However, if your cat is excessively sneezing (more than just a few times a day or more than a few days in a row), a veterinary visit may be necessary. What can cause sneezing? Foreign material such as grass, small pieces of plant seed, etc.
Cats sneeze for many reasons, but if your cat or kitten sneezes a lot you may start to worry that there's something wrong. If sneezing is the only symptom your cat displays -- i.e., no discharge from eyes or nose, good appetite, no change in behavior or activity level -- then it is probably of no concern. However, when ocular or nasal discharge is seen, the cat may have a cold or upper respiratory infection.
