Kingsford went to the vet two weeks ago to get fixed. He come home fine, although I did find out he's FeLV positive. He's really calmed down - enough to make me nervous. He cuddles with me now, and I wonder if he feels extra warm. I really can't tell...How would I be able to tell if he has a fever? If he's sick, I want to get him to the vet but if it's just the neutering that's slowing him down then I won't worry.
