ABSTRACT:
A circular litter box having a scoop removal remounted in a scoop holder which is pushed around the sidewall of the box to scoop the box. The mounting mechanism for the scoop causes the scoop to assume a relatively vertical position during scooping, to minimize formation of a wave of litter in front of the scoop as it is rotated, but causes the scoop to assume a more horizontal position as the scoop is removed, so the collected waste will not spill from the scoop during removal.
