Dog and Cat Food Manufacturing (U.S.) — NAICS 311111

An investor's primer. NAICS (North American Industry Classification System) code 311111 covers U.S. factories that make food and treats for dogs and cats — dry kibble, canned/pouched wet food, semi-moist food, and biscuits — from ingredients bought in or processed on site.

1. Overview

This is the factory floor behind a category most people know only from the pet-store aisle: the plants that extrude kibble, cook and can wet food, and bake biscuits for America's dogs and cats. About 95 million U.S. households owned at least one pet in 2025; dog ownership reached 71 million households (53%) and cat ownership 53 million households (39%).[1] It is one of the most defensive corners of consumer manufacturing — pets eat every day, in good times and bad — layered on top of a long-running "humanization" trend that has pushed owners to trade up to premium, natural, and fresh foods.

Why an investor cares: demand is recurring and largely non-discretionary, brands are sticky (owners are reluctant to switch a pet's diet), and the category has grown faster than most packaged-food segments for two decades. The trade-off is that the branded end is dominated by a handful of giants, input costs (meat, grain, packaging) swing margins, and U.S. volume growth has matured after the pandemic pet boom. APPA found that 22% of owners reduced pet spending during 2025, while roughly half reported unchanged spending — evidence of defensive demand alongside real price sensitivity.[1]

Public vs. private ways in. There is no large pure-play "dog and cat food" stock that captures the whole industry. Instead, most public exposure comes inside diversified consumer companies — Colgate-Palmolive (Hill's), General Mills (Blue Buffalo), J.M. Smucker (Meow Mix, Milk-Bone), Post Holdings, and Switzerland's Nestlé (Purina). The one sizable U.S. pure-play is Freshpet. The two biggest players of all — Mars Petcare and Diamond Pet Foods — are privately held, so much of the industry is only reachable through private equity, private credit, or direct ownership.

2. What it is and how it's structured

Scope. NAICS 311111 is the manufacturing of dog and cat food and treats. Census defines it as establishments primarily making dog and cat food from grains, oilseed-mill products, meat products, and similar inputs — including canned, dry, frozen, and semi-moist food and feed supplements.[2] It includes company-owned brand plants, private-label production (store brands), and contract or "co-manufacturing" (making product to another company's recipe).

What it excludes — important for sizing the industry correctly:

• Other Animal Food Manufacturing (NAICS 311119) — livestock, poultry, and feed for pets other than dogs and cats (birds, fish, rabbits, horses).[2]
• Animal slaughter for feed (NAICS 31161) — the suppliers of meat-and-bone meal and animal fats that feed into pet food.
• Dog and cat vitamins and minerals (NAICS 32541) — when manufactured as stand-alone supplements rather than as food.[2]
• Pet and Pet Supplies Retailers (NAICS 459910) — Petco, PetSmart, and the pet aisle at grocery/mass.
• Veterinary Services (NAICS 541940) and pet e-commerce (a retail/logistics activity, e.g. Chewy), which sell pet food but do not make it.

How the plants work. The basic model depends on format. Dry and semi-moist: ingredients are ground and blended with meat, fats, water, and steam, cooked through an extruder, cut into kibble, dried, coated with flavors or fats, and cooled. Wet food: requires filling and sealing cans, trays, or pouches and thermal sterilization; FDA subjects canned pet food to low-acid canned-food rules. Fresh products: use refrigerated ingredients, lower-temperature cooking, and in some cases high-pressure processing, followed by cold-chain distribution. Freeze-dried, dehydrated, and raw products have different preservation and pathogen-control requirements.[3] Moisture makes format comparisons deceptive: FDA notes canned food is typically 75%–78% moisture while dry food is typically 10%–12%, so nutrient claims must be converted to a dry-matter basis before comparing.[4]

Ownership mix. This is a concentrated, capital-intensive manufacturing base — extrusion lines, retort canning, freezers, and strict food-safety systems mean high fixed costs and few micro-operators. Brand ownership and manufacturing are not identical: major brands often own plants, but contract manufacturers also make national brands, emerging brands, and retailer private labels. This creates several business models: branded owner-manufacturer, branded asset-light marketer, private-label/co-manufacturer, and vertically integrated fresh-food producer. The economics and valuation of those models differ substantially.

