My cat got its leg trapped in a door and his leg is swollen. It's the leg on th upper part of the picture. When it first happened he could put a little bit of pressure on it but now its swollen and won't put any pressure on it. I have given him some food and he can walk but he limps. He doesn't seem to be in pain but when I touch his leg he screams. For this reason I have not felt the leg to see if it's broken. He also has a small cut on the side of his leg where he trapped it in the door. I was wondering if anyone could tell me if it's broken and tell me what to do other than take him to the vet tomorrow.
