Read my review then buy it!!!
Stop thinking whether this litter box is worth or not, and just buy it!! I was looking for a newer litter box because mine had the same one for 3 years ever sense I adopted him, and a year ago i tried to change it but Instead I ended up returning two different litter boxes. So, this year comes and I’ve been updating a lot of his stuff, so I thought that maybe now they’re designing better litter boxes because the old one he had would start to smell easily and it was getting too small for him. I was doing researching and looking for a good litter box for a week, then I made a decision and purchased one for $60, once I got it, not even a week in and his urine was leaking out, and this was TRAUMATIZING!!! so I returned it, set up his old one, and kept looking for another one, I was determined. Then I stumbled upon this one, and it was half the price of the one I returned. It looked good, and seemed like nothing can be wrong with it? then I read the one-two star comments, and I was a bit discouraged but I realized those comments were mostly from a few years back, so maybe it’s better now. I finally bought it and here are the boxes it checks: - Assembly? Easyyyyyy there’s a handle on the back side, you insert it then you make sure the circles go in the holes. Once you hear a subtle click then you’re good. - Urine leakage? Noneeee, the walls are very high and it’s all one piece only the top clicks in. - Weight? Very light and the quality matches the price. - I discovered my cat likes getting in from the top from the last litter box that didn’t work out for him, so that’s why I chose this, and he lovessss it!! - it’s very spacious and private on the inside, and odor doesn't come out because of that. - Cleaning the litter? so easy!! you just take out the top, and any litter that caught between the lid you can just empty it out in the box, then scoop it out! I also use arm and hammer litter deodorizer (another product I recommend for only $4) and idk if it’s that product or the litter box itself but nothing sticks to the sides of the box and the scoop and it’s always left very clean! - Scoop? love herr! my cat takes really big poops and she does the job! - Cleaning the litter box? Easy!!! you can just throw away the litter then hose it down, and bam you’re good to let it air dry. Lastly, I want to mention that my cat always has litter laying on the outside of his box which is why I have a mat. But coincidentally, my mats are dirty because there’s urine on them and I have them put in a bag in the garage because i’ve had no time to wash them. So, when I got his litter box I just put it there without a mat, and I haven’t seen ANY litter outside of the box!!! But that’s my experience with this litter box, and i’m genuinely a happy cat mom and my cat is also very happy, so don’t think and just buy it!

Best littler box we've had
I bought this litter box on June 24, 2018, so after a year I've decided to give my review. I have a 12 year old male cat and was looking for a new littler box. I've had several cats over my lifetime (as a kid and adult) so i've tried several different litter box designs. We had been using a really large box with a lid/cover and flap door. It was getting so smelly all the time (even though we cleaned it regularly) and he would end up peeing on the sides. It seemed no matter how large the box, it was just a mess. And I mentioned the smell...well, i thought with a covered litter box, it would keep the smell in, but not so sure now. I had though about using just an open pan, but we have dog (who started to discover how to push the flap and get his head in there). Also, I wasn't keen on litter being kicked all over the floor. I went online in search of a solution. I ran across this one and read through almost all of the reviews. I decided to give it a try, and got the large one. It's been a year and I still believe this to be the best litter box i've found. He adapted really quick to the top entry. His head can stick out the top if he needs it to. He no longer pees on the sides. On top of all that, the smell is practically gone. Maybe it's the design, or the "open" top that allows odor to dissipate rather than be trapped and get worse, I don't know but i'm impressed and very satisfied. We use the Arm & Hammer Litter as well and clean at least once a week. Also, our dog isn't tall enough (or brave enough?) to get on the box and get his head in there, so that issues is solved as well. And, it get's better.... We just adopted a kitten. He's been used to the small open pans in foster care. He took to the open top easily as well. Since he's a little tyke and too rambunctious to leave out at night, we keep him in the bathroom so we can all sleep. I tried a small pan at first, but he's a kitten and likes to REALLY throw that litter around. So....I purchased the small version of this box to keep in there overnight (pull it out and put it away during the day so he uses the big one). Kittens are cute, but they can be stinky. Once again, this box comes through. And again, little to no litter scattered everywhere. The boxes are easy to use for getting the top off, cleaning, and they look nice. I got the white one with the tan/beige. I keep it in the front room of our house - which would never have happened with the other boxes. No smell, no tracking, doesn't look like a litter box, easy to maintain.

