Cats can get a number of upper respiratory infections, but feline calicivirus is one of the most common infectious agents in cats with respiratory issues. If your cat has clinical signs typical of a "cold," bring it to a veterinarian to learn more about the possibility of this illness.

If your cat is experiencing clinical signs such as sneezing, nasal congestion, inflammation and conjunctivitis in the eyes, or discharge from the nose or eyes, bring it to the vet for treatment. These are the most common signs of respiratory illness, but cats with calicivirus may also have ulcers on the tongue, hard palate, gums, lips or nose, according to VCA Animal Hospitals.

Your veterinarian will likely recommend a treatment plan you can use at home. As long as the infection is uncomplicated, your vet may prescribe an eye medication to treat eye discharge or other medications to treat symptoms that interfere with the cat's overall well being, VCA reports.

According to, this illness can be spread through saliva or inhalation, so if your cat interacts with other felines in the house, you may want to treat them, as well. With supportive care, your cat should be able to fight off the virus in about 20 days.
