发明名称 Odorless animal litter unit
摘要 The odorless animal litter box of the instant invention includes a box-like container capable of locking in place an absorbent pad structure, which includes a protective screening and a moisture impermeable liner. The protective screening is flexible and formed of strands bonded at their interstices, is substantially inert to urine and capable of withstanding the clawing action of an animal such as a cat. The sheet layer of moisture impermeable material has length and width dimensions at least equal to that of the screen. A sorbent pad is positioned between the screen and the moisture impermeable material and the screen is sealed to moisture impermeable material along at least a substantial portion of their peripheral edges.
