An anti-litter spreading and containment device comprising in combination:
- a. a substantially rectangular top tray compartment;
- b. a substantially rectangular bottom tray assembly;
- c. a granular material on the bottom of the top tray compartment;
- and
- d. a fence surrounding almost completely the top of the top tray compartment except for a space in the fence for the animal to enter and exit:
- and wherein said top tray compartment possesses a bottom configuration consisting of a multiplicity of V-shaped valleys and inverted V-shaped hills, the bottom of said valleys possessing a multiplicity of longitudinal holes, said bottom capable of supporting the granular material in which that cat waste is to be deposited, the longitudinal holes in the bottom valleys being of sufficient number and size to permit passage therethrough of the cat's urine but also being sufficiently limited in size so as to be capable of supporting most or substantially all of the granular material which is placed atop some without permitting passage through the holes of said bottom valleys;
- and wherein said bottom tray assembly possesses aeration openings in its sides and in at least one of its ends to assists in evaporation of the cat's urine deposited upon the granular material contained in said top tray compartment.
