A litter box for a domestic animal includes a box-like body equipped with an upper support wall that has a through opening, a container of a granular litter material susceptible to absorb the animal excrements, and a first tubular duct arranged below the upper wall, which is substantially extended between the upper wall and the bottom of the body, for conveying the animal excrements towards a discharge zone in the lower part of the body. The receptacle surrounds a second tubular duct inside the first tubular duct, whose upper end faces the opening and whose lower end faces the bottom of the body, and which defines an internal edge of the receptacle for the purpose of retaining a quantity of the granular material therein.

1. A litter box for domestic animals for use with a granular litter material, the litter box comprising: a box-like body having an upper wall for supporting a domestic animal,a receptacle for containing the granular litter material susceptible to at least partially absorb animal excrements,a first tubular duct arranged below the upper wall, for conveying the animal excrements towards a discharge zone arranged in a lower part of the body of the box, wherein said upper wall has a through opening facing the first tubular duct, and in that the first tubular duct is substantially extended between said opening and the receptacle of the granular material interposed between the upper wall and a bottom of the body, and said receptacle surrounds a second tubular duct with smaller cross section than the first tubular duct, arranged inside the first tubular duct and having an upper end facing the opening of the upper wall of the body and a lower end facing the bottom of the body, and said second tubular duct allows the fall of the animal excrements towards the bottom of the body and defines an internal edge of the receptacle for the purpose of retaining therein a quantity of said granular material, so as receptacle being placed at a distance from said opening such to allow an animal set on the upper wall to reach, through said opening, the granular material present therein. 2. The litter box as claimed in claim 1, wherein the upper wall of the body has an abrasive upper surface. 3. The litter box as claimed in claim 1, wherein the upper wall of the body is removable. 4. The litter box as claimed in claim 1, further comprising a valve device arranged below the second tubular duct, in order to selectively allow a communication between a lower portion of the second tubular duct and the bottom of the body. 5. The litter box as claimed in claim 4, further comprising a main tank interposed between said upper wall and said valve device, and in communication at least with said receptacle, in a manner such that the receptacle is automatically resupplied with the granular material starting from said main tank. 6. The litter box as claimed in claim 4, wherein said valve device comprises at least one plate shutter slidably mounted transverse to the second tubular duct, between a closed configuration and an open configuration. 7. The litter box as claimed in claim 4, wherein the valve device comprises an oscillatable tab associated with the upper surface of each plate shutter, rotatably mounted around an axis transverse to the relative plate shutter, functioning as a scraping element of the granular material contaminated by the excrements and present above said plate shutter. 8. The litter box as claimed in claim 7, wherein the upper surface of each plate shutter has a transverse rib which cooperates together with the relative tab in order to keep the clean granular material separate from the granular material contaminated by the excrements on top of each plate shutter. 9. The litter box as claimed in claim 6, wherein said at least one plate shutter comprises a handle that can be grasped by an operator from outside the body for the purpose of allowing a manual movement of the shutter towards the open or closed configuration of the valve means. 10. The litter box according to claim 9, wherein said at least one plate shutter is biased towards the closed configuration of the valve means by elastic return means. 11. The litter box as claimed in claim 6, wherein said at least one plate shutter comprises a pedal connected to said at least one plate shutter by means of levers, for the purpose of allowing the movement towards the open or closed configuration of the valve means by exerting pressure on said pedal. 12. The litter box as claimed in claim 6, further comprising motorized control means adapted to move said at least one plate shutter verso the open or closed configuration of the valve device. 13. The litter box as claimed in claim 12, wherein the activation of the motorized control means is controlled by sensor means that detect the presence of excrements associated with the second tubular duct. 14. The litter box as claimed in claim 1, wherein the body is associated with a removable excrement collector that includes a drawer slidably mounted with respect to the body. 15. The litter box as claimed in claim 14, wherein said collector comprises a mouth for placing said second tubular duct in communication with said removable excrement collector. 16. The litter box as claimed in claim 15, wherein said mouth of said collector and shutters form seal closure means adapted to prevent the dispersion of odors into the outside environment. 17. The litter box as claimed in claim 15, wherein said collector is movable between a position in which said mouth is aligned with said second tubular duct and a position in which said mouth is not aligned with said second tubular duct. 18. The litter box as claimed in claim 1, wherein the body is associated with extractable legs adapted to allow bringing the body into a raised configuration, for the purpose of facilitating the removal of the animal excrements from a discharge zone at the bottom of the body, said legs being articulated to the body and having click-fit anchorage means with respect to the body, in an extracted configuration.
