I will tell you what I do but what I do is not what I WOULD do if circumstances were different. I still get the full vaccinations for my 4. Except the senior will not be vaccinated this year. She has not been in the best of health and I don't want to push it so I'm refusing to give her the shots. Even the rabies. IF I did not have a feral cat living in my garage and 2 dogs running in and out all of the time I would most likely not subject them to any of the vaccinations except maybe rabies. None of them go outside... ever. I would have to research it more but I think that is what I would do. Rabies is required by law here. Since there is a possibility, albeit remote, that something could be brought in from the outside, I do the full routine. That is just my situation though and I would suggest everyone check the laws in their municipality etc.
