I know a lot of vaccines are somewhat "optional" for indoor only cats, such as the Felv and fiv shots, and even rabies where its not required. I was wondering about the distemper shot. Is that something you wouldn't bother with each year also for an indoor only, or do you do that one regardless? I know its a lot more contagious than the other diseases, so wanted to find out if Riley should have one every year. Thanks.
