Flushing litter boxes

2 models · 1 brand, ~$469–$499

Flushing boxes are plumbed in: a cold-water line in, a drain hose out. After each visit they clean the bowl and send waste down the pipe, so nothing is ever emptied. They need a spot within reach of a drain and a steady supply of the maker's own cleaning cartridges and litter or granules.
