What does each box contain?

Each litter box contains a bag of premium cat litter in a heat-sealed bag, which is designed to last a month for one cat. We use a new technology that coats the plastic onto the cardboard, to provide our members with a leak-proof litter box. Two side rails are also included for support. The whole system weighs around 9 pounds (Corn & Wheat, Diatomite, Fine-Grain Silica, Organic Soy, or Silica) or 16 pounds (Clay).
