Abstract
A household animal waste collection sheet having a liquid permeable top sheet, a liquid impermeable backing sheet and an absorbent core interposed between the top sheet and the backing sheet, is disclosed. The absorbent core is formed of a pulp layer and particulate super-absorbent polymers disposed on both a top face and a bottom face of the pulp layer. This waste collection sheet has a high rate of liquid-absorption while preventing liquid from flowing backward to the top sheet. Further, the waste collection sheet has a high stiffness.
