I came home the other day and the kittens had disappeared from the box. I wasn’t worried; it’s a small room and I’d purposely barricaded the closet. She’d just taken them all out of the box and put them on the floor (!) behind it. In the process, Quince had lost his collar.
I picked them all up and put them back in the box. Jasmine moved Bee Balm out again. I put him back. She took him out again. I put him back and rearranged things so there wasn’t really a place behind the box. She took out Quince (I think) and moved the box to create a space!
I capitulated. I took the box away and put a nice big, old, duvet cover under the desk with rolled up towel walls on either side. Jasmine was very happy!