**PLEASE READ**
This was probably one of the best purchases I have made In. My. Entire. Life. To start, I felt the need to mention that I hardly leave typed reviews-- but this beauty box absolutely warranted one! I have three loving tomcats. Two are well above 13lbs, while the third is way smaller - I'd say about 5lbs. They all use one litter box. Now I know what you're thinking. "Three male cats using ONE litterbox?? INSANITY!!!" No, it's not nearly as bad as you think. But before I bought this, I had a traditional colossal-sized that had the side door. Nothing fancy, just huge. It came with one of those cheap doors, but they would not enter with it on. They just did not like it. I don't know why but every single time they used the box, they would jump out with litter dust too. It would be all over the bathroom floor. It happens so much that the handheld vaccum that I kept in there had to be replaced with an actual vaccum. I have OCD with compulsive cleaning, so I would vaccum multiple times a day. The thought of stepping on any litter bits sends in a spiral. But I'm not even halfway done. Whenever my fiancé would replace the litter, the boys will have a field day. Typical, right? However, my smallest cat...I swesr thst little guy has horse legs! Before he would go, he would kick and splash all inside the darn thing. And he would do it for almost an hour! Constantly digging as if it were some sort of game! You can hear the litter flying OUT of the box and smacking against the bathroom closet wall. Every. Time. And because of this, when they would go number #2, it would smell a billion times worse--because there would be little to zero litter to cover it! BECAUSE ITS ALL AGAINST THE WALL!!! It may sound silly but this was affecting not only me, but my fiance as he constantly had to make trips to get new litter. The crashing sound of fresh litter smacking the bathroom wall in the middle of the night. Me constantly vacuuming. Litter feet. Ugh. This is where our new savior was blessed upon us **WHERE THE ACTUAL REVIEW BEGINS** It is huge. PERFECT. I have three cats and two of them are very big boys. (two 1yr 15lbs each and one 7mo 5lb.) At first they were really skeptical of it's presence. What I had to do was to put a couple treats inside the box, without litter. I also put a couple toys inside, to show that this thing was completely harmless. It took a moment, but two of them were taking turns hopping in and out of it! Bliss! The third still was having trust issues, and refused to enter. So my fiance decided to put it to the true test and actually put litter in it. And to my surprise, they were trying to use it AS he were placing the litter inside! They jump through the hole with ease. The ridges on the lid help a ton with shaving off excess litter off their paws. (We cut their nails every 2 weeks so that'll help too.) And just incase we still have litter catch mats placed underneath. everything had been bliss since this purchase. Now there will be tiny bits of litter here and there on the main bathroom floor, but that's it. Nothing more! I've finally put away my large heavy duty vaccum as there is no need anymore. My little guy still has his litter-kicking-digging-splash fest, and every bit of it is contained. This box prevents splash 100%. And I have noticed that the smell has been covered better! The lock feature is so easy to use - just push the two side buttons in and lift the top. Easy!!!!! This litter box has saved my Mentality !! NO LITTER FEET!!! THANK YOU AMAZON

