Hard to say Lynette. I once had a cat that broke his back jumping out of a laundry basket on a coffee table (not even 2 feet off the ground). People think cats are these amazing athletic creatures, and sometimes they can seem indestructible, but the truth is, they are fragile little beings and can easily get hurt around the house. It's entirely possible he did hurt his leg either falling or jumping off the tall cat tree. I have an eight foot tree too, and my cats jump down onto my dinner table from it... and it sounds like someone dropped a 10 pound sack of potatoes, FAR from graceful. So far, no-one has been hurt, but I ALWAYS run in and "check" who-ever it was to be sure. I'd offer him two options to lay one, an ice pack under a big fluffy towel, and a heating pad under a big fluffy towel, and let him choose what feels better for him. I do this with all my injured, sick, or recovering from surgery cats, and they always choose one of the two. Did your vet do a neurological exam in addition to looking for sprains and injuries? Favoring a leg but NOT expressing pain during manipulations points towards something neurological. Which leg is he favoring? A rear leg? Neurological issues often start in the rear and progress forward as they worsen. Did your vet do a toe pinch test on all legs to test for a pain reflex? What about pin prinks up the inside of the thighs? Is he dragging his tail, or is it functioning normally? You can do most of these tests at home, especially since your partner is a vet tech, she should know the basic neurological tests. Is he pooping ok?
