painful loss of tooth structure in cats and often begins where owners cannot see it. Jaw chattering, food dropping, head jerks or a red area at the gumline warrants a veterinary dental examination with radiographs—not home scraping or watchful waiting.
Repeated ear scratching can reflect mites, infection, allergy, foreign material or other ear and skin disease. Avoid cotton swabs, peroxide, oils and leftover drops; protect the ear from self-injury and arrange examination before treatment obscures the cause.
Ear discharge or a new foul smell can accompany mites, infection, inflammation, foreign material or a growth. Keep the ear dry, put nothing into the canal and arrange an examination before cleaning or leftover drops obscure the cause.
Repeated head shaking is a symptom, not a diagnosis. Ear inflammation is common, but pain, parasites, foreign material and deeper ear disease can look similar; avoid probing or drops and arrange veterinary assessment when it is new, frequent or painful.
Good cat dental care combines veterinary examination with realistic plaque control at home. Toothbrushing can help prevent buildup on clean, comfortable teeth, but it cannot remove established tartar, diagnose disease below the gum line or treat a painful mouth.
A new persistent head tilt can accompany inner-ear, balance or neurological disease. Prevent falls, record eye and walking changes and contact a veterinarian the same day.
A cat that suddenly stumbles, circles or falls needs prompt veterinary assessment. Keep the cat on floor level in a padded safe area, record eye and head movement only if this does not delay care, and treat inability to stand, seizures, toxin exposure or breathing difficulty as an emergency.
Unequal pupil sizes in a cat are called anisocoria. A sudden change can signal painful eye disease, nerve damage or another emergency, so compare both eyes without bright light and seek veterinary care immediately.
A visible third eyelid may briefly appear during sleep, but persistent or unequal protrusion can accompany eye pain, inflammation, dehydration, illness or nerve change. Photograph both eyes in equal light and arrange veterinary assessment rather than applying human eye drops.
A cloudy eye can reflect corneal injury, inflammation, pressure change, lens disease or other conditions that cannot be distinguished safely at home. New cloudiness—especially with squinting, redness, enlargement or vision change—needs prompt veterinary examination.
Sudden vision loss in a cat is urgent. Keep the environment unchanged, block hazards and seek immediate veterinary assessment because blood pressure and retinal disease may be involved.
A cat's nosebleed may follow trauma or nasal irritation, but clotting disorders, high blood pressure, toxins and nasal disease are also possible. Keep the cat quiet, do not pack or tilt the nose and contact a veterinarian—urgently for heavy, repeated or unexplained bleeding.
New noisy breathing may arise from the nose, throat or lower airways, and sound alone cannot show how serious it is. Keep the cat calm, record a brief natural video and treat open-mouth or effortful breathing as an emergency.
Blood in a cat's vomit can appear as bright red streaks, clots or dark coffee-ground material. Contact a veterinarian the same day, and treat more than a trace or illness signs as urgent.
A newly enlarged or tight abdomen can reflect gas, stool, fluid, organ enlargement, pregnancy, bleeding or urinary disease. Do not press on it; record the timeline and seek urgent care for pain, breathing difficulty, weakness or little to no urine.
Swallowed string, ribbon, yarn, floss or tinsel can anchor under the tongue or in the stomach and injure the intestine. Do not pull visible material or induce vomiting—call a veterinarian immediately.
Stool leakage can result from diarrhea urgency, constipation overflow, pain, anal disease or neurologic problems. Keep the skin clean, document stool consistency and awareness, and arrange veterinary assessment—urgently for sudden hind-limb weakness, trauma or inability to urinate.
Blood in a cat's urine is never normal and needs prompt veterinary assessment. Confirm whether urine is actually passing, record colour and clump size, and treat repeated straining with drops or no urine—especially in a male cat—as an immediate emergency.
Frequent small urinations can reflect lower urinary tract pain and may look similar to scent marking or constipation. Count attempts and actual output; repeated straining with drops or no urine is an emergency, particularly in a male cat.
New or persistent genital licking can signal urinary pain, skin irritation, discharge or another medical problem. Check actual urine output first, avoid creams and cleaning chemicals, and treat straining with little or no urine as an emergency.
Wet bedding, dribbling while walking or urine passed during sleep can represent true incontinence, overflow, urinary disease, pain or neurologic problems. Keep skin clean and dry, provide easy litter access and arrange veterinary assessment rather than assuming a behaviour problem.
A sudden strong urine smell can reflect a dirty box or concentrated urine, but persistent change with thirst, larger clumps, frequent attempts, blood or illness needs veterinary assessment. Odour alone cannot diagnose infection, diabetes or kidney disease.
Yellow gums, ear skin or whites of the eyes can indicate jaundice caused by bilirubin accumulation. It is not a normal coat-colour change and requires same-day veterinary assessment.
Dehydration in cats cannot be confirmed reliably by one home test. Reduced intake, vomiting, diarrhoea, fever and diseases that increase water loss can contribute. Track drinking, food, urine and general condition, keep water available and seek prompt care when the cat is unwell.
Warm ears, a dry nose or hiding cannot confirm fever in a cat. Look for a clear change in energy, appetite, movement and breathing, avoid human fever medicine and ask a veterinarian about safe temperature measurement and assessment.
