Frequently Asked Questions
Everything cat parents ask us most, in one place - shipping, materials, litter compatibility, dimensions, and more.
How many Mewvales do I need?
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.
What comes in the box?
Your Mewvale with both the Standard Grill and the Precision Grill. Every box also comes with free gifts: a Litter-catch mat that sits under your Mewvale ($29 value), the Easy-Switch Kit that helps your cat switch in 3 days (3-day plan, attractant sachet, catnip pouch) and a Liner roll that fits the waste drawer.
When will I receive my Mewvale?
Mewvale is in stock. Orders arrive in about 7 days, and shipping is free.
Is Mewvale 3D printed?
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.
Do you ship internationally?
We ship free to the United States and the United Kingdom, arriving in about 7 days.
Will Mewvale rotate while my cat is inside?
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.
Will clumps get stuck at the bottom?
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.
Will my cat fit?
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.
What are the dimensions?
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).
Will you make an XL size?
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.
Can my senior or disabled cat use Mewvale?
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.
What types of litter work with Mewvale?
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.
Does Mewvale work with pine pellet litter?
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.
Does Mewvale work with tofu litter?
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.
How do I clean Mewvale?
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.
Can I use plastic liners in the waste drawer?
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.
Will clumps stick to the sides?
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.
Does Mewvale have a warranty?
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.
What is your return policy?
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.
How is Mewvale different from an automatic litter box?
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.
Who sells Mewvale?
Mewvale is a brand operated by VIS CURA EL LLC, the seller of every Mewvale order. Questions: support@moonlitterbox.store, we reply within 1 to 2 business days.
