How Plastic Absorbs Smell

Plastic looks smooth, but it isn't.

It's full of pores, little pockets that soak in liquid like a sponge.

Every time your cat goes pee:

Some gets scooped out

Some clumps up

And some seeps down into those pores

You can never wash it out. 

When I cleaned my plastic litter box, I could smell the urine no matter what.

You can't hide it either - Scented products often make the smell worse, like perfume mixed with cat pee.

Does This Happen to All Plastic Boxes?

Yes. Every single one.

Because no matter the shape, brand, or price, all plastic is porous.

If it’s plastic, it will eventually hold onto odor.

There’s no version of it that doesn’t.

And it's not that companies don't know this.

The pet industry makes over $340 million a year selling “odor control” solutions:

Sprays, scented litters, air purifiers, candles, replacement plastic boxes...

They've turned a material flaw into a money machine.

How to Stop Smell From Developing (And save some money)

Before I even knew what caused litterbox smell, I had spent hundreds trying to fight it.

I had expensive scented litter delivered each month, used odor sprays and even bought a $100 air purifier.

Now I know that none of these can actually deal with the smell. 

The truth is, there's no safe way to get the smell out of a plastic box. 

The $60 Solution to the $900 Problem

When I first found the truth about plastic boxes on a vet website, there was only one solution they recommended:

Stainless Steel.

The price was $60 for a steel box. Four times the price of plastic.

I knew I'd spent a lot more than that fighting smell already though - I did the math.

$35/month on litter
$40/month on sprays, candles, and plugins
$100 for an air purifier

Total: $900 this year alone

I was more than happy to spend $60 on something that would actually stop the smell from forming, not try to hide it.

My Experience With Steel

I ordered the box immediately - I was done worrying about smell.

Once it arrived, my boy Milo used it right away. 

I felt bad for making him deal with a plastic box all that time.

I could tell he was much happier with steel.

I let him keep using it for a couple days to see if the smell would develop. 

A few days later, I checked:

Totally clear. No smell.

It felt like a weight lifted off my back.

I called my daughter who'd told me about the smell (thank god) and told her to bring the kids over.

I still remember what she said: 

"Mom, I don't know what you did, but your house doesn't smell anymore."

It really had worked.

Why I'm Sharing This (And Why Stock Won't Last)

I wish someone had told me about stainless steel a year ago.

Would've saved me $900 in useless products.

Stopped dozens of people from smelling my litterbox of a home.

The cat litter industry doesn't want you to know this.

They profit from keeping you on the hamster wheel of replacement boxes and "odor control" products.

But word is spreading.

The company I bought from (Nuava) is a small operation.

They manufacture in limited quantities because medical-grade stainless steel is expensive to produce.

And here's the problem:

For years, veterinary clinics and animal shelters have been using expensive custom-ordered stainless steel boxes made with non-medical grade steel. They worked better than plastic, but weren't ideal.

Now that Nuava is offering true medical-grade boxes at reasonable prices, these facilities have started bulk ordering. They're replacing all their old boxes with proper medical-grade stainless steel.

Stock is not likely to last. And when it runs out, prices will probably go up due to increased material costs and demand.

Right now, the price is $60.

But once shelters and clinics buy up current inventory, I wouldn't be surprised if prices go up due to material costs and demand.

Why I Went With Nuava Specifically

Not all stainless steel litter boxes are the same.

When I started researching, I found a lot of cheap knock-offs flooding the market. Thin steel that dents. Seams where bacteria still hides. Lower-grade metal that rusts.

Companies trying to cash in on the trend without actually solving the problem.

Nuava is different. It's sturdy. Doesn't feel cheap. Here's a few of the reasons why:

Medical-grade 304 stainless steel: The same material hospitals use for surgical equipment. Completely non-porous. 

Welded construction: No joints or crevices for bacteria to hide. Just one smooth surface. 

Built to last forever:  This is the last litter box I'll ever buy.

That's why I went with Nuava. And it's why I can finally have people over without that pit in my stomach.

What Happens When You Order

Step 1: Click the button below to check if they have stock (it goes fast when shelters order in bulk)

Step 2: Order arrives in 5-7 business days

Step 3: Replace your plastic box. Use the same litter, same location, same routine.

Step 4: Within 48-72 hours, all lingering smell is gone.

Nuava is offering a 90-day money-back guarantee. If you don't see a dramatic difference, you can return it for a full refund.

I've told dozens of people about this. Not one has returned theirs.

I wasted 3 years and $900 trying to fix a problem I didn't understand. You don't have to make the same mistake.

The smell can be gone by this weekend. You can finally stop worrying about what people notice when they walk through your door.

What Other Cat Owners Are Saying

"My two cats are older and the plastic boxes would smell even right after washing them. Steel boxes solved it completely. Nothing absorbs into the material so there's no smell anymore. Pretty simple fix."

-Rebecca T, Chicago

"Vet tech here. We use stainless steel at work and I always wondered why consumers use plastic. Finally got a Nuava for home and it's exactly like our clinic boxes, zero smell, lasts forever, actually sanitizable. Stop wasting money on plastic."

-Marla L, Denver

"My boyfriend was dropping hints about the smell. I was so embarrassed. Tried everything. Finally got this after reading about the bacteria-in-plastic thing. Day 3, he commented that it 'smells way better.' We haven't discussed it since. Relationship saved, honestly."

-Francine M, Seattle