3. How big it is

Our federal figures measure the industry at the factory gate — the value of what U.S. plants ship, before retail markup:

Two things stand out. First, revenue per employee is very high — about $1 million of shipments per worker — a signature of a highly automated, machine-run industry rather than a labor-intensive one. Second, the factory-gate figure (~$31.5B, 2023) is well below the widely quoted retail pet-food numbers of roughly $43–52 billion for 2024.[9][10] That gap is not a data error: retail sales add wholesale and store markups, include imported product (a large share of premium wet food is canned in Thailand and elsewhere), and cover a later, higher-priced year. APPA's headline $158 billion of total U.S. pet-industry spending in 2025 is not the market size of dog and cat food manufacturing — it includes veterinary care, services, supplies, and other categories.[1]

On the undercount question: unlike industries dominated by tiny sole proprietors or by government, 311111 is not materially undercounted by the federal business statistics — it is a small number of large, capital-intensive plants, and the Census captures them well. The real caveat runs the other way: U.S. manufacturing output understates U.S. consumption, because Americans also buy a lot of imported pet food (roughly $2.4 billion of imports in a recent year).[11]

Input intensity. A Pet Food Institute-sponsored study estimated that U.S. dog and cat food and treats used 9.3 million tons of ingredients worth $13.2 billion in 2024. Chicken products accounted for 2.2 million tons, grains 1.8 million, milled grains 1.6 million, and beef products 1.3 million.[12] (This is an industry-sponsored, model-based study using retail data and label reconstruction; its food-and-treat universe is broader than Census NAICS shipments, but it is useful evidence of input intensity.)

4. The investable universe

There is no clean public pure-play for the whole industry; exposure is mostly embedded in larger companies. Approximate scale below refers to pet-food revenue unless noted.

Notes for public-market investors: Nestlé's pet arm is large but is only ~20% of a much bigger company; Colgate is the closest "pure-ish" large-cap read on premium pet nutrition, since Hill's now drives roughly a quarter of group sales and has been its fastest grower.[14] Freshpet is the one liquid U.S. pure-play, but it is a growth stock, not a defensive one — it represents the fresh/refrigerated niche rather than the whole category. Its market value has swung violently (from roughly $7.7B early in 2025 to under $3B later in the year).[19]

ETF exposure: The ProShares Pet Care ETF (PAWZ) offers diversified pet exposure, not a pet-food-manufacturing portfolio. As of July 2026, Freshpet was ~11% and Nestlé ~4% of the fund; other large holdings were retailers and veterinary-health companies. Expense ratio: 0.50%.[20]

Major private/other owners (not investable in public markets):

• Mars Petcare — the private Mars family business; ~$22B global pet revenue, brands include Pedigree, Royal Canin, Iams, Nutro, Whiskas, Sheba, Cesar, Temptations, and (via its Champion Petfoods acquisition) Orijen and Acana.[13]
• Diamond Pet Foods (Schell & Kampeter) — family-owned, seven U.S. plants, own brands (Diamond, Taste of the Wild) plus heavy private-label/contract volume.[21]
• Simmons Pet Food — the leading North American private-label and contract maker of wet pet food.[21]
• Other contract manufacturers — Alphia, Sunshine Mills, C.J. Foods.[22]
• Challenger/DTC brands — The Farmer's Dog, Ollie, Nom Nom (fresh, subscription-first), typically PE/VC-backed.

