My cats are due for vaccination soon and I was wondering what the current info is on 1 vs 3 year rabies vaccination. I've read that people say the 3 year one is not good and has a higher cancer risk. However I asked my vet about it and she said that if it is between getting it every 3 years vs. every year, there probably is not a much greater risk because if you are giving every year they get more injections than with the 3 year so there may be more chance of a reaction due to that...
