Don't panic when you see your cat rubbing its head against a wall or other object. It's leaving its scent to tell or signal to other cats that this is its territory and they shouldn't come near.
In addition, indoors, cats often don't get enough physical exercise, which can cause tension and discomfort in the muscles of their head and cheeks. Therefore, when cats feel stressed or tired, rubbing against a wall or other objects can help them relax and soothe their mood.
