All my cats had their vaccination when they were kittens but none of them have been update on their shots for a couple of years now. I was told before that every cats should have their Rabies shot even if they are inside cats. I do volunteer in the shelter couple of times a week. My Joey has caught URI a few times and he isn't a strong to begin with. What do you guys think? Do you guys recommend getting vaccination every year? They are being expose to germs every time I come home from the shelter. Please reply. Thanks!!
