They seek you out and choose to be near you
They slow blink at you
They rub their head or body against you
They knead you with their paws
They purr when they are with you
They follow you from room to room
They show their belly around you
They bring you toys or other “gifts”
They groom you or lick you
They sleep on or near you
They greet you when you come home
They expose their tail upright with a relaxed tip
They allow gentle petting and stay close
They meow or chirp at you more than others
They make and maintain eye contact without tension