A cat that is cold, weak or poorly responsive may have hypothermia, shock or severe illness. Move the cat to a dry warm environment, wrap loosely, avoid direct high heat and seek urgent veterinary care for profound weakness, pale or blue gums, trauma or breathing changes.
Lethargy means a meaningful reduction in a cat's usual responsiveness, movement or interest—not simply a long nap. Compare normal routines, record associated signs and contact a veterinarian when the change is clear, persistent or combined with poor intake, pain, vomiting or breathing changes.
Ear discharge is not normal cleaning debris when it is new, heavy, smelly, bloody or paired with pain. Mites, infection, inflammation and foreign material need different treatment.
A cat that suddenly seems constantly hungry needs measured food and weight records, not unlimited extra meals. Hyperthyroidism, diabetes, digestive disease, parasites, medication, competition and underfeeding are among possibilities; veterinary examination separates them.
A pot-bellied appearance can result from body condition, parasites, pregnancy, fluid, enlarged organs, poor muscle condition or other disease. Do not press the abdomen or start random dewormers; photograph the change and arrange a veterinary examination.
Muscle loss can occur even when a cat's body weight looks stable. Compare the spine, shoulders, hips and thighs over time, record appetite and activity, and arrange veterinary assessment because ageing, pain, kidney or thyroid disease and other illness can contribute.
A new lump on a cat cannot be identified safely by touch or appearance. Record its location and size without squeezing it and arrange a veterinary examination, especially when it grows, persists, ulcerates or occurs with weight loss, poor appetite or lethargy.
More litter-box visits can mean frequent painful tiny amounts or a true increase in urine volume. Both require veterinary assessment, while repeated attempts with little or no urine are an emergency.
A scab, ulcer or sore that persists, enlarges or repeatedly returns needs veterinary examination. Infection, allergy, parasites, self-trauma and skin cancer can resemble one another, so document it and avoid human creams or repeated home treatment.
An open wound on a cat may hide deeper trauma or contamination. Control active bleeding with steady direct pressure, prevent licking, keep the cat quiet and contact a veterinarian; heavy bleeding, chest or abdominal wounds, shock or exposed tissue is an emergency.
Patchy hair loss can follow itching, parasites, infection, allergy, pain or overgrooming. The pattern is useful evidence, but appearance alone cannot identify the cause.
A cat bite can leave a tiny puncture that seals over bacteria and later forms a painful abscess. Prompt veterinary assessment is safest; do not squeeze or lance swelling, and seek same-day care for fever signs, poor appetite, spreading swelling or marked pain.
Cat burns can deepen after the event and are difficult to judge beneath fur. Stop the source safely, cool or flush only as appropriate, cover loosely and contact a veterinarian; electrical, chemical, facial, airway, large or deep burns require immediate care.
A small insect sting may cause local pain and swelling, but rapidly increasing facial, lip, tongue or throat swelling can threaten breathing. Keep the cat calm, contact a veterinarian before giving medicine and seek emergency care for breathing difficulty, collapse or repeated vomiting.
A suspected venomous snakebite is an emergency even when punctures or swelling are hard to see. Carry the cat, keep movement minimal and travel to a veterinary emergency service; never cut, suck, ice or tourniquet the bite.
Fleas can cause itching, flea-allergy dermatitis, tapeworm exposure and dangerous anemia in heavily infested kittens. Confirm signs with careful combing, use only veterinarian-recommended cat products and treat every pet and the environment as one coordinated plan.
An attached tick should be removed promptly with a suitable tool or fine-tipped tweezers, grasped close to the skin and pulled with steady pressure. Avoid bare fingers, heat, petroleum jelly and cat-unsafe pesticides, then monitor the bite and the cat's health.
Urine leakage during sleep is not deliberate house-soiling. Protect the skin and bedding, record the pattern and arrange veterinary assessment for possible bladder, urinary, mobility or nerve-related causes.
Ringworm is a fungal skin infection—not a worm—and its appearance overlaps with mites, allergy and other skin disease. Arrange veterinary testing, reduce shared hair and dust, follow the full treatment plan and protect vulnerable people without abandoning or harshly isolating the cat.
Cat chin acne often appears as blackheads or dark debris around hair follicles, but swelling, pain, pus and crusting can signal deeper inflammation or infection. Do not squeeze or scrub the chin; use gentle hygiene and veterinary assessment when it persists or becomes sore.
Brief skin ripples can follow touch, insects or arousal, but frequent or intense back twitching with biting, pain or frantic running deserves veterinary assessment.
Flakes in a cat's coat can accompany reduced grooming, dry or oily skin, parasites, allergy, infection, pain or systemic illness. Check the whole cat, avoid human shampoo and supplements, and arrange assessment when dandruff persists or comes with itching, hair loss or health changes.
A sudden new smell can come from the mouth, ears, skin, urine, stool or anal area. Locate the source without forcing handling, then arrange care for persistent odour or illness signs.
Night-only urination outside the box can reveal darkness, access difficulty or quiet blocking, but urinary disease must be ruled out first.
A cat that suddenly stops jumping may be protecting a painful joint, paw, spine or abdomen. Treat the change as health information rather than laziness or normal ageing.
A cat that repeatedly eats litter needs veterinary advice. Curiosity can occur in kittens, but pica may accompany anaemia, digestive disease, nutritional problems, stress or other illness.
