The Luuup Litterbox is an example of what great things can be accomplished through crowdfunding! Backed by over 14,000 people on Kickstarter, Luuup is the #1 pet product in Kickstarter history. It's not difficult to see why, the innovative sifting and stacking design makes litter box cleanup and maintenance a breeze, and can we also mention how stylish these are? You can check out this diagram or head over to the Luuup website to see a demo video of how the system works. The litter box game has officially been changed!
