Is feline calicivirus fatal?

Feline calicivirus (FCV) is typically not fatal for most cats, but it can be serious. Here’s a breakdown:

🐱 General Outlook

  • Most cases: FCV causes mild to moderate upper respiratory and oral infections. Most cats recover fully with supportive care.
  • Rare strains: Some variants of FCV can be especially virulent and deadly, leading to severe systemic illness and even death.

⚠️ Risk Factors

  • Young kittens, elderly cats, and those with compromised immune systems are more vulnerable.
  • Shelters and breeding colonies often see higher transmission rates due to close contact.

🛡️ Prevention

  • Vaccination helps reduce severity and spread, though it doesn’t guarantee complete protection against all strains.
