An apparatus for retaining a liquid-absorptive sheet or pad for collecting pet wastes includes a base member and a securing member. The base member has a bottom layer and a continuous upstanding wall, which define a reservoir. The securing member includes an upper surface and two depending legs for receiving the upstanding wall of the base member. The two depending legs are flexible in directions toward and away from one another so as to form a compression fit between the base member and the securing member. The absorptive sheet is removably secured at its periphery between the base member and the securing member at least at three peripheral areas of pressure contact.

[ I claim:] [1.] An apparatus comprising:a liquid absorptive sheet;a base member having a bottom layer and a continuous upstanding wall, said bottom layer and said upstanding wall defining a reservoir, said upstanding wall having an interior vertical side and an exterior vertical side connected by an upper wall; anda securing member comprising an upper surface, an interior depending leg, and an exterior depending leg for receiving said upstanding wall of said base member, said interior and exterior depending legs being flexible in directions toward and away from one another so as to form a compression fit between said base member and said securing member, said absorptive sheet being removably secured at its periphery between said base member and said securing member,wherein said securing member and said base member establish at least four areas of peripheral pressure contact along the periphery of said absorptive sheet, a first area of peripheral pressure contact being defined by said securing member forcing said absorptive sheet against said bottom layer of said base member to hold said absorptive sheet flat against said bottom layer of said base member, and second and third areas of peripheral pressure contact being defined by said absorptive sheet being sandwiched at areas between said interior vertical side and said interior depending leg and between said exterior vertical side and said exterior vertical leg.
