Puppies and small dogs that cannot get outside all day need somewhere to go indoors, and a tray with grass on top gives them a surface that feels like the real thing. It also saves buying and binning pads.

It has three layers. The top is synthetic grass, under it sits a removable plastic drainage grill, and the base is a collection tray that catches liquid and holds up to 1 gallon. To clean it, you rinse the parts with warm soapy water. It measures 46 x 33 x 5 cm, and one potty tray is supplied.
