She has a mind of her own. She chooses where she would like to squeeze into. This time it was a plastic basket measuring only 10 by 6 by 4 inches. I don't know how she manages it.
We were clearing some things, spring cleaning and she found a new place to sleep. When she does, she is obsessed with occupying the space fearing that it would be taken away or someone else (e.g. Umi) would take over.
