Rolling on the Floor
Cats roll around on their backs for many reasons. However, they only do it if they’re comfortable, as showing the belly is a vulnerability to them. This motion might be used to stretch the muscles or scratch the back, but sometimes the cat wants to play.
Eye Communication
When cats stare at you, they are likely trying to get attention. However, different stares have other meanings. If they’re looking intensely, this could be a sign of aggression, so you shouldn’t stare back unless you want your kitty to pounce on your face!
