Where to go from here.....

A few days ago Razz's leg or a guess I should say bone in the leg finally broke. The thing is he still acts the same. We both said he HAD to have a high tolerance to pain when he torn the ligament in his knee, but now I'm wondering if he just loves us sooo much that he pushes it back. He still jumps up when we walk in the room, will follow me all over the house, (if i'd let him) and just last night he jumped over the ottoman to get to me in the kitchen. I can't see putting him down, but should I. I just don't know what to do.
