Immunizations are started at 6-8 weeks of age and are repeated every 3-4 weeks until the kitten is 4 months old. The routine or core vaccinations will protect your kitten from the most common diseases: feline distemper (panleukopenia), feline viral rhinotracheitis (feline herpes virus 1), calicivirus, and rabies.

What happens if you don't vaccinate your kitten?

Cats can develop a number of illnesses if they don't have their shots, but feline leukemia is one of the worst. This illness is a top cause of feline death with a fatality rate of nearly 90%. Feline immunodeficiency virus, also known as cat AIDS, is a serious, lifelong illness transmitted by unvaccinated cats.

Is vaccination necessary for kittens?

Kittens are born with a natural immunity for the first few weeks of their lives. Vaccinations should start at around 8 weeks old and there are series of about 3-4 follow-ups about 2 weeks apart. Your cat should also receive a vaccination every 1-3 years going forward.
