Cat sleeping on its back means that the cat is very relieved about the current environment and has great trust in the owner. This is a sign that the cat is very comfortable. Cats who like to belly-turn are probably cats that grew up in happiness, have never suffered hardship, are full of goodwill towards the world, and have no defensiveness. ​​​​​​

If the cat curls up its entire body, wraps its tail around its body, and tucks its little head into its chest, then the cat may feel a little cold at this time. It is also possible that the cat does not trust the surrounding environment that much, and this posture is to protect itself.

When cats sleep in a box, they seek more security. The small and enclosed space in the box will make the cat feel safe. In a multi-cat household or an environment with children at home, cats choose to sleep in a box so that they can have a good sleep without being disturbed.
