Cat Vaccination and Infectious Disease Welfare

Vaccination protects cats from highly infectious diseases that cause significant suffering and death, with incomplete vaccination coverage in cat populations creating ongoing welfare costs.

Key Facts

Feline panleukopenia, cat flu (herpesvirus and calicivirus), and feline leukaemia are the core preventable diseases in UK cats
Cat flu causes chronic carrier states in recovered cats, causing periodic recurrence of painful eye and respiratory disease
Feline leukaemia virus causes fatal cancer and immunosuppression, with no cure available
Vaccination uptake in UK cats is estimated at 50-60%, leaving significant proportions of the population susceptible
Herd immunity thresholds for highly contagious diseases like panleukopenia require high vaccination coverage
Some indoor cats are under-vaccinated due to owner assumptions about risk, despite occasional indoor exposure routes

Welfare Considerations

Vaccination is one of the most cost-effective welfare interventions available for companion cats, preventing diseases that cause significant suffering at the individual and population level. Incomplete vaccination coverage, driven by cost, access barriers, and misconceptions, leaves both individual cats and entire populations at unnecessary disease risk. Veterinary outreach, subsidised vaccination programmes, and owner education are all important for improving coverage.

What You Can Do

Keep your cat's vaccinations up to date according to your vet's schedule
Ensure kittens receive their primary vaccination course at the appropriate age
Support low-cost veterinary vaccination initiatives in your area
Advocate for pet insurance to include vaccination costs to improve uptake
Educate other cat owners about the welfare importance of vaccination regardless of indoor-only status
