Cat Supplements: 2026 Stocking Guide | JustForPetStore

Cat supplements are the smaller, faster-growing half of a $2.9 billion global market. Grand View Research puts pet supplements at $2.9 billion in 2026, with dogs holding 63.1% of revenue, and forecasts the cat segment to grow 7.2% a year through 2033 against 6.9% for the market overall. The constraint is not demand. It is format: most of the category is sold as chews that cats will not eat.

How big is the cat supplement market in 2026?

The Grand View Research pet supplement report sizes the global market at $2.8 billion in 2025, $2.9 billion in 2026 and $4.6 billion by 2033, a 6.9% compound annual rate. North America takes 48.1% of global revenue, Asia Pacific is the fastest-growing region at 8.1%, and Europe grows at 7.0%. Over-the-counter products hold 86.5% of sales, which matters to a retailer because the prescription share is the part you cannot stock.

Dogs account for 63.1% of revenue in 2025, which leaves cats with a little over a third of the category, but the cat segment is forecast to grow faster at 7.2%. Application split is concentrated: hip and joint is the largest use at 21.56% of revenue, while digestive health is the quickest-growing application at 6.3%. Offline retail still holds 76.5% of sales, with online growing at 9.0%.

Why do cat owners buy fewer supplements than dog owners?

Format explains most of the gap. Chewables hold 69.8% of the supplement market, and a chew is a delivery system built around a dog’s willingness to eat almost anything. Powder holds a smaller share but grows at 7.1%, and powder is the format that fits a cat: a scoop stirred into a spoon of wet food disappears, whereas a chew gets sniffed, licked once and left on the floor.

The rest of the gap is basket economics. APPA’s industry data shows U.S. pet food and treats at $68.3 billion in 2025, rising to a projected $69.7 billion in 2026, across roughly 95 million pet-owning households. Food and litter are the fixed costs of cat ownership; supplements are an add-on that a customer only buys when someone explains why. In a dog household the chew aisle does that explaining on its own. In a cat household, the store has to do it.

Which formats actually sell to cat owners?

Four formats earn shelf space. Powder in a tub with a measuring scoop is the workhorse, and it is the format the market data says is growing. Liquid and pump products suit cats that reject dry powder and suit owners who want a visible dose. Small soft chews work for a subset of cats, usually the ones already eating treats, so carry one brand rather than four. Capsules that can be opened over food serve the owner who wants a precise dose without a proprietary blend.

Two practical rules follow. First, carry a trial size of every powder before you carry the full tub, because the risk in this category is a customer buying once and never again after a refusal. Second, check the daily dose on the label and price the product by cost per day, not by tub. A $34 tub that lasts 30 days is easier to sell than a $28 tub that lasts 15, and the customer works that out at home if you do not.

What can you legally claim about a supplement?

In the United States there is no separate regulatory category for pet supplements. A product is regulated as animal food unless it claims to treat, cure, prevent or mitigate disease, in which case it is a drug and needs approval as one. That line is the reason shelf talkers in this category get stores into trouble: a card that says a product “treats arthritis” converts a food product into an unapproved drug claim.

The second trap is the phrase “AAFCO approved.” AAFCO’s consumer guidance explains that the association publishes model regulations for states to adopt and does not approve, test or certify products; enforcement sits with the FDA and state feed regulators. So when a brand’s packaging leans on AAFCO as an endorsement, ask the rep what the label actually carries: a guaranteed analysis, an intended-use statement, a lot code and a best-by date. A brand that answers those four questions quickly is usually the safer stock.

What belongs in a starter assortment?

Aim for 14 to 18 SKUs across five functions, not a wall. Start with joint and mobility, the largest application in the data at 21.56%, in two sizes. Add digestive and probiotic support, the fastest-growing application at 6.3%, plus one omega skin-and-coat product and one calming product, both of which match the trend toward preventive use in aging pets. Then add urinary support, which is the one function that is genuinely cat-only and gives the shelf a reason to exist next to the dog aisle.

