I found 2 kittens on the side of the road 6 days ago.?

I'm wondering if it was a cat bite. They are deep and tend to get poisonous. Like, could be an abcess. But you've had it at the vet, you'd think he would have said so. If it's not too much trouble, take the kitten back to the vet. And thank you on behalf of all unwanted cats that you chose to take the time to rescue them.
