A portable pet toilet comprising three layers a surface layer designed such that a pet is encouraged to urinate upon it, a bottom layer (shield layer) designed to prevent urine from contaminating any floor material upon which it rests, and an intermediate layer designed to absorb and retain the amount of urine that can be expected to be excreted by the pet. The bottom layer is afforded with a means for securing the position of the other two layers while allowing all three layers to be formed into a compact roll to facilitate portability.
