I know vaccination is a controversial subject and some years ago there was a strong anti-vaccination view around so I stopped having my cats jabbed. They were fine for about five years and then they all went down with cat flu one after the other. They were very sorry for themselves, had to have antibiotics etc, and I went back to having them jabbed after that. I think I probably agree that cats really only need jabs every second or third year but that it's in vets' financial interests to do it annually, and of course vets make you go through the whole course of injections again if you do miss a year. Actually, my dog missed one year's jabs due to the vet's oversight (when she was having lots of other treatment) and the vet happily gave her the normal, routine jab about eight months after it was overdue when we spotted the mistake, no mention there of needing the whole course again, so that tells you something about their true views!
