Silvio is scheduled for surgery tomorrow morning.
UPDATE (10/14 6:20pm) - Silvio had his surgery and everything went well. He should be able to come home tomorrow. Thanks for all the good wishes and concern!
Yet another UPDATE (10/15 7:20pm) - Silvio is home now. I wish I could say that he was resting comfortably, but he isn't. He is trying like hell to lick his privates. The Elizabethan collar he is wearing will not allow him to lick anything. So he is put out about it. Plus he looks ridiculous. More later (with pictures!).
