If a cat likes to rub someone's legs, it means that the cat likes the person very much. Rubbing the legs is marking its own scent and declaring its sovereignty to other cats. The owner comes back from outside every day with different smells on his body, and the cat will want to combine these smells to prove that the environment is relaxed and safe. ​​​​​​

When a cat rubs its head against its owner, it releases pheromones, which makes the cat feel particularly comfortable. If a cat jumps on your lap and rubs its head against you, they are saying they love you.
