You know how sometimes if we sit or lay in an odd position a hand or a foot, or even a whole arm or a leg can "go to sleep" -- ie feeling is lost for a little while. I was wondering if that can happen to cats. The reason I ask is because I've noticed that several times lately after Rocket has been napping, right after he gets out of bed he won't put any weight on one leg. He holds it up and shakes it -- kind of like he's trying to get feeling back in it (just what we'd do) -- and then after a couple minutes he's fine.
