# Cat Litter Mats (2026): Honeycomb, Rubber and Waterproof Layers > Honeycomb, coiled-mesh and silicone cat litter mats compared by size and waterproof layer, with each maker's cleaning steps and how to size a mat to your box. - Source: https://petprooflab.com/potty-cleaning/cat-litter-mats - Publisher: PetProofLab (https://petprooflab.com) - Published: 2026-09-28 - Category: potty-cleaning - Tags: cat litter mat, litter trapping mat, honeycomb litter mat, litter tracking, litter box, waterproof litter mat - Method: picks chosen from Amazon listings and brand specs; not hands-on tested; current Amazon prices are on the page; content checked 2026-09-28. - Quick answer: For most litter boxes, a double-layer honeycomb mat traps the most litter and pours it back: the Pieviev 30 x 24 in or iPrimio 30 x 23 in, both with a waterproof bottom layer. For a single-layer mat that grips the floor, the Gorilla Grip coiled mesh (35 x 23 in) or Amazon Basics (35 x 24 in). For a cat that pees over the edge, the Gorilla Grip silicone mat has a raised edge that holds 16 cups. Choose a mat that reaches past the box entrance. ## Key takeaways - Honeycomb (double-layer) mats let litter fall through the top into a closed bottom layer that you pour out; Pieviev and iPrimio work this way. - Coiled-mesh mats (Gorilla Grip, Amazon Basics) catch litter in the surface and grooves; you shake or vacuum them. - Only the silicone mat gives a liquid figure: Gorilla Grip says its raised edge holds 16 cups. - Size the mat to the box's exit, not the box: a top-entry or front-door box drops litter where the cat steps out. - The ASPCA says to scoop at least once a day; if a cat starts going outside the box, it says to rule out medical problems with a vet first. ## Products (chosen from listings, not tested) 1. **Pieviev Double-Layer Litter Box Mat, 30 x 24 in** (details: https://petprooflab.com/potty-cleaning/cat-litter-mats#product-B01MTQNK6H) — The double-layer mat to start with for a standard box. - Pros: Honeycomb top layer over a waterproof, slip-resistant bottom layer, per Pieviev; Soft EVA foam; open one edge and pour trapped litter back into the box; Hose off or wash; also sold in 24 x 15 and 36 x 30 in; sold by Pieviev - Cons: Pieviev gives no figure for how much liquid the bottom layer holds 2. **iPrimio Cat Litter Trapper Mat, 30 x 23 in** (details: https://petprooflab.com/potty-cleaning/cat-litter-mats#product-B0163NXEM8) — A light honeycomb mat that is easy to take to the tub, from a maker candid about its edge. - Pros: Double layer with large holes and a plastic film that iPrimio says repels urine; EZ Open Edge to shake out or rinse under a sink or shower head; Very light; sold by iPrimio USA - Cons: iPrimio says the nylon mesh border can absorb urine and suggests puppy pads for very messy cats; limited stock when we checked 3. **Gorilla Grip Coiled Mesh Litter Mat, 35 x 23 in** (details: https://petprooflab.com/potty-cleaning/cat-litter-mats#product-B01MDNDDYS) — A floor-gripping mesh mat for an active cat that kicks a mat out of place. - Pros: Thick mesh coils and deep grooves on top catch litter; textured backing to stop it shifting, per Gorilla Grip; Water-resistant material designed not to let liquid through; Tip litter back into the box, vacuum or shake; wash with mild soap and water; sold by Gorilla Commerce, Gorilla Grip's maker - Cons: A single-layer surface: litter sits in the coils rather than in a closed pocket 4. **Gorilla Grip Silicone Litter Mat, 30 x 24 in** (details: https://petprooflab.com/potty-cleaning/cat-litter-mats#product-B0G1CX5DX3) — The mat to put under a box when spills and overshoots worry you more than tracking. - Pros: 100% silicone with a 0.2 in raised edge that holds 16 cups of liquid, per Gorilla Grip; Third-party tested as waterproof and stain resistant, the maker says; BPA free; Wipes clean; folds to pour litter back; hanging hole for drying; sold by Gorilla Commerce - Cons: A smooth surface catches less litter off the paws than a honeycomb or mesh top 5. **Amazon Basics Litter Trapping Mat, 24 x 35 in** (details: https://petprooflab.com/potty-cleaning/cat-litter-mats#product-B072569V1L) — A large, plain mesh mat for the floor in front of a big box. - Pros: PVC mesh-coil surface with crisscross grooves and a deep border along the edge, per the listing; Waterproof backing; soft to step on; One-year limited warranty; sold by Amazon.com - Cons: The listing gives no cleaning instructions 6. **Catit Litter Mat, 15.75 x 23.5 in** (details: https://petprooflab.com/potty-cleaning/cat-litter-mats#product-B07KSNNGNP) — For a tight spot, such as a box in a closet or bathroom corner. - Pros: Textured surface for clumping, crystal and lightweight litters, per Catit; Non-slip backing; shake, vacuum, or wash with