pets should make themselves useful

Imagine a pet that is small, cute, requires minimal care, and vacuums the floor for you... Think robotic vacuums.

I sure won't mind owning one of these cuties for my place. Sit about and enjoy a cuppa while the cute little whiz goes about vacuuming the floor. As entertaining as watching a pet roam about while actually having something useful achieved, which in this case is the vacuuming of the floor. I wonder if the robotic vacuum comes with its own tortoise cosplay suit...
