Mewvale

A good rule of thumb is 1 Mewvale per cat for maximum convenience, but one Mewvale can absolutely be shared. 1 cat: 1 Mewvale, clean about 1x/day. 2 cats: 1 Mewvale, clean about 2x/day; 2 Mewvales, about 1x/day. 3 cats: 1 Mewvale, about 3x/day; 2 Mewvales, about 1-2x/day; 3 Mewvales, about 1x/day. The more cats sharing one Mewvale, the more often you'll want to rotate and empty it. For two cats, the Stainless 2-Pack is $7.16.

Your Mewvale with both the Standard Grill and the Precision Grill. Right now, every box also comes with free launch gifts: a Litter-catch mat that sits under your Mewvale ($29 value), the Easy-Switch Kit (3-day switch plan card, litter-attractant sachet, catnip pouch) and a Liner roll that fits the waste drawer.

Mewvale is in stock. Orders arrive in about 7 days, and shipping is free.

No. Mewvale is made from injection-molded ABS with a clean, seamless finish. The Stainless version also has 304 stainless steel surfaces in the major litter and waste-contact areas.

We ship free to the United States and the United Kingdom. Orders arrive in about 7 days.

No. Mewvale locks into place in the neutral position, so your cat won't accidentally rotate it during normal use. We've tested the design with multiple cats without any issues.

Rarely. At the recommended 4 inch litter level, the curved barrel causes litter to naturally fall back toward the center as your cat digs. If a clump does stick, a quick tap will usually knock it loose. Mewvale also includes a hidden emergency scraper for the rare stubborn clump.

Mewvale has a 14 x 14 inch (36 x 36 cm) usable litter bed. Since every cat has different preferences, we recommend comparing this measurement with the usable litter area in your cat's current litter box.

Overall: 22 in L x 16.5 in W x 28 in H (56 x 42 x 71 cm). Usable Litter Bed: 14 x 14 in (36 x 36 cm). Recommended Operating Space: 32 in L x 22 in W (81 x 56 cm).

Right now, we're focused on our standard size, which is designed to fit the vast majority of cats. An XL Mewvale for larger breeds like Maine Coons is definitely something we'd love to explore in the future.

Most cats should be able to use Mewvale comfortably. Cats are natural climbers, and if your cat can handle a normal stair step, they should be able to get in and out without a problem. For super-senior cats or cats with limited mobility, a detachable Senior Ramp is available as an add-on for $29.

Mewvale works with most standard clumping litters. Every Mewvale includes both the Standard Grill and Precision Grill. Recommended: Clay, Corn, Wood, Olive, Wheat, Soft Wood, Walnut, Cassava, Crystal, Silica, Cornstarch, Tofu (Granular) - the best Mewvale experience with excellent sifting and performance. Usable with trade-offs: Standard Tofu, Plant Pellet, Standard Pea Husk - works, but may affect sifting speed, cleanliness, or overall experience. Not compatible: Pine Pellet, Large Paper Pellets. Pine pellet litter breaks down into sawdust and needs a different sifting method - we're developing a version engineered for pine pellet systems.

Not this version. Pine pellets break down into sawdust and require a different separation system. A future version designed specifically for pellet litter is something we'd love to explore.

Yes, but the type of tofu litter matters. Traditional larger tofu pellets are usable, but they aren't the best Mewvale experience. Granular tofu litter works much better and has performed really well in our testing.

Mewvale is fully washable. You can hose it down or rinse it in a bathtub. For a deeper clean, Mewvale can be disassembled to give you access to the interior surfaces and removable separation grill. And because there are no electrical components, there's nothing electronic to protect from water.

Yes. The waste drawer has a built-in lip designed to hold most plastic grocery bags and commercially available small waste liners. Mewvale does not require proprietary bags.

For cats that regularly pee against the walls, yes, this can occasionally happen. A few taps from the outside will usually release the clump and allow it to slide down. For stubborn clumps, Mewvale includes a hidden emergency scraper inside the landing pad storage.

Yes. Lifetime warranty: for as long as you own your Mewvale, we replace any part with a manufacturing defect. If your Mewvale arrives damaged, we'll provide the replacement, parts, or support you need.

Try Mewvale for 90 days. If your cat doesn't take to it, tell us and we'll refund you in full, and you keep the box. Lifetime warranty: for as long as you own your Mewvale, we replace any part with a manufacturing defect.

We see Mewvale as a different approach, not a cheaper automatic litter box. Some cat parents want full automation. Others want something simple, fully washable, and free of motors, sensors, apps, and complicated electronics. That's who we built Mewvale for.
