LitterFree Self Washing Cat Box (21.5" x 15.5" x 19.5")
Product Description
DISC 02/06/03 LitterFree uses the power of water to dissolve cat eliminations. LitterFree is a Self-Washing Cat Box, which means that you don't have to scoop, collect, dump or flip receptacles...it automatically flushes away cat waste down the drain. Along with washing, LitterFree treats odor-causing materials by using an environmentally friendly cleaning solution. In a short time, LitterFree is dry, fresh and clean for your cat to use. Thanks to the Self-Washing concept, there is no longer a need to use a large amount of litter material in the box. One bag of washable granules is enough for your litter box to always be clean. Your home will now be a healthier, more enjoyable place for cats and people!
