They are all doing well. Litter box learning is slower than some litters, but perhaps some of that is from the numbers: with 6, I’m often feeding someone when I see someone else start to crouch. White Onus is especially good at running to the far corners of the room to pee. And I can’t expect Orchard to climb into the litter box, although she is good at climbing in tight spaces. A dished ramp might work for her.
