"Having grown up with cats, I've never really had a problem with open litter boxes with tracking around them in a secluded corner of the house. It was just part of life and our family cats were worth it.
However... when I grew up, got a job, and moved into my first and current itty-bitty condo, that litter box makes much more of an impact on the home. I found myself spending way too much time keeping the area clean, and my cat can kick it up!
So this to me was genius. It costs a bit more than your standard litter box, but it is worth every cent. Kitty can kick all he wants and so far I've had nary a spill. He also likes the fact that it is one more thing to hop up onto. It's easy to clean and the larger liners fit very nicely."
