My boyfriend and I just took my 5 month old kitten to the vet to be neutered. When he came home I expected that he would be drowsy or out of it, but he's the exact opposite! He's already the most playful kitten I've ever owned, but this is almost like possession. He tears around the room, jumps onto and off of things, and rolls all over the floor trying to get his cone off. The vet told us to keep him from doing these things but how are we supposed to stop him?! I've confined him to one room only, where he has food, water, and a litter box, and I even put stuff on all the high places in the room so he wouldn't jump up. Yet despite seeing the large objects that are in his way, he STILL jumps up, smacking right into the object and then falling to the floor. HE KEEPS DOING THIS. I'm afraid he's going to tear his stitches. I'm not home all the time so I can't constantly monitor his actions to make sure something doesn't go wrong. What do I do?! How do I calm him down? HELP.
