Mama does this to us and thinks its funny

Pinky here.
Yes, Mama does this to us. She calls it "the Move the Cat Game". I don't see what's so funny about moving us around while we are sleeping or whatever. I mean, I'm in the bed and just waking up, and she'll come in and pick me up and put me on the sofa, then move someone else, say, V'lu, who was on the rocking chair, to the bed where I was (in the exact same spot), then move move Ellen to the rocking chair where V'lu was. She giggles a lot when she does this.
I, for one, don't get it.
I'm not sure about the others.

Siiiigh,
Pinky
