My grandmother used to receive that of dead moles, freshly caught mice and what have you, invariably placed dead center on her pillow. She wasn't a fan of that cat before, and she didn't like it much better after. No idea why.
Growing up our family cat brought us a constant stream of rabbits, birds, and moles. It is actually a problem that nobody talks about, because cats are cute.
And I've had a fine afternoon tossing a rubber ball that would bounce all around the living and dining room in billiard-style angles, and have an hour or more of lazy returns and rethrows.
