2.When he rolls on his back.
When your cat rolls on your back, it’s not to make you look good. It’s simply because he’s comfortable with you. And not only, he feels confident but more he feels loved and protected thanks to you because in the end when he is on the back, they are defenseless and therefore allows himself to let go because he knows that as long as you are there, he is not risking anything. So lowering your guard in front of you is not a problem for him!
