They do appreciate a floor-level lap for napping. Hammie is all the way through my legs and on the floor, but undisturbed. It turns out, he is not gaining weight, just yo-yoing. The others have a nice slanted groth line. They get a check-up Tuesday and I can get some advice. He IS younger than the others; he does eat and play, but always a little slower than the others. Also, I think he’s the one who has been peeing outside the box: I’ve caught him settling into the position a couple times and moved him.
Added note: just caught Gorgon peeing on my computer bag. The blame can be spread around. As can the pee.
