Biopsy tomorrow

I want to say thanks first of all to everyone for kind wishes about my cat. In fact his tumor is not the size of a golf ball, and the first biopsy did not actually say "cancer" -- it said: undefinitive, maybe this is plaque related? Because you never brush the cat's teeth? It's only the fact that a second tumor suddenly appeared that made my vet freak out and feel totally un-up to the task. That and all the many weird red spots going all the way back the roof of his mouth down his throat. Anyway, the cat is about as he's been lately, and the tumor is not bigger today than yesterday, though certainly that's big enough.
