Why in the world would he "ignore" your recent paperwork???? That's ridiculous!! Was it a photocopy or something instead of the original certificate? Even so, all he had to do is call the place where you had his shot given in October!!!! Rabies shots CAN cause serious allergic reactions ... my Grace CAN NOT ever have another rabies shot ... per MY VET! The last one she had, she had an anaphylactic reaction and had to stay overnight at the clinic! I would do some serious checking into this situation! As it is, the law insists on them having rabies vaccinations on a yearly basis, even though the vet will admit they are good for 3 YEARS ... certainly only 3 MONTHS apart is way too much! I'm glad that your kitty didn't have a bad reaction! But that vet needs to be questioned for sure!
GOOD LUCK!
