My cat is sneezing a lot: what are the causes?

Velto answer

Occasional sneezes are normal for cats: they help to expel dust or hair. When sneezing becomes frequent, the most common causes are cat flu (a respiratory infection), an environmental irritant, or an allergy. Any discharge, fever, or loss of appetite warrants a vet visit.

Cat flu, a common infection

Cat flu is a group of viral or bacterial respiratory infections. It is associated with sneezing, discharge from the nose and eyes, sometimes fever and lethargy. It is contagious between cats; vaccination greatly reduces the risk of a severe form.

Dust and irritants

Dusty cat litter, perfumes, smoke or household products can irritate the nasal passages. Changing the litter and airing the room is often enough to reduce sneezing.

Allergies and other causes

Some cats react to pollens or dust mites. More rarely, a foreign body in the nose, a dental problem, or a polyp can cause persistent sneezing, sometimes on one side only.

When should you see a vet?

Consult a vet if the sneezing lasts for more than a few days, is accompanied by thick discharge, blood, fever, breathing difficulties, or if the cat stops eating — especially in a kitten or an older cat.

Frequently asked questions

Is a sneezing cat contagious to humans?

The agents of feline cat flu are transmitted between cats, not to humans under normal circumstances. Isolate the sick cat from other cats and wash your hands.

Can I give human medicine to a sneezing cat?

No. Many human medicines are toxic to cats. Only a vet can prescribe a suitable treatment.
