Cat Infectious Disease Prevention and Vaccination

Core vaccinations prevent serious and painful infectious diseases in cats, representing a fundamental welfare intervention.

Key Facts

Feline panleukopenia, herpesvirus, and calicivirus are core vaccine-preventable diseases causing significant suffering
Feline panleukopenia can kill unvaccinated cats within days with severe gastrointestinal and immune system destruction
Herpesvirus causes chronic respiratory disease with lifelong recurrence during stress in infected cats
Rabies vaccination protects both cats and humans in regions where rabies is endemic
Indoor cats still require core vaccinations as pathogens can be introduced on shoes, clothing, and insects

Welfare Considerations

Vaccination is among the highest-impact welfare interventions available for companion cats. Core vaccines prevent diseases that cause severe suffering and death — panleukopenia devastates the immune system, feline herpesvirus causes chronic eye and respiratory problems, and calicivirus causes oral ulceration. Prevention through timely vaccination eliminates these welfare risks almost entirely. Even indoor cats need protection against pathogens with environmental routes of transmission.

What You Can Do

Vaccinate cats on the schedule recommended by your veterinarian and regional guidelines
Keep vaccination records and booster schedules current for all cats in your household
Ensure newly adopted cats are vaccinated promptly even before full health status is known
Support subsidized vaccination programs for cats in low-income households
Discuss titer testing with your vet as an alternative to routine boosters for some adult cats
