Currently I don't vaccinate my cats for FIP. They are strictly indoors and I don't ever board them. I vaccinate for Rabies according to state regulations and I vaccinate for distemper and felv every 2-3 years or whatever my vet recommends. We now also keep track of exactly where we vaccinate so we can watch for lumps. If my kitties went outside or if I fostered kitties I'd switch it up a little.
