Cats rub their owners’ legs for a variety of reasons. It’s one of their most important behaviors for communicating with you and bonding.

Why Cats Rub
Marking Territory: Cats have glands on their face, cheeks, and tail. When they rub your legs, they transfer their scent to you. This is their way of marking you as part of their territory and group.
Greeting: When you come home, rubbing is a way of saying “hello.” It’s a sign of joy and affection.

Attention: Cats are very smart and know that rubbing is an easy way to get their owners’ attention. It’s often an invitation to play or ask for food.
Relaxation: When cats rub, they release hormones that help them relax and feel good.
Bonding: It’s a way to strengthen the bond with you. It’s a sign of trust and affection.

What you should do
If your cat rubs against your legs, it’s a sign of affection. You can respond by petting or playing with it. It’s a good opportunity to strengthen the bond with your cat.
