Say goodbye to messy liquid when you clean up after your pets! The Pee-Pod™ is a disposable tray that fits neatly inside the Pet Loo™ Pet Toilet and holds up to 2 liters of liquid waste. When your dog’s urine touches the Wee Sponge™ powder inside the tray, it solidifies into a gel, instantly trapping liquids and airborne odors. This multi-pack contains 7 Pee-Pod™ trays and will last 21-28 days. PetSafe® brand is here to help you and your pet live happy together™.
