Our cat CC had all of his kitten shots and a booster at one year but hasn't had anything since. He's four now. He is indoor, but I'd like to take him outside on a harness. I firmly believe in limited vaccinations with my dogs, only doing puppy series, booster a year later, rabies every three years by law and then I'll titer test for parvo and distemper. No way I'd ever do yearly vacs for dogs, but I don't know much about cats. There has only been three cases of rabies in the province in the last decade, so I'm not worried about that, but I don't know about the others. It's been proven that with dogs, after puppy shots and one booster most dogs will be protected against parvo for life, but vets still push yearly or every three years shots. My vet doesn't push shots and said that CC didn't need anything speficic when he started living with my dog, but not sure about the basics.
