Just like people, kittens and cats sneeze for a variety of reasons. An occasional sneeze is very normal but constant sneezing could be a sign of an illness.
Why Do Kittens Sneeze?
If you notice your kitten sneezing now and then, there’s a good chance that it’s just reacting to some dust or fur that’s tickled its nose. But if your kitten continues to sneeze it might indicates something is definitely not right. You might want to send your kitten for a check up with a vet.
Some cats and kittens do have allergies. Mold, dust, perfumes, smoke, pesticides and cleaning supplies can all trigger sneezing. If your kitten is sneezing and scratching or has red eyes or nose, there’s a good possibility that it’s suffering from an allergy.
Upper Respiratory Diseases
Constant sneezing, especially when accompanied by other symptoms such as lethargy, lack of appetite, eye or nasal discharge, diarrhea, coughing, or breathing difficulties, could well be a sign of a viral, bacterial, or fungal upper respiratory infection.
If you see these symptoms, you may have a kitten with an illness such as feline herpes or feline immunodeficiency virus (FIV) or a less-severe illness such as peritonitis or chlamydia. Most of these diseases are preventable with vaccinations but are more difficult to treat once your cat has contracted one of them.
One fairly common and highly contagious disease that can cause sneezing and breathing issues is feline calicivirus. Most vets vaccinate kittens so they won’t catch this disease, but if they do, it usually runs its course within a week or so.
If the symptoms are severe or if your kitten sneezes blood, take it to the vet as soon as possible. She may prescribe a nasal decongestant or antibiotics, depending on what’s causing the sneezing. A humidifier near where the cat sleeps may also help with minor breathing issues.
