The Ezi-LockOdour XL version kit uses the same odour control technology as our beloved original kit, but now with more litter tray space than ever before! Perfect for larger cats or homes with more than one cat, the XL unit when assembled measures 70cm x 47cm x 35cm. Bigger design means even more comfort for your feline friend, as well as higher walls that conceal mess in the home. Pellets will still last 1 month, when setting up your kit add both bags at once to ensure the base is covered enough.
