The virus attacks the respiratory tract, mouth – with ulceration of the tongue, the intestines and the musculoskeletal system. Calicivirus is highly contagious to other unvaccinated cats.
Cats typically catch FCV after coming into contact with other infected cats. Calicivirus is resistant to some disinfectants, so cats can come into contact with the virus in almost any environment. Cats without vaccinations are at higher risk, as are those with a lower immune system due to pre-existing infections or diseases.
What are the signs of FCV?
If your cat has calicivirus, the following symptoms will typically present themselves suddenly:
- Loss of appetite
- Eye discharge
- Nasal discharge
- Development of ulcers on tongue, hard palate, tip of nose, lips or around claws
- Difficult breathing after development of pneumonia
- Arthritis (inflammation of joints)
- Painful walk
- Bleeding from various sites
