Cats, usually middle-aged or older.

Upper Respiratory Infections in Cats

Animals affected

Cats and kittens


Upper respiratory infections, also known as URIs, are very common in cats. They are similar to colds in people, but they are caused by different types of germs.

URIs are especially common in kittens, and almost all cats will have experienced an upper respiratory infection by the time they reach adulthood. A very large proportion of kittens adopted from shelters suffer from URIs shortly after adoption.

Scratching or Licking the Skin (Itching) in Cats and Dogs

Scratching and licking the skin generally have similar causes. Excessively licking the skin is a way of scratching the skin. Skin irritation leading to itching is responsible for most instances of excessive licking and scratching.

A certain level of scratching or licking is considered normal in all animals. Also, both cats and dogs groom themselves with their tongues. Therefore, it is important to determine whether your pet is scratching or licking excessively, or whether he or she is engaging in normal behavior.
