1. Territory Marking: Cats often rub their faces on objects to leave their scent behind (this is called bunting). This is done through small scent glands around the mouth, chin, face, ears, and neck. Bunting is seen more frequently in male cats than in female cats. Bunting is often done to cover up scents left behind by other felines.
2. Anxiety Relief: Spreading their scent around can make cats feel more comfortable if they’re in an unfamiliar environment.
3. Affection: Cats not only rub their faces to leave their scent behind, they also sometimes do it to pick up other scents. They might greet their owner this way as a sign of affection.
