Top entry reduces litter tracking. Ramp for senior disabled cats. Easy access litter box. Easy scooping. Maine coon sized litter box


In 2019 we launched Boxscoop 2.0 for cats up to ~13 lbs, and we are thrilled to now be launching Boxscoop Curve for cats up to ~20 lbs!

Boxscoop Curve is available in two cover options, our top entry version, or our open top + ramp version.


The first XL easy cleaning litter box

Our scoop is extra large and the stainless steel sifter is engineered to sift fast while maintaining close 4.5MM spacing to pull out even the smallest waste. That means happier cats and fresher litter that lasts longer.

Cats love circular litter boxes

Rectangular litter boxes are as restrictive as their narrowest measurement.

Boxscoop Curve is circular and fully maximizes the litter surface. Cats under 13-14 lbs love Boxscoop 2.0 and Curve now offers that same experience to large, senior and less agile cats.

I poop here... you poop there

Cats are clever... and with our unique patent pending design, they quickly learn to deposit their waste in zones around the litter channel so they know where it is, and avoid stepping on it.

    This is huge benefit for large cats and multi-cat households— they'll quickly learn who does what, where.

    Boxscoop curve with step

    I ordered the boxscoop curve from you last week. Got it Monday, set it up today, Tuesday, and the cat walked up the steps, turned around twice and immediately used the box…flicked some litter and came out…boy this Mom was excited! I wish I had a photo….I did clean her old box and had it ready…but I don’t think I’ll leave it out! I am using the same Boxiecat clay litter because I love the no dust…and it’s pretty fine…I ran the scoop right after I put the litter in. I can hardly wait to scoop it, but since it was pee I will let it there so she has the smell….I praised the heck out of her, and am still smiling! My cat is just two years old and I adopted her 3 months ago. She loves the box it came in also! Thank you for a great product!

    I would love to share that our senior cat ( who was struggling with keeping his urine in the oversized box) has totally accepted your product. No over spill, we’re just absolutely thrilled with the results.

    Absolutely LOVE these litter boxes

    I initially bought one box then added a second and third. This is all that I use for my 4 cats. I use the Sustainably Yours corn litter and scoop once or twice a day. While there is still some tracking of litter I have washable pee pads (that I already had for a senior dog) under the boxes, put litter mats underneath the step and then a boot mat next to the litter mats so the litter stays in one area. I pick up the boot mat every day and dump what has tracked out back into the boxes as well as what lays on the steps. Scooping and cleaning them are a breeze. Very sturdy scoopers that hang on the side of the boxes. My cats love them and I have no issues with odor unless the litter is getting low. Strongly recommend these boxes! Happy to support a small business as well.

    The very best litter box on the market!!

    I have 5 cats. One of them, a large female, couldn’t use a litter box without peeing outside the box, she is that large. I used all sorts of boxes , I even bought one of those plastic boxes that you store wrapping paper in , thinking it would be long enough for her to go a few steps in and pee. But her way is she steps in and squats and again the urine went out of the box. I was at the point of thinking of making her an outside cat as I will not have my house smell of cat urine! I found the box scope on the internet, I bought an ex-large with the step to get up to it. It worked perfectly!!!! The sides are high, they are easy to clean. I’ve now bought two of them! All my old litter boxes I’ve donated to the local shelter and I will never use another box design! I have two for 5 cats, I use the walnut shell litter and clean it twice a day. Perfect!!

    Great litter box and fantastic customer service

    I ordered the XL for my two cats because I was tired of trying to scoop litter out of the corners. I love it and so do my cats so I'm ordering a second XL. The ramp on my first box got cracked, probably from my 18 pound cat, so they are sending a replacement ramp for free.
