This creates a kind of mat,It includes: a knockout layer and a poly- layer of sand,The knockout layer has the drop-hole of a plurality of polygons,The peripheral annular of the drop-hole is arranged with plural convex body,The convex body is that drops has pointed and circular two end,The peripheral ring of the knockout layer around being coated with one first frame,The appearance profile of the poly- layer of sand is identical as the knockout layer,The peripheral ring of the poly- layer of sand around being coated with one second frame,Second frame and first frame are facing,Second frame makes the poly- layer of sand form a concave accommodating space in face of an inner face of the knockout layer. Ram's horn is thereby provided and is grabbed and does and the cat litter on pawl is made to fall aggregation what accommodating space, facilitates collection cleaning to keep room clean.本創作一種踏墊，其包含：一落砂層及一聚砂層，該落砂層具有複數個多邊形的落砂孔，該落砂孔的外周環形排列有複數凸體，該凸體為水滴狀具有尖形及圓形的二端，該落砂層的外周環繞包覆有一第一邊框，該聚砂層的外形輪廓與該落砂層相同，該聚砂層的外周環繞包覆有一第二邊框，該第二邊框與該第一邊框相面對，該第二邊框使該聚砂層面對該落砂層的一內面形成凹狀的一收容空間。藉此提供貓爪抓弄並使爪上的貓砂掉落聚集於該收容空間，方便收集清理以保持房間乾淨。
