What does it mean when a cat rolls around and rubs its head on the ground?
When a cat rolls and rubs its head on the floor, it might be trying to be affectionate with its owner, and sometimes it will meow. However, it could also be that the cat is in heat, and the owner should observe whether it also exhibits symptoms such as loss of appetite. If the cat frequently rubs its head on the floor, it's also worth noting that it might be itchy.

Cats sometimes act affectionately in front of their owners. When they do, they will expose their bellies, roll around and rub against their owners, and sometimes they will meow and interact with them.
Cats in heat will roll around and rub against the ground, and will also exhibit symptoms such as frequent meowing and loss of appetite. For cats in heat, you can choose to mate them or have them spayed/neutered.
Scrubbing on the ground can also be due to itching. When cats have skin problems, they will often roll and rub on the ground or rub their bodies against objects such as walls to relieve the itching.
