I worked for a vet in st marys for almost 3 years, and this is what we recommended to our clients.
Outside kitties:
3 year Rabies after the inital one at 12 weeks, booster at 1 year and again at 2 years
FVRCP (Feline distemper) Annually
FELV (Feline Leukemia) Annually
FIP / FIV Annually if at high rsk (outside cats/intact males that like to fight)
Inside kitties
3 year Rabies after the inital one at 12 weeks, booster at 1 year and again at 2 years
FVRCP (Feline distemper) every 3 years, after the initial series of 3 and boosters at 1 year and 2 years
I know its a bit confusing, but more and more vets are trying to tailor vaccine protocols to individual cats instead of just doing a one size fits all type of approach. If you want more info, just pm me!
