The vet should have one. If they don't, then maybe you need to consider finding a vet who is more set up for handling cats! I mean, if they don't have a cat sized muzzle, what else are they missing in the cat size? I would really wonder about this! My vet has SEVERAL for cats - my Vita gets to use one sometimes.

Some vets just don't like to work with felines. The veterinary hospital I go to is owned by one doc, but he has 3 or 4 vets working for him. One of those does NOT like cats, she has been bitten one too many times and she is afraid of them. The receptionist does her best not to put cats on that vet's schedule, but sometimes when I go in with an emergency that doc is the vet working. And she always puts the muzzle on each and every cat before she does a thing.

Vets can focus their practice, dogs, farm animals, we have 2 which are cats only in Providence, RI. So maybe this vet just isn't too comfortable with cats and doesn't invest in the muzzle and such for pets he prefers not to see anyway.

I think a few PTers work with vets and I will be interested to see what they post here!
