Cats have been rolling on the ground because they itch or need insect repellent. Although no one can match the flexibility of the cat's body, there are still places that can't be reached, so the places that can't be reached can only be solved by external forces. Rolling on the ground and rubbing to relieve itching are all uncomfortable reactions of cats. That's why you can see the cat rubbing its back on the ground.
