Wim got caught out this morning. The whole family was in the Ensuite when he needed to get in for food and cleaning. Mitsy looked to be in good place, so he did her food first. Then waiting until she was done, did the water from the other end, and then waited again. Then he wanted to do the litter but she was still in the Ensuite and he decided to stick out his hand to her. Quietly, but she did not appreciate it and pawed him. No claws, but enough to make him retreat and get out of the way.
On the cat cam I saw that she has settled down in Basecamp around 8am so I decided to do the litter box myself.
It went fine, no sign of annoyance.
