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.

Description

BACKGROUND OF THE INVENTION

A strayed cat of yellow and white color used to hide at the fence and hedge of my house. None of my neighbors knew to whom it belonged. One day I fed it with some barbequed meat; and from that day on we became very good friends. Almost every day it would wait early in the morning at the side door of my patio for me to feed it with any left over. I knew it was a very diligent cat since it often brought along some small animals it caught. The cat became so contented with the arrangement, it just stayed around leisurely and happily cleaning itself all day long. I had never wanted a pet, but then I let it come into the house for visits. To my surprise, in an afternoon visit, the cat gave birth to two little kittens. The cat guarded the kittens day and night, and would leave the house only when it had to relieve itself. Therefore, I started to feed it with canned cat food. One day, about one month, after the birth of the kittens, I was alerted by the constant crying of the cat, and I discovered that it had tried to swallow the excrement from the kittens in order to maintain the cleanliness of the house. I was so moved by the cat's act, I quickly provided the cats with a sanitary litter box. It has been such a chore in having to clean the litter box daily in order to remove the feces and to eliminate the smell. Thus, I realized the problem and have developed the method and device of the present invention for providing a means for removing the house pet's excrement for maintaining the sanitary and clean environment in the house.
