Why do cats roll over on their backs?

When a cat feels frisky, scratchy, or has a need for a nice stretch, they will roll onto their back. Meowing, rubbing the head against the ground, and purring can occasionally be heard in addition to rolling. Regardless of the cause, rolling on the back is frequently an indication that your cat is feeling well. When a cat rolls over, it usually indicates that it feels secure and may even desire your attention.
