We have had tons of different litter boxes for our cats, Rocky & Faith…but recently moved to a smaller apartment in order to downsize and found that due to the smaller space the litter box choices we found just didnt work – they took up too much space or were too ugly or didnt keep the area clean enough in our little apartment. Then i read about the ModKat and my husband & I were so impressed we pre-ordered. The cats took to it right away, and it’s been awesome. It takes up only a small space, keeps most of the litter in the litterbox because of the roof-top access and I dont have to keep buying liners for the box! We love it and so do our cats!
