## Abstract

A pet litter tray enabling easy access, organization, and cleaning comprising a tray and an interchangeable divider. The tray comprising a base, a first sidewall, a second sidewall, a back wall, a front wall, a pair of receptacles, and a lip. The first sidewall, the second sidewall, the back wall, and the front wall extending upwardly from the base, defining an interior compartment. The interior compartment comprising a food area and a waste area. The pair of receptacles extending inwardly from the first and second sidewall, configured to slidably receive the interchangeable divider. The interchangeable divider comprising a flat planar body including a top end, a bottom end, a front surface, a back surface, a panel side wall, and one or more holes extending entirely through the front surface to the back surface. The interchangeable divider defines the waste area and the food area when attached to the tray.

## Claims

### Claim 1

A pet litter tray, comprising:
a tray including a base, a first sidewall, a second sidewall, a back wall, a front wall, and a first lip, the first sidewall and the second sidewall interconnect the back wall and the front wall, the first sidewall, the second sidewall, the back wall, and the front wall extending upwardly from the base defining an interior compartment, the interior compartment comprising a food area and a waste area, a pair of receptacles extending inwardly toward the interior compartment from the base or either of the first sidewall or the second sidewall;
an interchangeable divider configured to selectively attach to the tray thereby dividing the tray into multiple sections, the divider comprising a planar body including a top end, a bottom end, a front surface, a back surface, a panel side wall, and a hole, the front surface substantially parallel to the back surface, the panel side wall extending substantially perpendicular between the front surface and the back surface, the hole extending entirely through the interchangeable divider from the front surface to the back surface;
the pair of receptacles configured to slidably receive the interchangeable divider, the interchangeable divider defining the food area and the waste area when attached to the tray, the food area configured to receive and house animal food and the waste area configured to receive and house pet waste; and
a removable floor plate comprising a proximal end, a top surface, a bottom surface, a plate side wall, a plurality of beams, and a plurality of apertures, the top surface substantially parallel to the bottom surface, the plate side wall extending substantially perpendicular between the top surface and the bottom surface, the plurality of apertures extending entirely through the floor plate from the top surface to the bottom surface, the bottom surface including the plurality of beams, the floor plate further including a first corner, a second corner, a third corner, and a fourth corner, wherein the first corner and the second corner are adjacent to the proximal end and the third corner and the fourth corner include an indent configured to engage the pair of receptacles.

### Claim 2 (depends on 1)

The pet litter tray of claim 1, wherein:
the first sidewall and the second sidewall each include a first portion adjacent to the front wall and a second portion adjacent to the back wall, wherein the first portions each include a height smaller than the second portions;
the back wall includes a height substantially equal to the interchangeable divider when the interchangeable divider is attached to the pet litter tray;
the front wall includes a height substantially equal to the height of the first portions of the first sidewall and the second sidewall.

### Claim 3 (depends on 1)

The pet litter tray of claim 1, wherein the first sidewall, the second sidewall, the front wall, and the back wall are substantially the same height, the front wall includes a first opening for pets to access the interior compartment.

### Claim 4 (depends on 3)

The pet litter tray of claim 3, wherein:
the pet litter tray further includes a lid comprising a roof, a third sidewall, a fourth sidewall, a closed sidewall, an open sidewall, and a second lip, the third sidewall and the fourth sidewall interconnect the closed sidewall and the open sidewall, the third sidewall, the fourth sidewall, the closed sidewall, and the open sidewall extend downwardly from the roof, the second lip extends outwardly substantially perpendicular to a bottom end of the third sidewall, the fourth sidewall, the closed sidewall, and the open sidewall;
the third sidewall, the fourth sidewall, the closed sidewall, and the open sidewall comprising substantially the same height, the open sidewall including a second opening substantially the same width as the first opening of the front wall.

### Claim 5 (depends on 4)

The lid of claim 4, wherein the third sidewall, the fourth sidewall, the closed sidewall, and the open sidewall extend downwardly substantially perpendicular from the roof.

### Claim 6 (depends on 4)

The lid of claim 4, wherein the third sidewall, the fourth sidewall, the closed sidewall, and the open sidewall extend downwardly at an outward angle from the roof.

### Claim 7 (depends on 4)

The pet litter tray of claim 4, wherein:
the tray comprises wood, plastic, stainless steel, ceramic, polypropylene, paper-based material, disposable material, or an equivalent material;
the interchangeable divider comprises wood, plastic, stainless steel, ceramic, polypropylene, paper-based material, disposable material, or an equivalent material;
the pair of receptacles disposed on the base, the lid, the sidewalls, the front wall, the back wall, or any combination thereof;
the base is sloped and may include grates.

### Claim 8 (depends on 1)

The pet litter tray of claim 1, wherein the pair of receptacles are disposed on the base at the junctures between the first sidewall and the second sidewall.

### Claim 9 (depends on 1)

The pet litter tray of claim 1, wherein the first lip extends outwardly around the perimeter of the tray, substantially perpendicular to a top end of the first sidewall, the second sidewall, the back wall, and the front wall.

### Claim 10 (depends on 1)

The pet litter tray of claim 1, wherein the bottom end of the interchangeable divider is positioned adjacent to the base when attached to the pair of receptacles, such that the divider completely separates the food area and the waste area, thereby preventing the food and waste from intermixing.
