✓ Squinting usually means discomfort
✓ Do not use old or human eye drops
✓ Cloudiness or trauma needs prompt assessment
✓ Prevent rubbing during transport
Cats can deteriorate quickly with some eye problems. Squinting, holding an eye closed or a cloudy surface indicates discomfort and should not be treated with leftover drops.
Separate tears from a painful eye
A small occasional clear tear differs from persistent watery, mucus-like, yellow, green or blood-tinged discharge. Squinting, frequent blinking, holding an eye closed, light avoidance, redness or cloudiness makes pain more likely. Record whether one or both eyes are affected and whether sneezing, nasal discharge, reduced appetite or illness signs occur at the same time.
Clean only what is outside the eye
Wash your hands and use a soft clean pad moistened with plain sterile saline or another method specifically recommended by the veterinary team. Wipe loose material from the surrounding fur without touching the cornea, forcing the lids apart or reusing the same pad between eyes. Stop if handling increases pain or distress.
Avoid drops chosen by appearance alone
Different causes can look similar, including conjunctivitis, corneal injury, foreign material, eyelid problems and deeper inflammation. Do not use human eye drops, tea, homemade salt mixtures, skin products or leftover medicine. Some steroid-containing drops can worsen a corneal ulcer, and antibiotics do not treat every cause.
Arrange care on the correct timeline
Contact a veterinarian promptly for persistent discharge, squinting, redness or a newly closed eye, even if appetite is normal. Seek urgent care for cloudiness, severe pain, a visible wound, chemical exposure, marked swelling, blood, unequal pupils or sudden vision change. A protruding eye or major trauma is an emergency.
Reduce spread when infection is possible
Until assessed, wash hands after eye and nose contact, avoid sharing pads and clean bowls or bedding normally without strong fragrances near the cat. Separate close contact from vulnerable cats if the clinic recommends it. Do not assume every discharge is contagious, but mention household cats, vaccination history, new arrivals and respiratory signs to help the veterinarian choose appropriate testing.

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.
