An animal litter-box including granular-material-housing, having a window opening formed in the front side of the granular-material-housing, allowing an animal to walk in and out of the granular-material-housing. The window opening includes an upper edge, a lower edge and two side edges. The animal litter-box further includes a granular-sifting-apparatus, having a container body, and a litter-scooper disposed inside the upper portion of the container body. The litter-scooper includes a scooper container body, wherein sifting-openings are formed at the bottom and optionally, at the lower sides of the scooper body. The granular-sifting-apparatus further includes a paws-sifter, disposed on top of the litter-scooper, for the animal to step on when going in and out of the granular-material-housing. |

1. An animal litter-box (100, 200, 300) comprising:
a) a granular-material-housing (110, 210, 310) having a window opening (118, 218, 318) formed in a front side (111) of said granular-material-housing, allowing an animal to walk in and out of said granular-material-housing, said window opening having two side edges and a top edge and a width (Wex) measured between said side edges: b) a limiting-door (150, 250), wherein a limited window opening is formed between side portions of said limiting-door, said limited window opening having a width (Win); and c) a granular-sifting-apparatus (120) having a width and comprising:
i. a container body (122) having a bottom;ii. a litter-scooper (140) disposed inside an upper portion of said container body and comprising a scooper body (142) having a bottom, wherein sifting-openings (144) are formed at said bottom of said scooper body and optionally, at lower sides of said scooper body; andiii. a paws-sifter (130), disposed on top (148) of said litter-scooper, for the animal to step on when going in and out of said granular-material-housing, wherein said window opening includes an upper edge, a lower edge and two side edges; wherein said granular-material-housing contains granular material up to a preconfigured level and, upon usage by the animal, possibly waste aggregates; wherein said limiting-door narrows said width (Wex) of said window opening of said granular-material-housing to be less than or equal to said width of said granular-sifting-apparatus; and wherein said limiting-door is operable to move inwardly only with respect to said granular-material-housing; wherein said width (Wex) of said window opening of said granular-material-housing is larger than said width of said granular-sifting-apparatus; and wherein said granular-sifting-apparatus is pivotally connected to said front side of said granular-material-housing, allowing transfer of granular material from said granular-material-housing to said granular-sifting-apparatus and from said granular-sifting-apparatus to said granular-material-housing. |
