Spacious but Just Right!
The picture does this litter box "No Justice" at all this sucker is huge. But it's the perfect size for Tommy, he has enough room to move around in it. When he throws the litter it does not go outside the box. It's a perfect size for him because he's at 12 lb cat. The litter box itself doesn't smell but the litter that I'm using which is tidy cat works really well there's no scent to the letter and it holds the smell from him using the bathroom really really well. It's easy to scoop the poop out of the litter box because it is enormously huge but it is very functional. Aside from it being very bulky it looks nice. I feel like it's very sturdy and very easy to use and maintain.

Perfect for multiple Cat household
As a multiple cat household I've been looking for a cat box that works for my senior cats ( Cooper, Chupacabra & Buddy) as well as my rambunctious teenagers ( Mimi & Brambles ) I like the height of the cat box and now 90% of the litter stays inside too, there also no accidental over-spray if ya know what I mean. All the cats are able to get in and out easily with no stumbling even for my 11year olds. It was very easy to put together, the delivery was good and the packaging very sturdy. I bought it based on the price value and the size, which didn't disappoint. Now for the dirty side. Cat litter is yucky, we're all looking for the nicest, easiest way to clean our cats little cat boxes with ease and without the smells and nasty pee or poo unable to be disposed of properly. I believe it all comes down to a good reliable cat litter that ticks all the boxes. Removes smells, easy to remove from litter box, little to no dust and most of all the cats will do their business without fuss or complaints. With the new littler box I thought "why not try a new litter" (bad decision) I ended up quickly ordering my all time favorite to replace the one I thought would be perfect. One of the reasons I switched back is because the cat litter that was supposed to be a clumping littler actually was sticking to the plastic bottom making it almost impossible to.remove the " wet " litter. Ugh never give up on your favorite go to cat litter even if the price changes a wee bit. The Hardball clumping cat litter is definitely on the subscribe & save list because I know it works with the littler box without sticking, it smells nice and the cats are happy. With 5 cats I do have other 2 smaller litter boxes in other locations, if I had the space I'd definitely buy another of the larger littler boxes.

It's huge and high and keeps the litter in
Good price for a huge litter box that does prevent the litter from being tossed all around by cats that excavate the box. It does have little nooks at the entry and a lower channel around the entire interior that's not easy to scoop, but found an old scoop with a rounded corners that gets the job done. So it's easy enough to scoop and keep clean. Bigger boxes really are better. I have two cats and wonder why I never thought to buy bigger before. The high sides are a selling point as well.

Best litter box ever once you find the solution to its design flaw...
Overall, this is the largest litter box on the market for cats and includes sides to help block their pee! Large cat owners need more access to larger litter boxes that won't break the bank. I've looked everywhere locally and online. I'm on my second one ordered since we wanted one upstairs and one downstairs for our large cat. He took to using it right away. I like that it immediately produced very little litter spillage on my floors! This was a huge issue I was looking to solve. A design flaw in this product as others have shared is that sometimes when the cat pees, their pee goes through the crevice of where the lid sits on the bottom box. This produces pee on the floor and makes you have to check the box more frequently and clean the mess. Disappointed that I have to fix a design flaw (all boxes have them and hard to avoid cracks between the top and bottom as this is the design that is needed to be most beneficial and provide ease of access for the owner) but a solution to this problem that doesn't cost too much and isn't too sightly is to use office clips to clip the top and bottom together. This creates a nice solid closure and leaves no room for pee to sit. This explains my 4 stars rating instead of 5 stars. You either leave the clips on all the time and scoop out the litter box or remove the clips each time you change the litter. Other than that, this litter box is one of our favorites. Treating it with care, I believe it will last us a while. Packaging both times arrived undamaged and received a clean, unused product. See photo of my invention. Hopefully, it can help you too! :)

It's great for bigger cats
I can not recommend this enough! I have 6 cats and they ALL love this litter box. My 15 year old has arthritis and she's been having some issues staying in the box, so I decided to try a bigger option to see if that would help her. It's been 2 weeks now and she's only had one accident (and it was solid so less problematic than any other option) It's so large and somehow fits perfectly in the same spot we had the last one in. This is a very roomy litter box. If they wanted to, 3 of my cats could comfortably be in here simultaneously, see picture. Dresden is a long haired domestic, he is 13lb and barely takes up a corner! Lid and ease of scooping. The lid doesn't clip on as strongly as I'd like, it just kind of rests on the base, but I haven't had any issues with it so far. I'll update if that changes. I will say that most of our litter boxes are fully covered lids, so being able to just lean over and scoop this one out is so much easier. Value for money. My friend got a similarly sized box (although a bit smaller) and she paid almost $60 just because it has a side entrance. I am very pleased that this was less than $40, I think it was a bargain.

Big Litter Box
I have a male cat who still likes to spray things (even though he is neutered). I bought this litter box to keep his spray from going everywhere (mostly the walls). It works great! The spray does get on the sides, but not on my walls. Much easier to clean. I have another cat, and she has her own corner to use. It is bigger than your average litter box. I didn't have the space for it in the laundry room. So, measure your spot and make sure it fits. You'll enjoy this knowing your walls are safe.+

Problem solving litter box
This is a fabulous litter box. It is large enough that both of my cats can use it. When they used it before, one of them consistently would miss the box. This box has solved the problem. It has very tall sides so that everything stays in the box. It was a reasonable price as well.
