I really like to stretch out in funny positions. Humans call doing this type of thing “yoga”, so I guess I’ll call it “cat yoga”. My favorite pose to lay on my back with my belly fur pointing up and my paws in the air and then stretch out as long as I can and occasionally flop around from side to side.
Doing this on the edge of the couch or from atop my perch is too dangerous, though. as I have a tendency to miscalculate the amount I can flop around without falling off.
