Feline upper respiratory infection is a highly contagious disease which affects the nasal passages and sinuses of cats and kittens. It's common in animals adopted from shelters or multi-cat households and in kittens rescued from stray populations. If your kitten develops an upper respiratory infection (URI), you should nurse it back to health and watch for warning signs that may indicate a need for hospitalization.