5. How the money works

Owners in this industry make money the way branded and contract manufacturers do — the levers are volume, price/mix, input costs, and plant utilization:

• Recurring, sticky demand. A pet on a given food eats it daily and owners rarely switch (vets warn against abrupt diet changes). That produces razor-and-blade-like repeat revenue and low volume volatility.
• Price and mix (premiumization). The biggest profit driver over the past decade has been owners trading up — from grocery brands to premium, natural, grain-inclusive/grain-free, "human-grade," fresh, and functional foods (dental, joint, weight, gut health, life-stage/breed-specific). APPA found that 41% of dog owners and 38% of cat owners purchased premium food in 2024. Mixers and toppers were purchased by 16% of dog owners and 19% of cat owners, increases of 129% and 138%, respectively, from 2018.[23] Mix shift lifts average selling prices faster than volume.
• Input costs set the gross margin. Agricultural ingredients dominate variable cost, followed by packaging, freight, energy, plant labor, quality control, and retailer trade spending. The main cost buckets are animal proteins and by-product meals (poultry, beef, fish), grains (corn, wheat, rice) and pulses, fats, added vitamins/minerals, and packaging — cans and aluminum for wet food, pouches for premium. Producer-level pet-food prices rose ~34% from late 2018 to late 2025, a bit faster than the ~27% rise at retail, reflecting exactly these pressures.[24] Colgate identifies poultry, corn, soybeans, tallow, pulp, and packaging resins among its volatile inputs and notes that Hill's uses limited commodity hedging, generally with maturities no longer than 12 months.[14]
• Scale and utilization. With high fixed costs (extrusion, retort, drying, food-safety systems, warehouses, packaging lines), filling a plant's capacity is what turns volume into operating leverage. High utilization absorbs depreciation and overhead; excess capacity, SKU proliferation, and frequent changeovers do the opposite. Contract manufacturers (Diamond, Simmons, Alphia) earn thinner margins on high throughput; branded owners earn fatter margins on pricing power.
• Channel matters to margin. The vet channel (Hill's Prescription Diet) and premium specialty carry the richest margins; grocery/mass and private label are higher-volume, lower-margin. Retailer power is a countervailing force — Walmart, Costco, Chewy, and Amazon private labels squeeze branded margins.
• Fresh is a different capital model. Freshpet spends heavily up front — building "Freshpet Fridges" in stores and new refrigerated "kitchens" — trading years of capex and thin early margins for a fast-growing, high-price niche. Cold-chain and company-owned retail refrigerators make it structurally different from conventional kibble.[18]

What strong branded franchises can earn. Public disclosures show segment economics, but not an industry-average margin: Hill's reported 2025 global sales of $4.6 billion and operating profit of $1.1 billion — a 23% segment margin — with pricing up 3% and volume down slightly as raw and packaging inflation remained a headwind.[14] General Mills' North America Pet segment produced fiscal-2025 sales of $2.5 billion and segment operating profit of $501 million — approximately 20% of sales — with cost savings supporting profit while input inflation, additional media spending, and weaker price/mix offset part of the benefit.[15] The gap between Census revenue and operating-expense estimates should not be labeled EBIT or EBITDA: Census definitions, survey coverage, and consolidation conventions differ from GAAP financial statements.

A useful tell: the category is defensive but not acyclical. Pets must be fed, yet consumers can switch from premium to mainstream or private label, reduce treats and toppers, or favor cheaper dry food. General Mills' fiscal-2025 organic pet sales were essentially flat despite higher reported sales from acquisitions.[15]

