I do rabies (it's the law) and distemper (it was reccommended by my shelter and my vet), but I wouldn't ever do any of the other vaccines out there with my kits...too risky in my opinion. And being indoor-only, they don't really need anything else anyway.
Also, I do their shots at a 3-year-interval, not every year
There is a 3 year rabies out there, but some places say it must be done each year and don't offer the 3 year option.
Talk to your vet, though. Your circumstance may be different than mine...but this is what my particular vet reccommends.
Indoor cats need protection like outdoor ones - they may escape, or someone may bring something in with them. Vets will give 3-in-one plus rabies and some vets do a first worm/flea treatment with a shot.
