They figured out what a litter box was for and were very good at it, even fluff-butt Taco. They had what was probably their first BART ride, to work with me. Once there, we found a box big enough for the litter box, warmy disc, one food dish, some towels, and a skinny box to climb and chew. I’d feed them on some paper outside the box and put them back in the box when they’d wander. They played and slept and used the litter box. Some of the sleeping was between my shirt and jacket. Taco would peek out now and then and chew on the zipper. They were very polite and met 4 new people at the office and one on BART. The office cat heard them but was not interested in meeting them.
