All of my cats knead, at different speeds, pressures, and claw extension.
My oldest, was found in a bush a few weeks old and given to me. I'm his first memory lol and I have a small amount of stomach fat that he somehow can seek out and pull on my skin.
The second oldest, I got right as she was getting weaned. She once started doing it to my damn FACE as she dozed off. Hurt like he'll and almost got my eyeball.
The other ones... only one other does it on me, the others only do it to pillows and blankets, never to people.
