Good luck Rachel!
Well, Kloe was a hellraiser kitten (still is) when she was spayed so not sure if I can help or not. But expect her to be rather sleepy the first nite and don't let her jump if at all possible. (with Kloe - yea right) I kept her in the bathroom the first nite home and while I was gone the next day and it was useless b/c she was climbing and jumping all over the bathroom! The incision might be lumpy - that is just scar tissue - it smooths out eventually.
