Cat was bitten on the lower back a few weeks ago leading to an abscess. The vet prescribed pain killers as there seemed to be no infection and he wore the collar a few days and all seemed fine. However, the fur still hasn't grown back and he sometimes seems sensitive there. I've seen him licking it a few times, but obviously cats do that anyway and he's definitely not doing it obsessively. Does anyone think it looks like he needs to be seen again? It's not a vey good photo but there's not a lot to see under the fur other than skin and a small scab.
