* Rigid and Sturdy Design: These disposable litter boxes are not flimsy! Made with densely compressed 100 percent recycled cardboard pulp. Even when they're filled with heavy cat litter, they maintain their shape. * Convenient Cleaning and Disposal: Simply fill the disposable litter box with your preferred cat litter (we prefer to use them with a clumping litter), remove waste daily, and dispose litter and box every 2-3 weeks, or as needed. * Reduced Odor: Sick of your house smelling like a cat box? Great news, you can throw away the stink every few weeks when you completely change out your disposable litter box. No more scrubbing and no more stink.
