Abstract
A collapsible animal litter pan has polymeric surfaces that are immune to urine soaking. A plurality of hinges collapse and expand the litter pan. The litter pan has sidewalls that locate, receive and stabilize a urine absorption sheet. The urine absorption sheet has a liquid impervious bottom layer, a urine absorption layer composed of cotton, cellulose fluff pulp, commuted pulp, soft wood fine chips, or hydrophilic paper and combinations thereof, together with superabsorbent polymers and a top, liquid permeable, layer. The top and bottom layers are bonded to constrain the urine absorbent layer. An adhesive coating is applied to the bottom layer of the urine absorption sheet for temporarily adhering the sheet to the foldable litter pan for enhanced stability of the urine absorption sheet. Animal urine is substantially completely absorbed by the urine absorbent sheet, and the soiled sheet replaced with a fresh sheet without soiling the litter pan.
