My vet tells me to use the pink stuff (can't remember its name) and always makes sure it isn't too bad - the rescues vet just laughs it off (normally while showing me a war wound of his own). I have had to have 2 courses of ab's due to infected bites though - the second was PEbbles, and she had to go back the day after - she got put on the table with the remaining tablet, and the vet was told if she really wanted her to have it, they would have to do it. One look at my finger, and vet decided she didn't really need it!! One of our previous trainee vet nurses had to go to hospital after handling Blackie due to how much she had scratched and bit - I had warned her before she went to put her in the cage, but she ignored me. Luckily, she had clipped her claws while she was sedated, but it was still a mess. At least 3 of my cats have bit/scratched at the vets, it is a wonder I am still allowed to go (and no wonder the vet is cautious when I take new cats!!)
