Does my sphynx hairless cat need shots?
Six is barely ‘old’. Old in a cat is around 19 or 22 now. He needs the rabies to comply with state law, there’s a 1 year vaccine and a 3 year vaccine, find out which one your vet uses. If a mouse got into the house and he ate it, he could have worms if the mouse had the parasites. It won’t hurt to get a fecal exam done on him. We didn’t let ours go outside either but unknown to us a bird flew into the basement and one of ours got it. A week later we see worms in the poop in the litter box and all four cats needed to get treated.
