David: yeh? what?
Me: Right, if you get a cat yeh? and you name that cat Mouse.. right. then that cat, right, will own your mouse pad.
Me: she guards it with her teeth! she *owns* the mouse pad!
David: Mum, don't you understand? When you have a cat, everything belongs to her.
Me: I did not know that.
David: Cats are like that, Mum. Dogs have owners, cats have staff.
