Best Waterproof Cat Litter Mats

We may earn a commission from links on this page. How this works

Every cat misses the box sometimes. Kittens are still learning, senior cats may have trouble getting into position, and some cats simply stand too close to the edge. When that happens, a regular fabric or foam mat soaks up the urine and passes it straight to your floor. The best waterproof cat litter mats stop liquid at the surface, so you can wipe it up before it damages wood, carpet or tile grout.

This guide covers the waterproof mats that also trap litter well, explains the difference between "waterproof" and "water-resistant" mats, and shows you how to set up a leak-proof litter station.

Waterproof vs Water-Resistant Litter Mats

These terms are often mixed up in product listings, so read carefully:

• Waterproof mats have a solid layer, usually EVA, rubber or a plastic film, that liquid cannot pass through. Urine stays on or inside the mat.

• Water-resistant mats slow liquid down but may let it through if it sits for a while. Many fabric mats with a backing fall into this group.

• Not waterproof mats, such as most foam, sisal and plain rubber-nub mats, let urine pass through or soak in.

If your cat has regular accidents, choose a truly waterproof mat with a solid bottom layer.

The Best Waterproof Cat Litter Mats Reviewed

1. Pieviev Double-Layer Cat Litter Mat — Best Overall Waterproof Mat

Pieviev's design gives you two kinds of protection in one mat. The honeycomb top traps litter, and the sealed EVA bottom layer stops urine from reaching the floor. Because liquid stays inside the mat, you can open it, pour it out and rinse it under the tap. It is a strong all-round choice for homes with kittens or senior cats.

Pros: Waterproof; excellent trapping; easy to rinse.
Cons: Emptying takes practice; may slide on smooth floors.

2. iPrimio Cat Litter Trapper EZ Clean — Best for Extra Protection

iPrimio has a waterproof bottom layer and an open design that leaves room between the layers. Many owners slip a puppy pad in there to absorb urine, which makes cleanup even easier: just replace the pad.

Pros: Waterproof; space for an absorbent pad; jumbo size.
Cons: Higher price; can slide without a grip pad.

How to Build a Leak-Proof Litter Station

1. Use a waterproof tray under the box. A large plastic tray or boot tray catches leaks from the box itself.

2. Put a waterproof litter mat at the exit. This catches tracked litter and accidents just outside the box.

3. Choose a high-sided or hooded box. High walls stop cats from peeing over the edge.

4. Keep the box very clean. Cats often go next to a dirty box. Scoop at least once a day.

5. Use an enzyme cleaner. It breaks down urine odor so your cat does not return to the same spot.

If accidents start suddenly, it is a good idea to talk to your vet, as a change in litter habits can have a medical cause.

How to Clean a Waterproof Litter Mat

• Double-layer EVA: open the mat, pour out litter, rinse both layers with warm water and mild soap, and air-dry.

• Rubber: wipe or rinse, then dry with a towel.

• Coil mats: shake out litter, then hose or rinse in the tub.

• Avoid bleach and ammonia cleaners. Ammonia smells like urine to cats and can encourage them to go there again.

If your waterproof mat will sit on wood, see our guide to the best litter mats for hardwood floors for grip and finish tips.

Signs You Need a Waterproof Mat

• You find damp spots or yellow stains in front of or beside the box.

• Your floor smells of urine even after cleaning.

• You have a kitten that is still learning, or a senior cat who struggles to get into position.

• Your cat stands with their back end hanging over the edge of the box.

• You use a low-sided or open box.

If any of these sound familiar, a waterproof mat is cheaper than replacing flooring or carpet.

Quick Buying Checklist

Before you add a mat to your cart, run through these questions:

1. Does the listing say waterproof, not just water-resistant?

2. Is the waterproof layer solid across the whole mat, including edges?

3. Can it be fully opened or rinsed after an accident?

4. Is it large enough that urine cannot run off the edge?

5. Does it also trap litter well, so you only need one mat?

If a mat answers yes to all of them for your home, it is a good match.

How We Chose These Mats

We compared manufacturer specifications (size, material, layers and waterproofing) with published buying guides and owner feedback, then ranked each mat against the needs of this specific situation: a truly waterproof layer, trapping ability and how easy the mat is to rinse. We did not include mats with frequent complaints about leaking, cracking or holding odor after washing. Prices and sizes change often, so always confirm the current listing before you buy.

Frequently Asked Questions

Are cat litter mats waterproof?

Not all of them. Double-layer EVA mats and solid rubber mats are usually waterproof. Most foam, sisal and fabric mats are not, so check the listing before you buy.

What is the best waterproof litter mat for cats that pee outside the box?

A double-layer EVA mat such as Pieviev or iPrimio is best because the sealed bottom layer holds urine inside the mat until you rinse it.

Can I put a pee pad under a litter mat?

Yes. A pee pad under or inside a litter mat adds absorbency. iPrimio's open design has room for a pad between its layers.

How do I get urine smell out of a litter mat?

Rinse the mat, then use an enzyme cleaner made for pet urine. Let it dry fully in fresh air. Avoid ammonia-based cleaners.

Is a waterproof litter mat good for kittens?

Yes. Kittens often have accidents while learning, and a waterproof mat makes cleanup easy and protects your floors.

Final Verdict

The Pieviev Double-Layer Cat Litter Mat is the best waterproof cat litter mat for most homes because it traps litter and holds liquid in one easy-to-rinse design. For extra absorbency, try the iPrimio EZ Clean with a pad inside, and for full-area protection, the Gorilla Grip in a large size. Compare all our top picks in the best cat litter mats guide.
