We call it “happy cat” when our cats do this to us. It’s a thing that kittens do when they’re nursing–probably why it’s also called “ecstatic kneading.” They only do it if they’re fond of you.
If you thought this might’ve been a stuffed dog, that’s OK: he doesn’t move a muscle until the very end. I guess he’s fond of the cat, too.
I could almost fall asleep watching this. Soooo cozy….
That’s the general idea.
