I am sure one of our resident vets/techs will reply, but I can tell you that my adult cats get vaccinated every 3 years for distemper and every year for rabies (Purevax. sp?). Kittens first shots are spaced out over a period of weeks (months?).

Rabies shots are required where we live, and having had a bat in the house once, a wise thing to do. We do the distemper shots because it is an airborne disease. I feel better knowing they are protected for those times when they need to spend part of the day in a kennel/cage at the vet's office (e.g. following a teeth cleaning or surgery). If a cat in a nearby cage has distemper and sneezes..... Also, I volunteer at an animal shelter, so don't want to bring that home and expose them without having them protected against it.

Since our cats are indoor only, we skip vaccinations against FeLV since they must have direct contact (a bite for ex) to contract it. We lost an older cat to fibrosarcoma, which is suspected to be a vaccine associated cancer, after yrs of giving her the leukemia vaccine, so avoid having it administered to our current cats.

CAT VACCINATION SCHEDULE
Recommendations vary depending on age and health status of the cat, the potential of the cat to be exposed to the disease, whether the cat remains indoors or also goes outdoors, the type of vaccine, whether the cat is used for breeding, and the geographical area where the cat lives or may visit. These recommendations are consistent with the 2006 vaccination guidelines developed by the American Association of Feline Practitioners (AAFP).
CAT VACCINATION SCHEDULE

Distemper combination vaccine*

Begin as early as 6 weeks of age and repeat every 3-4 weeks until 16 weeks of age. Booster at 1 year after completion of initial series, then no more frequently than every 3 years.
