What is it?
Feline calicivirus is a contagious viral disease affecting the respiratory system and oral cavity. It is a common cause of upper respiratory infections in cats.
How is it spread?
The virus spreads through:
- Saliva and respiratory secretions
- Direct contact with infected cats
- Contaminated objects (bowls, bedding, hands)
Calicivirus can persist in the environment and is common in multi-cat households and shelters.
Clinical signs may include:
- Sneezing
- Oral ulcers (tongue, gums)
- Drooling
- Fever
- Lameness (in some strains)
Rare virulent strains can cause systemic illness.
Why vaccination is important:
Vaccination does not eliminate all strains but greatly reduces disease severity and the likelihood of severe complications. It is a core component of feline preventative care.
