Pet waste cartridge
A waste cartridge in combination with a waste machine or apparatus that maintains waste pads for a pet owner, automatically or manually by removing and sealing soiled pads and waste and then replacing the soiled pad with a clean pad on a pet bed of the machine. The apparatus senses when a pet is using a waste pad portion and when the pet is finished, the machine takes up the soiled portion of the pad and removes and seals the soiled portion of the pad roll and the waste automatically, moving the pad into a repository for later removal and disposal of the waste cartridge when the pad roll is used up and then replacing removed pad with a new waste cartridge. The waste cartridge is comprised of a pad roll and a take-up rod attached to one end of the pad by any means such as a clip, slot or adhesive on the take-up rod. A pair of end caps on opposing ends of the take-up rod that includes a gear for attachment to a removable drive module may also be included or left off if the rod or core is directly connected to the drive module.
