I have a baby squirrel who was attached by a cat and is paralyzed from the waist down (legs and tail), he is able to potty on his own and has a healthy appetite. We just found him last night and he is very alert and pulling himself up the side of the cage. How can you tell if they are in pain, he doesn't seem to be able to feel, but I just want to make sure he is not in any pain.

Also, I am looking on how to build a squirrel cart (wheel chair) so that he does not have to drag his body on the ground and get sores. I've searched the internet; however, I only see them for dogs and cats. Has anyone ever made one? Any advice?