I hate litter boxes, but this one is pretty great...for a litter box!
So here's the thing. This is a very stylish litter box, which is what we needed for our house. We don't have a lot of space, so her litter box is literally right next to our dining room table. When we see her business in her box or litter scattered on the floor while we're eating, it is just very off-putting. This new box does a pretty good job of keeping those issues hidden from our view. Here are the other positives: -The large size is big enough for our cat to move around in it—in fact, it's the biggest one we were able to find. Most litter boxes marketed as such are not nearly big enough for even small cats to be comfortable! -We were concerned based on some other reviews that she might get poopy paws, but we are so relieved that even when she was sick with diarrhea for a week, that never happened. I think that if your cat knows how to use this particular box correctly, they aren't going to make a big mess like that. She does most of her digging and burying while standing on top and reaching down. It's actually really funny to watch! If your cat were to do all of their digging and burying while they are still inside the box, I could see how that might be an issue, especially if you aren't scooping every day. -The lid definitely keeps grains of litter off the floor. We don't have to vacuum as frequently. -The privacy lid keeps our cat from getting spooked. In a regular style litter box, sometimes if we move the wrong way or close a door while she's doing her business, she'll freak out and leave the box before she's done. Yuck! That very rarely happens when she's using her new box. Now, on to the negatives: -For whatever reason, the cute oval shape of this litter box (or maybe the fact that she has more privacy?) is making our girl do some weird things, like do her business right up on the plastic rather than covering it in her litter. So, while she's having no trouble getting into the box, she's started to get a bit impolite about how she covers it up. We definitely have to clean her box more often to get smelly stuff off the plastic. -The scoop that this box comes with is not really doing it for us. The handle is quite short considering how deep the box is, so I feel like I have to really get in there, which is not my fave. If a new model comes out, I really hope that they will include a longer scoop! Is it all worth it to have a litter box that does not look so much like a litter box? YES!

Loved it so much I bought three (for my 4 cats)
I love these litter boxes so much that I’ve bought three of them! The top-entry design really helps contain the litter instead of having it tracked everywhere, which is a huge plus. They’re durable, super easy to clean, and have held up really well with multiple cats using them. My cats took to them easily and seem to love them too. Definitely one of my favorite cat-owner purchases!

After 7 other litter boxes, this is the VERY BEST & LEAST EXPENSIVE! Even our tripod loves it!
EDIT: We now have three of these for our two cats, and even our tripod cat loves it! We recently adopted a cat who had to have her left back leg amputated before we got her, and I was worried that she would not be able to use this litter box since she has lost half of her "jump" power, so I brought out a lower tray litter box for her. However, she refused to use the tray one and figured out quickly how to use this one, so we got two more of them so they'll always have options. Wish I'd found these long ago--they're the best litter boxes we've ever had. ORIGINAL REVIEW: I've purchased 8 litter boxes in the last year, spending over $500 on them all. I'm so excited to say that I've FINALLY found the very best one! And the fact that it's the least expensive of all the ones I've purchased is the icing on the cake. This litter box is so perfect precisely because of its simplicity. My cat loves to kick his litter everywhere. So, after 5 boxes that had varying degrees of high walls, I realized I needed to get a full enclosure box. This is the third I've gotten. The first two had walls + top you assembled and a pull out bottom tray. DO NOT GET THOSE! The assembled walls have thin open spaces that still allow litter to get out, and the bottom trays only slide out after you have manually brushed the litter inside them flat. Then, I was having to use a large paint brush to remove all the litter he'd kicked up onto the horizontal ledges all over the inside of the walls. And, even after doing that, it made a mess EVERYWHERE when trying to sift the litter clean. This is an extremely straight forward box. No bottom tray (yay!) no crevices for litter to get caught or kicked into = NO MESS AT ALL! I've had to keep honeycomb mats under the previous boxes to trap the litter he got in his paws, but this one has the ridges built into the top to catch it all before he steps off it. Brilliant design, super easy to remove the top, and such a cinch to clean! I let my cat play in it for about 6 hours before filling it up, just to be sure he would like it. He loves it. The hole is also big enough for a large cat---I'd say up to 20 lbs or so. My cat is 10 lbs and there's a huge amount of space for him. And the box itself is also definitely big enough for average Maine Coons, if you were wondering. But its rounded shape means it takes up considerably less floor space than square boxes. A truly innovative design, as litter boxes go.