mild detergent and warm water; Dries quickly; sold by Amazon.com - Cons: The smallest mat here; too short for most box exits To stop litter tracking out of the box, put a mat where your cat steps out: a double-layer honeycomb mat such as the Pieviev or iPrimio traps the most and pours back into the box, and a coiled-mesh mat from Gorilla Grip or Amazon Basics grips the floor better. If urine over the edge is the bigger problem, the Gorilla Grip silicone mat has a raised rim that holds liquid. This guide compares six mats by size, surface and waterproof layer, and sets out each maker's cleaning steps. **How we chose:** we did not test these mats; sizes, materials and cleaning steps come from each maker's listing, and every pick was sold by Amazon.com or the brand's own store and in stock on September 28, 2026. ## Six litter mats side by side | Mat | Surface | Size | Waterproof layer, per maker | Sold by | Amazon price | |---|---|---|---|---|---| | [Pieviev Double-Layer](https://petprooflab.com/potty-cleaning/cat-litter-mats#product-B01MTQNK6H) | Honeycomb, 2 layers | 30 x 24 in | Waterproof bottom layer | Pieviev | see the current Amazon price on the page | | [iPrimio Litter Trapper](https://petprooflab.com/potty-cleaning/cat-litter-mats#product-B0163NXEM8) | Honeycomb, 2 layers | 30 x 23 in | Urine-repelling film | iPrimio USA | see the current Amazon price on the page | | [Gorilla Grip Coiled Mesh](https://petprooflab.com/potty-cleaning/cat-litter-mats#product-B01MDNDDYS) | Mesh coils, grooves | 35 x 23 in | Water resistant | Gorilla Commerce | see the current Amazon price on the page | | [Gorilla Grip Silicone](https://petprooflab.com/potty-cleaning/cat-litter-mats#product-B0G1CX5DX3) | Smooth, raised edge | 30 x 24 in | Holds 16 cups | Gorilla Commerce | see the current Amazon price on the page | | [Amazon Basics](https://petprooflab.com/potty-cleaning/cat-litter-mats#product-B072569V1L) | Mesh coils, grooves | 24 x 35 in | Waterproof backing | Amazon.com | see the current Amazon price on the page | | [Catit](https://petprooflab.com/potty-cleaning/cat-litter-mats#product-B07KSNNGNP) | Textured | 15.75 x 23.5 in | Not stated | Amazon.com | see the current Amazon price on the page | Pieviev, Gorilla Grip and iPrimio sell other sizes, including a 36 x 30 in Pieviev and a 24 x 15 in Gorilla Grip honeycomb for small boxes. ## Honeycomb, coiled mesh or silicone? **Honeycomb, double-layer mats** (Pieviev, iPrimio) have a top layer full of large holes over a closed bottom layer. Litter stuck to the paws falls through the holes and stays in the pocket between the layers. To empty it, you open one edge and pour the litter out. Pieviev describes it this way: "You just pick up the mat and all the litter falls through and then dump it back in the litter box." Gorilla Grip makes a honeycomb mat too, in a small 24 x 15 in size. **Coiled-mesh mats** (Gorilla Grip Coiled Mesh, Amazon Basics) are single sheets with a loopy vinyl surface and grooves. Gorilla Grip says the "thick mesh coils" grab litter and the "deep grooves on the topside also collect litter," with a textured backing that keeps the mat in place "even with active cats." Litter stays in the surface, so you shake, tip or vacuum it off. **Silicone mats** (Gorilla Grip Silicone) are smooth, with a raised edge. They catch less litter from the paws but hold spills: Gorilla Grip says its 0.2 in edge "holds 16 cups of liquid" and that the mat is third-party tested as waterproof. A **textured rubber-backed mat** like the Catit is the simplest: a soft surface that brushes litter off the paws and a non-slip back. ## How big a mat do you need? Size the mat to where your cat leaves the box, not to the box itself. A cat steps out and shakes its paws in the first stride or two, so the mat needs to reach past the entrance. - **Open box:** the cat can step out on any side. Use a mat at least as long as the box's longest side, or put the box on the mat. - **Front-door or hooded box:** litter comes out in one place. A mat that starts at the door and runs a couple of feet out does more than a wide one. - **Top-entry box:** the cat climbs out of the lid, so litter lands where it jumps down. Put the mat there. As a rough guide, the 30 x 24 in mats (Pieviev, Gorilla Grip Silicone) and 35 in mats (Gorilla Grip Coiled Mesh, Amazon Basics) suit a standard or large box. Measure your box's footprint and its exit before you buy; our [litter box guide](https://petprooflab.com/potty-cleaning/best-cat-litter-boxes) gives the dimensions of each box it covers. The ASPCA's [litter box problems page](https://www.aspca.org/pet-care/cat-care/common-cat-behavior-issues/litter-box-problems) says "the majority of cats prefer large boxes that they can enter easily" and that most cats like "one to