Cat Feline Panleukopenia: Prevention and Welfare

Feline panleukopenia, caused by feline parvovirus, is a highly contagious and often fatal disease that causes severe suffering in unvaccinated cats, particularly kittens.

Key Facts

Feline parvovirus is extremely environmentally stable and can persist for months to years on surfaces
Mortality in unvaccinated kittens can exceed 90% without intensive veterinary care
Clinical signs include severe vomiting, profuse diarrhoea, dehydration, and collapse
Vaccination is highly effective and is considered a core vaccine for all cats
Shelter outbreaks can devastate cat populations and pose major welfare emergencies

Welfare Considerations

Panleukopenia causes extreme suffering: uncontrollable vomiting, bloody diarrhoea, profound weakness, and rapid deterioration. Kittens may die within 24-48 hours. Surviving cats require intensive hospitalisation with intravenous fluids, nutritional support, and supportive care. Shelter cats are particularly vulnerable when vaccination coverage is incomplete. The disease is almost entirely preventable through vaccination, making outbreaks in shelter populations a significant welfare failure.

What You Can Do

Ensure all cats receive core vaccinations including feline parvovirus from 8-9 weeks of age
Support TNR programmes that include vaccination of feral cat colonies
Donate to shelters running effective vaccination programmes
Isolate any new cats before introducing them to existing pets to prevent disease spread
