I know how you feel - Hanna's going in for her spay on Wed. morning. I am going to miss her so much overnight, but I know she will be happier. In my experience (although it has been a few years, Bo is 13 and my last male kitten) neutering is easier than what the females go through. It really didn't phase him at all, just a little sleepy the day after, then he was back to his old self.
