Does he rhink he's a dog? Usually we see this in dogs?
Don't worry it will soon heal, as soon as the abces is opened the worst is over.
Thank you to everyone who posted comments and good wishes. He is doing better, and the place where the stitches came out is healing nicely along with the rest of the incision. He seems to have resigned himself to the cone. Actually yes, he does seem to think he is a dog, as he plays fetch, follows me around the house, and is unable to meow (in all fairness, he can't bark either). The vet says she sees about two cases a month of ruptured anal sacs (her practice is limited to cats). I had never heard of this before, and he just had his annual checkup in November.
