Paul Iams, an animal nutritionist, founded Iams in 1946 in Dayton, Ohio. Iams had previously worked as a dog handler and nutritionist and was dissatisfied with the quality of commercial pet foods available at the time, which were largely composed of grain fillers and meat by-products. He developed a dog food formula using high-quality animal protein as the primary ingredient, which he called Iams 999.
The company grew slowly through the 1950s and 1960s, selling primarily through veterinary clinics and specialty pet stores rather than mass-market retailers. This distribution strategy positioned Iams as a premium, professionally recommended brand and built loyalty among veterinarians and breeders.
In 1975, Paul Iams sold the company to Clay Mathile, who had joined Iams in 1970 as a general manager. Mathile led the company through a period of significant growth, expanding into cat food, international markets, and new manufacturing facilities. Under Mathile's leadership, Iams grew from approximately $100 million in revenue to over $1 billion by the late 1990s.
Procter and Gamble acquired Iams in 1999 for $2.1 billion, marking P&G's entry into the pet care industry. Under P&G ownership, Iams expanded its distribution to mass-market retailers including Walmart and Target, moving away from the brand's traditional specialty channel focus. This expansion increased sales volume but drew criticism from some long-time customers and veterinarians who felt the brand's premium positioning was being diluted.
In 2014, P&G sold Iams, Eukanuba, and its European pet care operations to Mars for $2.9 billion. P&G retained its North American pet care business briefly before selling the remaining operations to Spectrum Brands in 2015. The Mars acquisition brought Iams into the world's largest pet care portfolio, alongside Royal Canin, Pedigree, and Whiskas.
Under Mars ownership, Iams has been repositioned as a mid-premium brand, sitting below Royal Canin (veterinary and breed-specific) and above Pedigree (mass-market). The brand has focused on its Proactive Health line, which includes formulas for different life stages, sizes, and health needs. Iams products are sold through mass-market retailers, pet specialty stores, and online channels.

What was Mars's largest acquisition?
Mars's largest acquisition was the $36 billion purchase of Kellanova, completed on December 11, 2025. Kellanova's portfolio included Pringles, Cheez-It, Pop-Tarts, RXBAR, and Kellogg's international cereal brands. The deal created a combined Mars Snacking division generating approximately $36 billion in annual revenue. Prior to Kellanova, Mars's largest acquisition was the approximately $23 billion purchase of Wrigley in 2008.
What is Mars's annual revenue?
Mars generates approximately $65 billion in annual revenue (FY2025, estimated). The company does not publicly disclose detailed financial results because it is privately held. Revenue estimates come from company press releases, credit rating agencies, and reputable business press. Following the Kellanova acquisition, Mars's snacking division alone generates approximately $36 billion in annual revenue.
Iams operates under Mars, Incorporated's sustainability framework. Mars has committed to net zero greenhouse gas emissions across its full value chain by 2050, with interim targets for 2030. The company reports progress annually in its Principles in Action report.
Mars Petcare has established specific sustainability initiatives for its pet food brands, including sustainable sourcing of fish (through Marine Stewardship Council certification), responsible meat sourcing, and packaging reduction targets. Iams packaging has been redesigned to reduce plastic content, and Mars has committed to 100% recyclable, reusable, or compostable packaging by 2025.
Iams ingredients are sourced from suppliers who must meet Mars' supplier code of conduct, which covers environmental standards, labor practices, and animal welfare. Mars conducts supplier audits and publishes compliance data in its annual report. The company sources chicken, turkey, and lamb from suppliers in the United States and Europe.
Animal welfare is a core concern for Mars Petcare. The company has established animal welfare standards for its ingredient suppliers and conducts welfare audits at supplier facilities. Mars has also committed to eliminating cage housing for laying hens in its supply chain by 2025.
Iams supports pet adoption programs and animal shelter partnerships through Mars Petcare's corporate giving initiatives. The brand has partnered with organizations including the American Humane Society and local animal shelters to promote pet adoption and responsible pet ownership.
Iams is recognized as one of the few pet food brands that meets World Small Animal Veterinary Association (WSAVA) guidelines for pet nutrition. This recognition places Iams alongside Royal Canin, Hill's Science Diet, Purina Pro Plan, and Eukanuba as brands that meet the highest standards for pet food formulation, nutritional adequacy, and manufacturing quality control.
The brand has received veterinary endorsements and recommendations from veterinary professionals for its science-based nutrition approach. Iams employs veterinary nutritionists and conducts feeding trials to support its nutritional claims.
Consumer publications including Consumer Reports and pet food review sites have generally rated Iams favorably for nutritional quality and value. The brand's Proactive Health line has been recognized for providing balanced nutrition at accessible price points.
Iams' most significant recall occurred in August 2013 when the company voluntarily recalled several dry dog food and cat food products due to potential Salmonella contamination. The recall affected specific production lots and was initiated after routine testing identified possible contamination. Iams worked with the FDA to remove affected products and implemented enhanced quality control measures. No illnesses were reported in connection with the recall.
Iams has faced criticism from some pet owners and pet nutrition advocates regarding the use of corn, soy, and meat by-products in its formulations. Critics argue these ingredients are lower quality than whole meat ingredients. Iams maintains that all ingredients meet nutritional standards and are included based on scientific research supporting their nutritional value. The brand's compliance with WSAVA guidelines supports this position.
The brand's ownership changes have prompted consumer concerns about potential changes in ingredient quality. The transition from independent ownership to P&G (1999) and then to Mars (2014) led some customers to question whether product quality remained consistent. Iams maintains that its nutritional standards and quality control have been maintained through both ownership transitions, and the brand's continued WSAVA compliance supports this claim.
Iams has been involved in broader industry debates about grain-free diets and their potential link to dilated cardiomyopathy (DCM) in dogs. The FDA investigated a potential connection between grain-free diets and DCM between 2018 and 2021. Iams, which includes grains in most of its formulations, was not named in the investigation. The brand has used the DCM concern to differentiate its grain-inclusive formulas from grain-free competitors.