two inches of litter rather than three to four inches." If you move up to a larger box, move up a mat size too. ## Waterproof layers and urine A mat that sits in front of a litter box will sooner or later catch urine, whether from a cat that stands too close to the edge or a kitten still learning. What matters is whether it stops there. - **Pieviev** says its bottom layer "is waterproof and also slip-resistant which will not allow any liquid to go through." - **iPrimio** says its film "repels urine," but adds that the nylon mesh border around the perimeter "may absorb urine if excessive," and suggests "puppy pads as they soak excessive urine" for very messy cats. - **Gorilla Grip Coiled Mesh** is "water resistant," designed "to not allow liquids to pass through." - **Gorilla Grip Silicone** holds 16 cups behind its raised edge. - **Amazon Basics** has a "waterproof backing." If urine soaks through to the floor anyway, clean it with an enzyme cleaner; our [enzyme cleaner guide](https://petprooflab.com/potty-cleaning/enzyme-cleaners-pet-stains-odors) explains why. And if your cat has started urinating outside the box, the ASPCA says: "The first step in resolving elimination outside the litter box is to rule out urine marking and medical problems. Have your cat checked thoroughly by a veterinarian." A mat catches the mess; it does not solve why the cat is missing the box. Ask your vet ([more on that](https://petprooflab.com/about#veterinary)). ## Cleaning, by each maker's instructions - **Pieviev:** open the edge and pour trapped litter back; the EVA surface "can be removed easily," and if a cat vomits on it, "you can hose it off." - **iPrimio:** open the "EZ Open Edge" and clean "under sink head, shower head, or shake off." - **Gorilla Grip Coiled Mesh:** "tip and pour collected litter back into the box," vacuum or shake it out, and "for a deep clean use mild soap and water, always air dry." - **Gorilla Grip Honeycomb:** rinse "with soap and water, dry completely," and wash before first use. It may ship rolled or folded; Gorilla Grip says to lay it flat under a weight for at least 24 hours if it is creased. - **Gorilla Grip Silicone:** shake out, wipe clean, and "for deep cleaning use mild soap and water," then hang it from its hole to dry. - **Catit:** "shake off loose litter, vacuum for quick cleanups, or wash with mild detergent and warm water." Several makers suggest pouring the trapped litter back into the box to use less. That's reasonable for dry, clean litter; we would throw away anything that got wet or soiled. For the box itself, the ASPCA says to "scoop at least once a day" and, once a week, to "clean all litter boxes with warm water and unscented soap." Doing the mat at the same time keeps it simple. ## Which one to buy - **Most cats and boxes:** Pieviev Double-Layer, 30 x 24 in. - **You want to rinse the mat in the tub:** iPrimio Litter Trapper. - **An active cat that shoves a mat around:** Gorilla Grip Coiled Mesh. - **Urine or overshoots over the box edge:** Gorilla Grip Silicone. - **A big box and a plain, no-frills mat:** Amazon Basics, 24 x 35 in. - **A closet or bathroom corner:** Catit. The litter itself is the other half of tracking. Our [cat litter guide](https://petprooflab.com/potty-cleaning/best-cat-litter) compares clay, silica, pine and other plant litters. We found no FDA or CPSC recall for any brand on this page in the [CPSC recall database](https://www.cpsc.gov/Recalls) or on our [pet product recall page](https://petprooflab.com/recalls). We looked for an Easyology mat but did not find one sold by Amazon.com or an Easyology store on Amazon. Several large mats from Anywish, USHARP and Kozvva were sold by storefronts whose names did not match the brand, so we left them out. ## Frequently Asked Questions ### Do cat litter mats actually stop litter tracking? They catch much of what comes off the paws in the first steps out of the box. Double-layer honeycomb mats hold litter in a closed pocket; mesh mats hold it in the surface until you shake or vacuum them. ### Are litter mats waterproof? Most say so. Pieviev and Amazon Basics list a waterproof bottom layer or backing, and Gorilla Grip's silicone mat holds 16 cups. iPrimio says its mesh border can absorb urine if there is a lot of it. ### What size litter mat should I get? One that reaches past the box's exit. For a standard box, a mat of about 30 x 24 in or 35 x 23 in covers the first strides out; for a top-entry box, put the mat where the cat jumps down. ### How do I clean a honeycomb litter mat? Open the edge and pour out the trapped litter, then rinse the mat. iPrimio says to rinse under a sink or shower head; Pieviev says you can hose it off. --- *PetProofLab is a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to Amazon.com.
