CONVENIENT: Reduce the hassle of cleaning up after pets with disposable cat litter trays. Made of leakproof cardboard, the litter box set helps reduce time and effort spent changing litter. EASY TO CHANGE: The trays can be disposed of and replaced every few weeks or as often as needed. Simply throw out the used box and litter, and replace with a brand new fresh tray. MADE OF CARDBOARD: The trays are made of 100% cardboard, making them an ideal alternative to other disposable trays. The material is sturdy yet lightweight to move around. ALONE OR AS LINER: Use as a standalone litter tray, or as a liner inside of a larger litter box. The trays are made of leakproof material, so they can be used in either scenario depending on the needs of your cat or kitten. IDEAL FOR TRAVEL: Disposable litter trays are ideal when traveling, moving, or bringing cats to stay in a temporary location such as with family or friends.
