When I first looked at this cat tree a few years ago I wasn’t sure exactly how they would take to these half-pipe platforms, but they have really been popular with all the cats. They all like the feeling of being partly enclosed but not held, like being cupped in a pair of giant hands.
It’s good for a little touch up cleaning since there are no worries of falling off the edge. Even Julius in full wriggle display hasn’t managed it.
Of course once you clean up, you’re too tired to go and do anything but sleep.
