US Patent:

60559357, May 2, 2000

Filed:

Aug 26, 1999

Appl. No.:

9/383672

Inventors:

Eric M. Engel - New York NY

International Classification:

A01K 2900

US Classification:

119170

Abstract:

In an exemplary form, the invention provides a liner for a cat box cover designed to rest on a cat box bottom. The liner comprises a sidewall for lining a substantial portion of a sidewall of the cover otherwise exposed to cat urine during normal operation. The sidewall comprises at least a fluid impermeable layer. The liner includes a top attached to the liner sidewall around a substantial portion of a lateral periphery of the top. In addition to the fluid impermeable layer, the liner sidewall preferably includes a sorbent layer for absorbing cat urine and preferably a claw-resistant layer for protecting the sorbent layer. The top of the liner comprises a fluid impermeable layer, and preferably also includes a sorbent layer and preferably a claw-resistant layer. Using the foregoing liner for a cat box cover together with a liner for a cat box bottom achieves significant reduction in bacteria or odor buildup in a cat box. Additionally, use of such liners for the cover and bottom typically eliminates the need for routine cleaning of the cat box itself.

Abstract:

In an exemplary form, the invention provides a liner for a litter box cover designed to rest on a litter box bottom. The liner comprises a sidewall for lining a substantial portion of a sidewall of the cover otherwise exposed to pet waste during normal operation. The sidewall comprises a fluid impermeable layer and an aperture for access by a pet. The liner further comprises at least one fastener for being held in position relative to the cover. The liner may include a top comprising a fluid impermeable layer attached to the liner sidewall around a substantial portion of a lateral periphery of the top. In addition to the fluid impermeable layer, the liner sidewall preferably includes a sorbent layer for absorbing pet urine and preferably a claw-resistant layer for protecting the sorbent layer. Using the foregoing liner for a litter box cover together with a liner for a litter box bottom achieves significant reduction in bacteria or odor buildup in a litter box. Additionally, use of such liners for the cover and bottom typically eliminates the need for routine cleaning of the litter box itself.

Inventors:

Eric M. Engel - New York NY

International Classification:

A01K 1015
A01K 2900

US Classification:

119170

Abstract:

A liner for a cat box having sides extending upwardly from a bottom to a vertical height. The liner comprises a bag for placement in the cat box. The bag comprises a bottom portion for lining the cat box, and a contiguous top portion. A fluid-impermeable layer is placed within the box, located within the bottom portion of the bag and bonded to the bag. A sorbent layer is placed above the fluid-impermeable layer. A claw-resistant layer is placed above the sorbent layer and affixed to the fluid-impermeable layer so as to stiffen the affixed layers, whereby they tend to stay in place in the cat box. The top portion of the bag drapes over the sides of the box for a drape length and provides ballast for helping the liner to stay in place.