Great litter box
I got this litter box about a year and a half ago or so for my two cats. I’ve absolutely loved this box since I got it. Since it’s a closed top it has helped us with litter tracking tremendously, we put a litter catcher mat under it for the litter that does get on the floor, but it’s minimal and that issue has pretty much resolved itself, plus most of the litter that does make it out of the box falls off cats paws onto the top of the box with the ridges it has. I was a bit skeptical about how sturdy the box was going to be since reading reviews before I bought it, but it’s been over a year now and we’ve had no problems with it falling apart or breaking in any way, my one boy is almost 17lbs now and still no issues, I believe this box was just made really well or I’m getting lucky. It helps tremendously with the smell too, I’ve noticed that compared to my other open litter box it traps most smells and my home and the bathroom it’s in stays smelling clean, unless you were to get the box rancid but I think a responsible cat owner won’t have that problem! It’s easy to clean, sleek looking, cats can’t kick litter out of it, easily accessible when going to clean, and you don’t have to stare at litter every time you see it! My cats love it, if they haven’t changed the manufacturing of the box 11/10 recommend I wouldn’t get another box unless it was that litter robot or something! Update: still going strong as of 9/21/2025!

No litter scatter!
Ok, I know this is a litter box but I have to say I love this thing. Our cat figured out how to use it right away. It has eliminated litter tracking entirely. She can dig and paw all she wants, but no litter escapes. The lid design is great because the grooves catch any litter that might be tracked out. The best thing is this keeps our dog out of the litter box! She was always nosing around the old one, scattering waste and litter everywhere. This is worry free! The outside of the box is shiny plastic. I thought it was matte from the photo. The blue is also much brighter, almost a royal color. The scoop does hook to the lid which I appreciate, but is pretty flimsy so it pays to have a sturdy one to use. Overall, a great box that has solved what we wanted it to!

Good size and stops mess.
This product works brilliantly. Took cat a couple of try’s to get used to it but it’s big enough for a full grown cat to use. Emptying is a little tricky as it’s large size makes it harder to hold but other than that it’s perfect. Comes with litter tool with hook so it can be placed on side of tray. Now my dogs can’t tip the tray over or attempt to eat it’s contents and the cat doesn’t rip up the carpet by digging around the edges of the tray or bring half the litter out onto the floor. Definitely a tidier type of tray!

Hermoso y mi gatita lo adora
Ya tenía un arenero de esta marca pero en color distinto, esta vez elegí el blanco con beige. En la foto de amazon parece que el color es rosa, pero en realidad es como beige claro. Me encanta el diseño y el tamaño grande considero que es perfecto para mi gatita, es adulta pero no de talla grande, aún así considero que le resulta muy cómodo. Es fácil de limpiar y retiene los olores bien, no diría que por completo pues tiene una gran abertura. El tamaño grande resulta estorboso a la hora de viajar, pero si sólo estará en casa es perfecto. Las ranuras que tiene para eliminar la arena de las patitas del gato una vez que sale, ayuda a reducirlo, pero definitivamente que el gato va a sacar arena, más si sale rápidamente. El material es de buena calidad, los acabados son buenos, los colores bonitos, una vez que lo lavas y con una limpieza diaria no acumula olores, también es resistente, aunque si es sensible a rayones. Algo que no me gustó de este modelo blanco/beige y que me encantó del modelo gris es que la pala traía un metal para colgarla en la parte de atrás y que no se viera. Éste modelo no la trae, pero sí tiene la ranura para ponerlo, por lo que le dejé el que tenía del gris. Sin embargo la pala cambió, ahora el orificio no es una huellita, es un óvalo, que sí entra en el sostenedor de metal, pero a presión, y en mi opinión se veía mejor la patita de gato, además de encajaba perfectamente.

Clean floor, much less smell, cats love it!
I was worried when I purchased this in case my cats didn't like it, because it is not the cheapest choice out there, but I am so pleased I did. I bought at the same time a large rubber mat to put in front as I am used to treading in so much litter brought out of my old litter tray, but this has so little mess outside the litter tray that I almost didn't need it. The amount of litter on my floor now is reduced by 99% with this litter tray and the mat. However, the amount would have been reduced by 90% with this tray alone. The amount of smell that I used to get from my front opening tray is reduced by 70%, which is fantastic. It looks very attractive, and you do not know it is a litter tray. I have people ask what it is. I am so pleased with this purchase and wouldn't change it for the world!
