If you’ve ever shopped for pet potty pads, chances are you’ve walked down the pet supply aisle squinting at rows of options, wondering if that “light, fresh scent” listed on the packaging is actually a selling point or a marketing gimmick. As a supplier of pet potty pads, I get this question all the time—from first-time puppy parents panicking about potty training to multi-pet households looking for pads that don’t leave their home smelling like a litter box or a stray bathroom. The short answer is: yes, pet potty pads can have a smell—but that smell doesn’t have to be bad, and it’s usually tied to how the pads are made, not some inherent flaw in the product. Let me break down what that smell is, why it happens, and how we craft our pads to keep that scent mild, harmless, and functional for both pets and their people. Pet Potty Pads
First, let’s start with the basics. What actually makes a pet potty pad smell in the first place? Most pads are made of three core layers, and each can contribute to a scent, depending on the materials and manufacturing process. The top layer is usually a soft, non-woven fabric that sits against your pet’s paws—this is the part that wicks moisture away quickly, so your dog or cat doesn’t step in a puddle. The middle layer is the absorbent core, which is where all the liquid gets trapped. This is often a mix of wood pulp and super absorbent polymers (SAP), the same material used in disposable diapers that can hold up to 300 times their weight in liquid. The bottom layer is a leak-proof polyethylene film, designed to stop accidents from seeping onto floors or carpets.
Now, none of these materials are inherently smelly—when they’re fresh and unused, they’re nearly odorless. But two things can trigger a noticeable scent: manufacturing residues and, of course, what the pad is designed to do: absorb pet waste. Let’s tackle the manufacturing side first, because that’s a factor most consumers never see, but it’s one we prioritize heavily at our facility.
When we process non-woven fabric for the top layer, we use a small amount of surfactants to help it wick liquid faster, and a touch of binding agents to keep the fabric from fraying. At our ISO-certified plant, we use only FDA-approved, non-toxic surfactants that are free of harsh chemicals like phthalates, but it’s not unusual for a faint, mild plastic or paper-like scent to linger for a day or two right out of the packaging. That’s not a sign of a bad product—it’s just the residue from the manufacturing process, and it fades completely once the pad is exposed to air for a few hours.
The absorbent core is where the most common “new pad” scent comes from. The wood pulp we use is sustainably sourced from FSC-certified forests, so it goes through a bleaching process to remove lignin, the natural compound in wood that gives it a brown color and a sharp, woody smell. We use elemental chlorine-free (ECF) bleaching, which is safer for the environment and leaves far less residual chemical scent than traditional bleaching methods. Some cheaper suppliers use less expensive, non-ECF pulp, or cut corners on drying the core before packaging, leaving a stronger, more lasting chemical smell. That’s why I always advise customers that if a pad reeks of chemicals the second you open the bag, it’s not a sign of a strong odor-control system—it’s a sign of poor manufacturing practices.
Then there’s odor control, the part that’s supposed to neutralize bad smells, not add new ones. A lot of pet potty pads on the market today use two types of odor control: masking and neutralizing. Masking uses artificial fragrances to cover up the smell of urine and feces, which is where a lot of that artificial “fresh linen” or “citrus” scent comes from. The problem with masking is that it just hides the odor temporarily—once the fragrance fades, the pet waste smell comes back, and many pets can be sensitive to artificial scents, which can cause sneezing, skin irritation, or even deter them from using the pad at all.
At our company, we don’t use masking fragrances. Instead, we use activated carbon and zeolite, natural mineral-based odor neutralizers that bind to the molecules that cause bad smells, breaking them down instead of covering them up. We also add a small amount of probiotics to the core of our premium pads, which eat away at odor-causing bacteria as soon as waste is absorbed. This means the pad doesn’t smell strong when it’s new, and it doesn’t develop a sharp odor as it’s used—until it’s full, and then you just need to replace it. That’s a key difference we focus on: we want the pad to work for your pet and for your home, not to be a perfume bottle with three layers of material.
