Be less wasteful when disposing of your fur-tastic feline’s waste. The Ferplast Ariel Hooded Litter Box is a covered litter box that features two bases—one closed and one with a sieve to separate dirty litter from clean， unused litter. To remove the old litter， simply lift the perforated bottom and sift—leaving clotted litter destined for the garbage in the sieve—and saving the usable litter in the second standard bottom. This super easy system avoids litter waste while maintaining a comfortable， clean and dry place for your cat to go. Made of sturdy plastic， comes with a dark flap door and a has cover with handle for easy transport. To ensure the sieving system functions properly， please use fine-grained litters like sand and avoid coarse-grained gel litter or chipboards.
