Does my indoor cat really need a yearly rabies shot? Is it harmful?

Updated On September 23rd, 2025

Pet's info: Cat | Mixed Breed | Male | neutered | 1 year and 2 months old | 13 lbs

Mars will be going to the vet in November to get his second rabies shot. I read an article on Rabies vaccinations and how animals are required to get the shot more than they should be. Is this true? Is a yearly vaccination harmful to him? He’s a strictly indoor cat.

Mars definitely needs this Rabies shot. The second Rabies shot actually completes the Rabies vaccine series. He would be considered unvaccinated without it. What I recommend is an unadjuvented vaccine for cats. Some clinics have a 3 year one and others only a 1 year due to the expense of the 3 year. Even being strictly indoor Rabies is very important. Bats can get into a house and bite without leaving a large wound. So a 1 year nonadjuvented Rabies is safer than going unvaccinated!
