Are all kitten and cat vaccines necessary? - Countryside Veterinary Clinic

Yes. If we're recommending them, that's because we think they're necessary for your cat. The rabies vaccination is required by law for all of our domestic dogs, cats, and ferrets, and upper respiratory vaccines are necessary to keep your cat healthy. An additional vaccine may be necessary depending on your cat's lifestyle.

Are all kitten and cat vaccines necessary? - Animal Hospital of Statesville

Technically, no, they're not all necessary, especially those considered non-core, if you will. There are certain lifestyles that your cat may live and certain things they may be exposed to. But as far as the core vaccines, yeah, we consider those necessary for all pets unless certain medical conditions would go against that, but those are uncommon. And then back to the whole legality of rabies vaccine—that one is considered very necessary. As a matter of fact, it's a legal requirement.
