  • Flush toilet for domestic pets
    Patent number: 6418880
    Abstract: Cats are generally well liked in our society. At one time cats were raised for the sole purpose for catching mice in order to protect food stuffs and for preventing the spread of deceases. Nowadays, cats are even more reverent as pets since they provide companionship to the owners. For these reasons, they are important members of our society and their well being and health are closely related to ours. The present invention provides a flush toilet for removing excrement from pets such as cats and dogs so as to preserve the well being of the environment and to reduce medical expenses due to the unsanitary condition created by such excrement if not removed.