6. What drives demand

• Pet population and household penetration. About 95 million U.S. households own a pet; 53% own a dog and 39% a cat.[1] This is the base load.
• Humanization. Around 90% of owners regard pets as family, which reframes food as a health-and-love purchase rather than a commodity[25] — the core reason people pay premium prices.
• Demographics. Millennial and Gen Z pet parents, delayed family formation, and more single-person households all raise per-pet spend and premium adoption.
• Non-discretionary base, discretionary top. Feeding itself is recession-resistant, but the premium tier is discretionary — in downturns owners trade down and private label gains share.
• Channel shift. E-commerce and auto-ship subscriptions (Chewy, Amazon, DTC) have lowered the friction of repeat buying and enabled niche brands, although e-commerce increases fulfillment expense for bulky, low-value-per-pound products.
• Category rotation. Recently, cat food and fresh/frozen have grown faster than mainstream dry dog food.[9] Fresh, refrigerated, freeze-dried, and raw formats are taking shelf and freezer space from conventional formats, although their economics are harder: shorter shelf life, more expensive ingredients, pathogen risk, and specialized distribution.

7. Regulation

Pet food is regulated as animal food, primarily by the FDA (U.S. Food and Drug Administration) under the FD&C Act (Federal Food, Drug, and Cosmetic Act): product must be safe, made under sanitary conditions, free of harmful substances, and truthfully labeled.[26] Common ingredients (meat, poultry, grains) need no pre-market approval, but additives are regulated.

• FSMA (Food Safety Modernization Act). The Preventive Controls for Animal Food rule requires covered facilities to register with FDA, conduct hazard analysis, implement preventive controls, and follow current good manufacturing practices (cGMP) — a real compliance cost that favors scale. FDA and state partners can inspect facilities, request or mandate recalls, detain product, suspend registrations, seize goods, or seek injunctions and criminal penalties.[26][27]
• AAFCO (Association of American Feed Control Officials). AAFCO writes the model nutrient profiles, feeding-trial protocols, ingredient definitions, and label rules that states adopt and enforce; AAFCO itself has no legal authority and does not approve or certify brands.[28] "Complete and balanced" means a product meets an AAFCO nutrient profile or passes an AAFCO feeding trial; it is not a general FDA endorsement.[4] A notable change: the FDA–AAFCO memorandum of understanding on ingredient definitions expired October 1, 2024, shifting how new ingredients get vetted and adding some near-term uncertainty for novel ingredients.[28]
• State and export layers. Products are registered and labeled state-by-state; the FTC polices advertising claims; and exports run through USDA/APHIS certification.[11]
• Safety events. The relevant hazards include Salmonella, Listeria, and other bacteria; mycotoxins such as aflatoxin; nutrient under- or over-formulation; foreign material; spoilage; and supplier adulteration. Raw food is especially exposed: an FDA study found commercially available raw pet food more likely than other tested formats to contain disease-causing bacteria.[29] Recalls and the FDA's 2018–2019 inquiry linking some grain-free diets to canine heart disease (DCM, dilated cardiomyopathy) show how regulatory attention can reshape demand and force costly reformulation.[30]

8. Competitive dynamics and consolidation

The federal data show a concentrated manufacturing base: the top 4 firms make 56.6% of shipments, the top 8 ~68%, and the top 20 ~83% (the industry's Herfindahl-Hirschman index is suppressed in the source).[31] This measures U.S. production and omits import competition; it also does not identify the four companies. At the brand/retail level, concentration is even more visible — four consumer-goods giants (Mars, Nestlé Purina, Colgate/Hill's, General Mills/Blue Buffalo) dominate across price points.[13]

Below the giants sit two other tiers:

• Contract and private-label manufacturers (Diamond, Simmons, Alphia, C.J. Foods) that produce for retailers and challenger brands. Private label has been taking share — private-label pet sales reached ~$5.5B in the year to mid-2025 and grew faster than national brands.[32]
• Challenger/DTC and fresh brands (Freshpet, The Farmer's Dog, Ollie, Nom Nom) attacking the premium end.

