  • Patent number: 6412442
    Abstract: Described is a device that can be used to restrain household pets or other animals, as well as to assist in potty training household pets. Such device is portable, open, and easy to clean. Specifically, the device is a lightweight base upon which the household pet is free to move with a restraining piece such as a strap in the center of the base to which a leash can be attached. The base is sloped from the center to the edge, having a gutter about the periphery of the base. The gutter combined with the sloped base allows easy clean-up of any accidents the pet may have while on the base. The described devices could be used for many different animals and not just well-known domesticated household pets.
