I had Gracie spayed in Jan...and I didn't even confine her for that..and she had stitches...but I did put a onesie on her to keep her from messing with the incision. The jumping is the main thing..and she didn't feel like jumping the first 2 days..but after that we had to put things in front of the couch and chairs to keep her from trying. I don't know about boys and neutering...
