An absorbent pad is configured for receiving waste. The absorbent pad includes a base layer and a string. The base layer has a collection region surrounded by a peripheral edge. The string is slidably attached to the peripheral edge at a plurality of locations. The base layer is configured to move from an open position to a closed position. The base layer is configured to be substantially flat such that the string is disposed along the peripheral edge when the base layer is in the open position. The base layer moves from the open position to the closed position in response to sliding the string relative to the plurality of locations, whereby the peripheral edge is drawn together at the plurality of locations to form a bundle and the string is only disposed along the peripheral edge corresponding to the plurality of locations.
