The device further includes a litter tray having a removable cover and an integral shelf and tab, wherein the tray can be placed within the housing and can have pre-filled litter. A user can manually flip the litter tray via gripping the tab, causing the litter therein to move downward, wherein the shelf prevents the litter from spilling therefrom whereby the litter tray rests against the rear wall in a vertical orientation. Thereafter, the front and rear walls are manually pushed toward one another to collapse the housing via the pleats and is secured by the fastening straps.
