Tidy cat litter box

摘要

A tidy pet litter box having a plurality of internal screens across which the pet must traverse when entering or leaving a main basin of the litter box. An upper lid fits over a lower tray, the upper lid having a large front opening. The lower tray defines a large main basin in which litter is placed, and a secondary basin at a rear end thereof. An entrance screen mounted laterally across side walls of the upper lid extends from a lower end of the front opening substantially over the entire main basin and permits passage of a pet to a rear screen located above the secondary basin. To exit, the pet must jump up to the rear screen, then over the entrance screen which dislodges any litter sticking to its paws so that it falls back into the main basin. A method of training a cat to use the litter box by first removing the entrance screen is also disclosed.

主权项

1. A pet litter box, comprising: an enclosure defining a lower main basin sized to contain litter and a secondary basin raised up from the main basin at a rear of the enclosure, the enclosure further including a lid over the main basin and secondary basin having a front opening large enough to permit passage of a pet; an entrance screen spanning laterally between side walls of the enclosure and positioned at the front opening, the entrance screen extending from the front opening into an interior volume and below a top wall of the lid, the entrance screen having a front edge and a rear edge and a front to rear length therebetween such that the entrance screen extends over substantially the entire main basin, the entrance screen having a first portion that slopes upward from the front edge thereof adjacent the front opening, thus forming an entrance ramp and raising the entrance screen above a floor of the main basin in a rearward direction, the entrance screen further having a second portion that extends generally horizontally to the rear edge of the entrance screen; and a rear screen spanning laterally between side walls of the enclosure and positioned above a floor of the secondary basin, the rear screen extending from a rear end of the enclosure to a location approximately aligned with the rear edge of the entrance screen, the rear screen being spaced vertically below the entrance screen a height sufficient to permit passage of a pet therebetween and being suspended above the floor of the secondary basin such that any litter particles that fall through the rear screen are recycled into the litter box.
