Why do cats rub against people’s legs?

By rubbing against the owner’s legs, the cat marks the owner with its own pheromones, demonstrating its trust and love. This is also a way of attracting attention and showing that the cat misses and wants affection.
Cats are excellent manipulators, but hypocrisy can not – immediately show dissatisfaction if they do not like something. For example, the four-legged can refuse food for a few days, if they want something tastier.
