Right now he still doesn't have all his hair back from when he had surgery in November (to remove the tumour and rebuild part of his jaw). So he is looking pretty rough.

They did tell me that one side effect of radiation is that the hair in the area irradiated may grow back white. But in his case it doesn't matter because he is an all white cat. So that is the only good thing about this entire process. (That and everyone at the vet's office fell in love with him)
