IAMS Cat Food Summary

What is IAMS Cat Food?

IAMS is a pet food brand that is owned by Mars, Inc. However, their European branch is owned and managed by Spectrum Brands.

IAMS was first introduced in 1946 by Paul Iams, who was a self-taught animal nutritionist. Initially, Iams started selling high-protein and high-fat dog food. Soon afterward, in the 1950s, it released the first dry dog food, which was made specifically from animal-based protein. Following this, the brand expanded into the cat food business as well.

Procter & Gamble (P&G) purchased the brand in 1999. This helped IAMS cat food reach a global audience of 70 countries.

However, in 2014, P&G released a statement that Iams, Eukanuba, and Natura would be sold to Mars, Incorporated. But it would retain ownership of the European market.

By the end of 2014, P&G struck a deal with Spectrum Brands and sold them the European division. Spectrum Brands is also the owner of One Earth pet food, Furminator, LitterMaid, and Nature’s Miracle.

Where is IAMS Cat Food Made?

IAMS cat food is primarily manufactured in the USA. Their facilities are located mainly in Ohio, Nebraska, and North Carolina.

The brand’s European division has its plant in Coevorden, a city in Drenthe, Netherlands.

How is IAMS Cat Food Made?

IAMS is not very open about the source of its ingredients. However, all the subsidiaries that are associated with Mars are a part of Mars’ Responsible Sourcing program. Additionally, they also follow Mars’ Supplier Code of Conduct.

Therefore, it is easy to conclude that IAMS cat food uses human-grade products to manufacture pet foods.

Is IAMS Cat Food Good for Cats?
