I've posted this (in a series) before on Cats Enjoying Their Cat Trees but it happens to have found it's way onto my desktop, so I thought I'd share it again.
D's face is rammed up against the scratcher and the rest of him is doing some kind of upside-down, fit legs wherever they'll go thing. It looks like a very silly, awkward, position to me. But hey, he was in there quite a considerable time, so what's comfy to one, and all that.