Now, let’s talk about the other side of the smell question: what happens when a pad is in use, and is that smell normal? Any pad designed to absorb pet waste will develop a scent over time—there’s no way around that, because the purpose of the pad is to hold that waste. But the quality of the pad determines how strong that scent is, and how long it lasts before you need to replace it. A pad with a thicker core will hold more waste, so you won’t have to change it as often, which means less overall scent in your home. A pad with a leak-proof bottom layer will also prevent urine from seeping through to the floor, where it can soak into carpets and leave a lasting, hard-to-remove smell.
I’ve heard from so many customers who switched to our pads after dealing with headaches from cheap pads that started smelling within hours of use. One customer from Chicago told me she was using a budget brand for her senior Yorkie that would leave her living room smelling like a kennel by midday, even though she was changing the pad twice a day. When she made the switch to our premium pads, she said she didn’t notice any odor at all until the 12-hour mark, when her Yorkie would use the pad twice—at that point, it had a mild, earthy smell, not a sharp ammonia smell from old urine. That’s the difference good materials make: the activated carbon and zeolite in our pads neutralize the ammonia that forms when urine breaks down, so the smell stays mild until the pad is ready to be changed.
Another common question we get: do the pads smell bad for cats too? A lot of cat owners are hesitant to use potty pads because they think the scent will deter their cat from using the pad, or that the chemicals in the pad will bother their sensitive noses. Cats have a much stronger sense of smell than humans—their olfactory system is about 14 times more powerful than ours—so the last thing we want is to add harsh scents or chemicals that would make a cat avoid the pad. That’s why all our pads are fragrance-free and hypoallergenic, with no artificial dyes or harsh chemicals. We’ve had so many cat owners tell us that their cats took to our pads immediately, whereas they refused to use other pads that had even a faint artificial scent. The key here is that we prioritize the pet’s needs just as much as the owner’s—if a pad is too smelly for a pet, it’s not a good pad, no matter how well it works for the owner.
Now, let’s address some common myths I hear all the time. One myth is that any pad with a smell is low quality. That’s not true—like I said, new pads might have a very mild, fleeting scent from manufacturing, and that’s normal. Another myth is that unscented pads don’t work as well as scented ones. We’ve done independent testing at our facility where we compared odor control between our unscented premium pads, scented masking pads, and generic budget pads. Our unscented pads had 70% less odor than the scented masking pads after 8 hours of use, because the masking fragrances only cover the smell for a short time, while our neutralizers break it down completely. The budget pads had the strongest odor, because they used almost no odor control at all.
As a supplier, I also want to talk about the environmental side of this, because that’s a big concern for a lot of customers now. A lot of people assume that pet potty pads are all single-use and bad for the planet, which is true for budget pads made of mixed materials that can’t be recycled. But our pads are designed to be as eco-friendly as possible, while still being highly functional. The top layer is made of 100% recycled non-woven fabric, the absorbent core is 60% sustainably sourced wood pulp, and the bottom film is made of 25% recycled polyethylene. We also offer compostable pet potty pads for customers who want an even greener option, made from plant-based materials that break down in industrial compost facilities. We’ve found that many customers are willing to pay a little more for a pad that doesn’t smell bad, works well, and is better for the planet, and that’s the market we’ve built our business around.
I also want to be transparent about when you might notice a smell that’s not normal. If your pad starts developing a strong, unpleasant smell within a few hours of use, that’s not the pad’s fault—it’s probably because you’re not using enough pads, or you’re not replacing them often enough. For example, if you have a large dog, or multiple pets using the same pad, you might need to change it every 4-6 hours, not every 12. Another common mistake is not placing the pad on a waterproof surface—if you put a pad on a carpet without a liner, even the best leak-proof pad can develop a smell as seepage gets trapped between the pad and the carpet. We always include a free small waterproof liner with every bulk order, to help customers avoid that issue.
At the end of the day, pet potty pads should be a solution, not a source of stress. There’s no such thing as a pad that has zero smell, because it’s designed to hold pet waste—that’s part of its purpose. But a good pad will have a very mild scent if it’s new, and will neutralize odors as they happen, so your home stays fresh, and your pet stays comfortable. If you’re tired of pads that smell too strong, don’t work for your pets, or leave you with a mess to clean up, I’d love to connect with you to talk about our products. We work with pet stores, boarding facilities, and individual customers to find the right pads for their needs, and we’re always happy to answer any questions about our manufacturing process, materials, or odor control technology.
