Abstract:
1. A collapsible animal litter pan comprising: a. a foldable litter pan having a polymeric surface on a bottom floor contacting surface and a top surface, said polymeric surface being immune to animal urine soaking; b. said foldable litter pan being provided with a plurality of expandable hinges adapted to collapse and expand said litter pan in an accordion configuration along a transverse axis, said hinges intersect said bottom floor contacting surface and said top surface of said litter pan and adjacently intersect and interrupt said side walls to form hingedly connected segments separated by fold locations flush with said bottom floor contacting surface; c. said bottom floor contacting surface having a plurality of friction generating rubberized pads; d. said top surface having shallow sidewalls for locating and stabilizing a urine absorption sheet fixedly up-right and adjacent to said top surface; e. a urine absorption sheet comprising a liquid impervious polymeric bottom layer, a urine absorption layer and a top liquid permeable porous layer, and said top and bottom layer being operative to constrain said urine absorption layer; f. an adhesive coating applied to said bottom layer of said urine absorption sheet; whereby said adhesive coating located on said bottom layer of said urine absorption sheet removably adheres to said top surface of said foldable litter pan for enhanced stability of said urine absorption sheet, animal urine is substantially completely absorbed by said urine absorption sheet, animal solid waste is retained on said sheet, and a user discards a soiled urine absorption sheet and adheres a fresh urine absorption sheet onto said top surface of said foldable litter pan for future use.
