Abstract
Before inserting the waste removal tray into a self-cleaning litter box that is cleaned by rolling, a user envelopes the waste removal tray within a bag, with the bag secured by a bag retainer on the litter box. After rolling the litter box, the cat excrement will rest inside the waste removal tray, atop the collapsed bag. During withdrawal of the waste removal tray, retention of an edge of the bag cooperates with movement of the waste removal tray to invert the bag and retain the cat excrement within the inverted bag. After the waste removal tray has been completely withdrawn, the inverted bag will be suspended by the bag retainer with the cat excrement inside, and the bag can be conveniently disposed of.
