ABSTRACT:
A pet litter box includes an elongated housing having a first end wall and a second end wall. The housing further includes a sidewall extending between the first end wall and the second end wall. The litter box also includes a base supporting the housing for rotation about a longitudinal axis. The first end wall of the housing includes a first end wall aperture shaped and dimensioned for the passage of a pet therethrough, the first end wall aperture being offset from a central longitudinal axis of the housing. The housing further includes a grate and a dividing panel respectively extending between the first end wall and the second end wall of the housing. The grate includes a first edge which remains in contact with an interior surface of the sidewall to define a grate/sidewall junction and the dividing panel similarly includes a first edge which remains in contact with the interior surface of the housing to define a panel/sidewall junction. The sidewall further includes an elongated sidewall aperture positioned adjacent the panel/sidewall junction such that the dividing panel is positioned substantially between the grate and the sidewall aperture. In use, rotation of the housing causes litter within the housing to move toward the grate, the grate defining a barrier preventing litter waste from passing therethrough and into a reservoir defined by the dividing panel and the interior surface of the sidewall such that continued rotation of the housing causes the litter waste to ride over the grate and dividing panel toward the sidewall aperture where the litter waste exits the housing.
