Cat Feline Panleukopenia Prevention

Feline panleukopenia (parvovirus) is a highly infectious, often fatal disease preventable through vaccination, with significant welfare implications for unvaccinated cats.

Key Facts

Feline parvovirus causes severe vomiting, diarrhoea, and immune collapse
Kittens are most severely affected, with mortality rates up to 90% in untreated cases
The virus is extremely hardy, surviving in the environment for years
Vaccination provides durable protection with kitten series and adult boosters
Outbreak control requires thorough environmental disinfection with parvocidal disinfectants

Welfare Considerations

Panleukopenia causes severe and prolonged suffering - vomiting, diarrhoea, and immune collapse over days to weeks. Vaccination is highly effective and the welfare case for vaccinating all cats is unambiguous. Outbreaks in shelter settings require immediate response to prevent welfare catastrophe across vulnerable populations.

What You Can Do

Ensure kittens receive full vaccination series starting at 8-9 weeks
Maintain adult booster vaccinations according to veterinary guidance
Support shelter vaccination programmes that prevent panleukopenia outbreaks
