  • Publication number: 20250113799
    Abstract: An animal litter box and feeder are disclosed. Animals, such as rabbits, typically have an animal litter box and an animal feeder. The litter box disclosed is a multi-layer structure including a lower layer, at least one middle layer, and an upper layer. The lower layer is more rigid than one or both of the upper layer and the at least one middle layer, and composed of different materials than one or both of the upper layer and the at least one middle layer. For example, the lower layer may be rigid and composed of hard plastic, the upper layer may be semi-rigid and composed of paper, and the at least one middle layer may be non-rigid and composed of plastic. The multi-layer configuration for the animal litter box may be used in combination with an animal feeder in order to provide a combination animal litter box and feeder.

  • Publication number: 20220217938
    Abstract: Animal bedding, such as for a guinea pig, is disclosed. The animal bedding comprises a main section and a pocket. The main section includes a top layer, a middle layer, and a bottom layer. The top layer is hydrophobic, the middle layer is hydrophilic and at least a part of the bottom layer is hydrophobic. The top layer, the middle layer and the bottom layer are attached to one another, such as via stitching along a perimeter of the main section. Separately, the top layer and the middle layer are attached to one another, such as in an interior of the main section, to form quilting in the main section. The pocket, which is attached to the main section, allows the guinea pig to burrow therein.
