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. Thus, while the liners will need to be periodically changed, the cat box typically remains clean and odor-free for months.