Finish with one multivitamin and stop. One brand per function, two sizes per brand, no duplicate formulations from three manufacturers competing for the same four inches. The category rewards clarity: an owner standing in front of six products with six different dosing charts buys nothing, while an owner standing in front of one product with a clear daily scoop buys it and comes back in a month.

Where should the shelf sit in the store?

Put cat supplements with the wet food, not with the dog chews. The purchase is a food add-on, and the customer who is already holding a case of cans is the one who will consider a powder. A small sign with three questions – how old is the cat, does it eat wet or dry, what changed recently – does more work than a poster of a smiling cat.

Keep the shelf low enough to read and lit well enough to read the label, because dosing information is small type. Beside it, place a single dosing card for the brands you carry and a stack of your own reorder reminder cards. If your cat care section already has grooming and cat grooming care products, the supplement shelf sits naturally at the end of that run, where an owner is already thinking about the animal’s body rather than its dinner.

Does online help or hurt a supplement sale?

Both, in sequence. Offline retail holds 76.5% of supplement sales, so the first purchase still happens in a store, usually after a conversation. Online grows at 9.0%, the fastest channel, and it wins the refill because a 30-day supply runs out on a predictable date and the customer is not near your door on that day.

The counter is not to fight the refill but to own it. Sell the first unit with a reminder card, offer pickup on the reorder, and keep the exact SKU in stock so the customer is not forced to substitute. If you carry a brand the marketplace discounts below your cost, sell the function rather than the brand: the customer who understands why the powder matters will pay your price for the version you can explain.

How do you vet a supplement supplier before the first order?

Six questions, asked before the purchase order rather than after. What is the guaranteed analysis, and does the label carry an intended-use statement? Where are the ingredients sourced and are they tested per lot? What is the minimum remaining shelf life on arrival – ask for 18 months and see whether the supplier flinches? What is the MOQ per SKU and per flavor, and can they ship a mixed pallet? What happens to short-dated stock? Will they supply the label artwork so you can check claims before you print a shelf card?

For a private-label program, add two more: whether the manufacturer will run your label at a low minimum order rather than a full production run, and whether they will send a certificate of analysis with each batch. A supplier who cannot answer the shelf-life question is telling you something about how the rest of the relationship will go.

What kills supplement sales in an independent store?

Four things, in order of frequency. Expired stock, because a tub with four months left is a tub nobody wants and the markdown trains customers to wait. Too many SKUs, because a confused owner leaves. Staff who cannot explain dosing, because the category sells on explanation. And claims that cross the line into disease treatment, because the fastest way to lose a good brand is to be the store that made it sound like a medicine.

The fix is unglamorous: order small, rotate on a first-in-first-out rule, review the shelf every quarter for anything under nine months of shelf life, and write a one-page dosing script for the three functions you sell most. Then treat the shelf as a service rather than a display. The stores that sell supplements well are the ones where somebody behind the counter can answer a question in one sentence and then hand the customer the right tub. If you want a starter assortment priced at a low minimum, send us the functions you want to cover and we will build the list against your shelf.

Are cat supplements growing faster than dog supplements? Yes. Dogs hold 63.1% of revenue, but the cat segment is forecast to grow 7.2% a year through 2033 against 6.9% for the market overall.

What supplement format sells best to cats? Powder that can be mixed into wet food. Chewables dominate the overall market at 69.8% because they suit dogs, while powders are growing at 7.1% and fit a cat’s eating behavior.

Can a pet store say a supplement is AAFCO approved? No. AAFCO publishes model regulations that states adopt and does not approve, test or certify products; FDA and state feed regulators enforce. A label claim to treat disease would make the product a drug.

How many supplement SKUs should a small store carry? Start with 14 to 18 SKUs across five functions – joint, digestive, skin and coat, calming and urinary – with one brand per function and two sizes.
