Here is my issue. My cats are due for their shots, The younger one I have spread her shots out monthly and she just requires her rabies now, but my older one is due for all of her yearly shots. She had an allergic reaction last year where her face swelled up and she had to go in for allergy protocol with the IV Benadryl. I live on a military post and I spoke with the vet office here. They will not accept titers. She is required to get her shots. I don't know if I want her to have to go back multiple times to get an IV placed each time she gets shots. Should I just get it all knocked out at one time? That way she doesn't have to be stressed out every few weeks? If I had the choice, she wouldn't get them done at all, but that is not an option.
