The Petmate Giant Litter Box offers a great solution for large cats or multiple cats. The oversized, open style also accommodates cats who do not like the confines of a hooded pan or those who require plenty of room. Constructed using a durable, odor-resistant plastic it is designed to hold large amounts of litter and features a sloped entry that allows older cats and kittens easy access. The high sides help to contain litter scatters. Can hold over 30 lbs. of litter for less frequent changes, so you can spend more time with your cat and less time on cleanup. When it is time to change the litter the side rims give you a comfortable grip whenever you need to move it. Made using 95% pre-consumer recycled plastic. Made in the USA. Due to the large size of this pan litter liners are not available.
