Calicivirus causes respiratory symptoms in cats. Learn about treatment and vaccination options.

Feline calicivirus causes upper respiratory infection in cats. Together with herpesvirus, it's a major cause of "cat cold." Usually mild, but can be serious in kittens or immunocompromised cats.

Calicivirus Symptoms
- Sneezing, nasal discharge, conjunctivitis (red eyes)
- Mouth ulcers (tongue, lips)
- Anorexia, lethargy, fever
Treatment
No antivirals exist; treatment focuses on symptom management. Warm food, high humidity, and eye cleaning help. Antibiotics are used for secondary bacterial infections.
Vaccine Prevention
Regular calicivirus vaccination prevents infection. FVRCP 3-in-1 vaccine (panleukopenia, calicivirus, herpesvirus) includes it. Kittens start at 6–8 weeks, with 2–3 boosters every 3–4 weeks; the final kitten dose is given at 16 weeks or older.
