  • Patent number: 4098229
    Abstract: A self-contained, portable animal commode including a base with a waste holding tank and a top pivoted to the base, the top including an end vertical panel, for satisfying a male dog's natural urinating instincts, and a platform underlying a movable belt upon which the animal stands to urinate and defecate. After the animal steps off the commode, the belt is rotated forwardly to deposit waste in the tank while, simultaneously, the end panel and belt are flushed of waste. Then the belt is reversely driven to its initial position, the belt being wiped clean when moved in both directions.
