The Rabbit Litter Box is made of high-quality BPA-free plastic that is soft and durable. The edges of the mesh are rounded and curved, which prevents your pet from being scratched by them. The smooth guardrails on both sides of the litter box prevent urine from splashing out of the litter box. The special design is also stain and odour resistant, making it easy to clean. The two buckles on the back of the litter box keep the tray in place.
