The Litter Genie® Easy Roll refill features our beloved multi-layer odor-locking barrier technology bag that stops the sights and smells of soiled cat litter right in their tracks with some impressive newly added benefits. Easy Roll bags are perforated on a roll, allowing you to simply pull and peel off a full bag and effortlessly set-up a new one for ultimate convenience. The refill can last up to 6 months for one cat, so you won’t have to constantly worry about buying and changing refills.
