I'm happy to say that, after the trauma of falling out the tree (see my last blog post), Doc is doing just fine. I was worried because he was limping a little yesterday but today, he's just fine. I guess he just sprained his leg a little bit when he fell out of the tree. But he's purring and walking around today. When I fed him, he jumped up on the kitchen counter and then he jumped down to the floor and basically scared me to death but he landed just fine.
I love my cat.
