✓ Regular brushing reduces swallowed loose fur
✓ Frequent vomiting is not normal
✓ Coughing can be mistaken for a hairball
Cats swallow loose hair while grooming. Some hair may form a compact mass that is vomited, but frequent episodes should not simply be dismissed.
Reduce loose hair
Gentle brushing suited to the coat type can reduce shedding and help prevent mats, especially in long-haired cats.
Watch the frequency
Repeated vomiting, reduced appetite, constipation, lethargy or unsuccessful retching require veterinary advice.
Hairball or cough?
Respiratory coughing can look similar to retching. A short video of an episode can help your veterinarian assess it.
Describe the episode before naming it
Record whether the cat coughs, retches, vomits food or produces a compact tube of hair. Film from a safe distance when possible. Breathing posture, wheezing and repeated coughing need veterinary assessment rather than hairball treatment by assumption.
Reduce loose hair without hiding a medical problem
Use coat-appropriate gentle brushing, prevent mats and discuss nutrition or hairball products with the veterinary team before adding them. Repeated vomiting, poor appetite, weight loss, constipation, pain or lethargy needs investigation for causes beyond swallowed hair.
