the kneading action of a cat with its paws, while sitting on a human, resulting in tiny claw pricks in the skin, similar to acupuncture. Usually performed on the chest or breast of the human, while the human is petting the cat.
I know when my cat, McGee, is content because he starts purring and performing catupuncture on me. This does not make me content!
When your kitten attacks your hand, leg, arm etc, using teeth and claws.
J: Dude! What happened to your hand? It's covered in scars.
D: I got a new kitten, she's been practicing catupuncture on me.
