ABSTRACT:
A liner for use in a litter box or tray for cats, which is of conventional design having sides and a bottom, the liner having a plurality of flexible sieve sheets overlying a flexible impervious sheet, sheets being removeably attached to an underlying semi-rigid support, and being of such size as to overlap the sides of the litter box, the support having an attachment device for attaching the support to the bottom of the litter box, such that when litter is placed in the box over the liner packet, the sieve sheets are periodically removed to remove fecal matter by screening and aerating the litter, and lastly the impervious sheet is removed to remove and discard the litter before replacement with a new liner packet and new litter whereby the period over which litter is usable is substantially extended.
