Cats were never domesticated. They just realized life was easier if they had human companions, who protect them and feed them. Originally this feeding was in the way of attracting mice that the cats could catch, but times have changed when it comes to their diet. Still many cat behaviors haven't changed since then and it can really help for you to take this into account when setting up a space for them. 

     Our journey to the ultimate litter box began with our first cat Momo, who loves to dig and dig and dramatically jump out of the litter box. All of which was causing a small beach to form around the litter box. We tried using covered litter boxes, but one of our other cats made it very clear she was not a fan. We researched to understand what we could do to help keep our space clean and our cats happy. This led us to think about what can we use to make a tall litter box without constraining our cats.