Consolidation is a constant. Recent moves include Post Holdings' ~$1.2 billion purchase of J.M. Smucker's value pet brands in 2023 (Nutrish, 9Lives, Kibbles 'n Bits, Nature's Recipe, Gravy Train, and associated private-label operations — brands that had generated $1.4 billion of sales in the prior year) plus Perfection Pet Foods,[17][33] Mars's acquisition of Champion Petfoods (Orijen/Acana), and a string of premium/treat deals. M&A cooled in 2024–2025 under higher rates, tariffs, and cost inflation, but analysts expect a modest rebound as rates stabilize.[32] Retailer power is a countervailing force — Walmart, Costco, Chewy, and Amazon private labels squeeze branded margins.

9. Risks

• Input-cost inflation — animal protein, grain, fats, vitamins, energy, freight, and especially packaging/aluminum; elevated manufacturing costs have become a new baseline.[24]
• Tariffs on imported ingredients and packaging (cans, pouches) — a live 2025 risk that can compress margins or force price increases.[24]
• Private-label trade-down in downturns, pressuring branded volume and pricing.[32]
• Recalls and product liability — contamination events carry outsized reputational and financial damage in a category built on pet health. Raw formats carry elevated pathogen risk.[29]
• Regulatory uncertainty — the post-2024 shift in FDA/AAFCO ingredient review, the state-by-state patchwork, and any move toward mandatory standards.[28]
• Demand maturity — the U.S. pet population plateaued after the pandemic adoption surge; volume growth is now low-single-digit, so results lean heavily on premiumization holding up.[9]
• Fads and stranded inventory — grain-free/DCM, raw, and novel-protein swings can force reformulation and write-downs.[30]
• Capital intensity of fresh — freezer/kitchen buildouts (Freshpet) carry execution and margin risk if growth slows; fresh formats add spoilage, refrigeration failure, and returns.[18]
• Distribution losses — because retailers can reset shelves faster than manufacturers can close plants, losing shelf space creates particularly severe negative operating leverage.
• Counterparty risk — contract manufacturing reduces fixed capital but introduces capacity, quality-control, and supplier risks.

10. How to invest and the outlook

Public routes. For a defensive, dividend-style read on premium pet nutrition, the diversified large-caps are the practical vehicles — Colgate-Palmolive (Hill's is now ~a quarter of the company and its growth engine),[14] General Mills (Blue Buffalo), J.M. Smucker (Meow Mix, Milk-Bone), Post Holdings, and Nestlé (Purina, via ADRs). For pure growth exposure to the fastest-growing niche, Freshpet is the only sizable U.S. pure-play — higher reward, higher volatility, and no dividend.[18][19]

Private routes. Because Mars Petcare, Diamond, Simmons, and the DTC challengers are all private, the richest part of the industry is reached through private equity and venture (premium, fresh, and functional brands have drawn heavy investor interest), private credit to mid-market manufacturers, or direct ownership of a contract/private-label plant — a capacity-utilization, cost-plus business rather than a brand bet. In underwriting a private manufacturer, owned capacity, utilization, customer concentration, recall history, supplier qualification, retailer authorizations, and working-capital requirements matter as much as reported brand sales.

Near-term drivers to watch (forward-looking):

• Input costs: a record 2025–26 U.S. corn crop is keeping grain soft, a tailwind to margins, but proteins and packaging remain sticky and tariffs are a wildcard.[24]
• Premium vs. value: whether owners keep trading up (bullish for branded margins) or keep shifting to private label (bearish).[32]
• Fresh and functional remain the fastest-growing formats; cat is outgrowing dog.[9]
• Exports: U.S. pet-food exports reached ~$2.5B in 2024, led by Canada (~$1.2B) with China growing double digits — a real, if modest, growth outlet for domestic plants.[11]
• M&A: a rebound as interest rates and tariff paths clarify.[32]

Bottom line (judgment): a stable, cash-generative, mildly-growing industry with an unusually defensive demand base and a premiumization story that is maturing but not exhausted. The best economics accrue to scale brands and to whoever controls premium/fresh; the main threats are input/packaging costs, a value-seeking consumer, and regulatory-safety shocks. Most investors will own it inside a diversified consumer name rather than as a stand-alone bet.
