Smudge-Gryffindor is especially aware of me if I am in the room. He trudges all over to reach me if the enclosure is open, and contained or no, cries out until I feed him. Sometimes I get busy with the back end instead, or another kitten, or even some computer work, and he gets very ticked off.
All four are aware when they need to poop, but mostly don’t use the box yet and always need some cleaning up after. It would help if the poo was less liquid and mucusy.
