Abstract: A retaining apparatus for retaining a liquid-absorptive sheet includes a lower layer and an upper layer having substantially the same dimensions as the lower layer. Sandwiched between the two layers are first plurality of magnetic members arranged along the perimeter of the lower layer and a second plurality of magnetic members, opposite in polarity to said first plurality of magnetic members, arranged adjacent to the first plurality of magnetic members.

Abstract: An apparatus for retaining a liquid-absorptive sheet includes a base member, a securing member and at least one clip. The base member has a bottom layer and an upstanding wall, with the bottom layer and the upstanding wall defining a reservoir. The securing member includes an upper surface and two depending legs for receiving the upstanding wall of the base member. The absorptive sheet is removably secured at at least portions of its periphery between the base member and the securing member to hold the absorptive sheet against the bottom layer of the base member. At least one end of the absorptive sheet extends over at least a portion of the upstanding wall. The clip connects the securing member to the base member.

Abstract: 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.
