Okay, I've been watching him for several hours. And what I just found is horrifying. Now that the blood has dried, I can see that part of his bone has penetrated his skin. The poor thing. Should I just have him put down? How much does that usually cost? I feel so bad for him. I have been giving him Torbugesic Suspension for pain. I had some left from a previous incident with one of my kittens. Any advice?
