Yes, he does this almost everyday... for fun. The first time I saw him do this I totally freaked out and stood underneath with my arms outstretched, I was sure he was going to fall. But, he is a cat after all, and has proven himself to be quite skilled at climbing up and down trees. Sometimes he isn't very graceful and will even appear to stumble, thankfully, he always catches a stray branch with those claws of his. He is getting much better at it now, which is why I feel safe enough to stand back and take pictures while he does his thing.
