[QUpoorOTE=Dranarius;31575486]How uncoordinated are we talking? This badly? http://www.youtube.com/watch?v=xLlL24shW7E[/QUOTE]
Awe poor kittkitty. My cat can't jump from place to place. And walks into walls. I am in med school, so dont really know much about cats.

I would consider the possibility of a vision problem as well then. He might not jump because he's unsure of the distance, same with running into the walls. Even if it's a coordination problem, It's impossible to say without actually taking a look at him. The problem could be muscle/nerve related, proprioception related, brain related, etc.(Replace pronouns as needed if the cat is female)
