At first, I was a little unsure at paying so much for a litter box (even on sale), but my two gatos preferred the Flip over their Booda dome box. The Flip is stylish, well made and quite sturdy for my big boys. And there has been less dust and tracked litter to pick up. The cardboard liners truly do last a month (or a little longer if one is vigilant about scooping). I love the liners as I don't have to worry about odors saturating the plastic. Lastly, though not least, the flip-top cover makes it a breeze to scoop out used litter and solid waste. I'm already budgeting for another box!
