Are Rabies shots a must?

I've only given my 2 cats Rabies shots as of the last few years. Someone told me I need not do this. I let Luke out into a fenced in enclosure and chances are small that he would come into contact with a rabid animal or any animal. Feral cats pass through the yard once in a while but not too often and they never go near the enclosure.
 

I don't want to endanger my cat's health with unnecessary vaccines. I feed them raw and they seem very healthy.

The chances of an indoor cat being exposed to rabies are very low. Of course the risk depends on rabies rates in your area. However, most of the risk comes from legal requirements. In some areas, if an unvaccinated (or not current on vaccinations according to local law) pet bites or scratches somebody, even accidentally, they're immediately killed to test for rabies. So find out what your local laws are, so you can make an informed decision.

Also, rabies vaccines given after 6 months of age confer immunity for a very long time. At least 7-10 years, probably for life. So if you just want to protect the cat against rabies, one shot should be sufficient. But legal requirements are a whole different thing.

Interesting, thanks. Sounds like over-vaccination is very common these days.

I live alone and I very seldom get company and if I do, the cats keep their distance. I think I'm going to let their shots a break for a few years, maybe for always.
 

Since getting my cats on raw diet a few years ago I no longer need to use flea chemicals on them. They seem to be more naturally immune to fleas but I do need to use a flea comb on them and vacuum regularly.

I am against rabies vaccines after one of my kitties got sick after getting a "forced" one.  The problem I am having is finding a veterinarian in my area that will treat my cats without having been vaccinated against rabies.  They are indoor, always have been.  I finally found one in my area that agrees to a rabies titer.  Remarkably, after just having the initial 2 or 3 shots as a kitten, Charlie's titer came back very high against the virus, 5 years later.  Some cats don't hold the vaccine as well, and the titer comes back too low.
