Litter box with abrasive surface

DETAILED DESCRIPTION OF THE INVENTION A litter box 10 suitable for use by domestic cats or other small domestic mammals is shown generally in FIG.
1.
Such litter boxes are usually rectangular in shape and have sides 12 and 14, ends 16 and 18, and a flat bottom 20.
They are designed to contain a scented absorbing litter material as will be described in greater detail hereinafter.
When cats use the litter box they instinctively scratch in the box to cover their waste.
The present invention provides an abrasive sheet material 22 that can be cut to fit the interior surfaces of litter box 10.
Abrasive sheet material 22 has an abrasive material 24 on the upper surface and an adhesive on the bottom surface temporarily covered by release paper 26.
In FIG.
1, the abrasive sheet material 22 is shown being applied to bottom 20 of litter box 10.
Abrasive sheet material 22 is cut at end 28 removing material 30 and cut at side 32 to remove material 34 to size the abrasive sheet material 22 to the proper size to fit on bottom 20 of litter box 10.
In some cases little or no sizing is required.
Preferably, abrasive sheet material 22 is constructed to fit the largest size litter box available and need only be trimmed to fit the bottom surface of smaller boxes.
While a single sheet of abrasive sheet material can be applied to all interior surfaces 12, 14, 16, 18, and 20 of litter box 10, it is preferable to apply a separate sheet to each of the interior surfaces.
This makes application of the abrasive sheet material easier, as a single sheet would be difficult to fit into the comers, particularly when there is adhesive on it.
Abrasive sheet material can be made large enough to produce two cut end pieces 30 and two cut side pieces 34 with the end and side pieces being large enough for application on the interior of ends 16 and 18 and on the interior sides 12 and 14.
Alternatively, the abrasive sheet material can be pre-cut in five pieces to fit a typical litter box and packaged and sold in kit form.
Preprinted cut lines may be applied to the abrasive sheet material to simplify installation
