Dini and Nick Petty, the mother-and-son team behind the redesigned “Best Cat Litter Box Ever Made” a.k.a. “The Litter Box Reinvented” promised cat guardians an aesthetically pleasing litter box that takes seconds to clean, “with no mess or hassle” since people “love their cats but hate dealing with their litter boxes.” Made up of three stacking sifting trays, cleaning the litter box involves lifting the top sifting tray to separate the waste from the clean litter. Then you turn that tray 180° and place it at the bottom of the stack and voilà, you’re done. The way the Luuup works is anytime two sifting trays are together they form a solid tray. The three identical slotted trays together create ” a perpetual sifting loop,” thus the name (and why ‘loop’ is spelled with three ‘u’s. The promise? “You’ll never have to scoop again. No more wasting cat litter, simply top it up from time to time.” -  -  Its was the most-funded pet product ever in the histories of both Indiegogo and Kickstarter, raising $2,705,975 U.S. on Indiegogo and $375,000 U.S. on Kickstarter.
