I didn't realize that you were supposed to VAX animals, (I haven't owned an animal other than fish and a bunny in at least 10+ years though) now that I think about it, I remember my mom giving our dog a shot on the back of her neck shortly after we moved from the country to a small town. They were always on her back about her animals so I am sure that living in the town had something to do with the shot.
I had many cats in my childhood, and we never once took any of them to a vet. I had one of my cats for thirteen years, the only time she went to the vet was to be fixed and at that time my sister was interested in being a vet and she was able to shadow the vet when he was fixing my cat, I will have to ask her is she received any shots at that visit. (She didn't stay at the vets office, she came home as soon as she woke up.) She was almost 14 and in good health when she just disappeared one day. (She used to hide in the car by the battery, so my mom thinks that she got stuck in someone's car and lost, I have my own opinion on what happened to her but that is a different story, but we lived in a town that had big owls, bald and golden eagles, and hawks and they were know to take off with small dogs so its possible that she was taken by one).
