Bests & Worsts Reviews from Amazon

[Update - Original and 1st addendum below] Still having a wonderful experience with this litter box. It is the largest litter box I've been able to find, and it has not malfunctioned in any way yet! The attachments between the lid and the bottom part are still strong, the attachments between the lid and the filter on the roof are still strong, and nothing has disconnected from anything else. I am very pleased. [Addendum - Original below] This box is also awesome to scoop. The bottom half of the box is a little bit curved, so there are no crevices for stuff to get stuck in. It's also pretty huge. [Original] I've only had this litter box for maybe a day, so I can't say much about its durability or the specifics of its functionality (yet). However, one thing that I am compelled to comment on is its opening (the doorway). There are essentially three options: 1) Leave the swinging door on, so it's pretty much completely covered (which, to me, sounds mean because wouldn't the box fill with dust as the cats bury/dig? I can't imagine that's good for their lungs!) 2) Take the door off, but leave the front part of the ceiling on (the part with the filter) - This is basically a covered box with a door opening, or 3) Take the door off, AND take the front part of the ceiling off, which makes the box something like a combination of a covered box and a high-sided box The third option is ideal for me - it's exactly what I was looking for in a litter box! My cats do a lot of digging and burying, which causes litter dust to fly all over the place. This means I need a box with AT LEAST high sides. However, a covered box is better for my home because it means that I can dictate from what angle the cats enter - this allows me to position the box in a way that makes them HAVE TO walk over their litter-dust-collecting carpet when they leave the box. This way, they don't have the option of jumping over the carpet and bringing their poopy paws into the living room and getting litter dust all over the furniture. This box is the best of both worlds - high sides, but not a closed box that basically leaves them to breathe in a tiny room full of dust every time they use the restroom. In a few days or weeks, I might update this review if anything new comes up!
