Kirkland cat food has become a genuinely popular pick among Costco members, offering ingredient lists that read closer to premium pet specialty brands while carrying a much smaller price tag.
Like most Kirkland Signature products, the cat food line is not manufactured by Costco itself, but by an outside contract partner with real pet food manufacturing expertise.
Here is exactly who makes Kirkland cat food, where it comes from, and what real cat owners say once they have made the switch.

Who Really Makes Kirkland Cat Food
Kirkland cat food is manufactured by Diamond Pet Foods, a privately held, family owned pet food company founded in 1957 and headquartered in Meta, Missouri, which produces the Kirkland Signature dry and wet cat food formulas under contract for Costco, a relationship confirmed by Yahoo Finance coverage of Kirkland Signature suppliers.
This arrangement mirrors the same relationship Diamond Pet Foods holds with several other well known pet food brands, giving Costco access to established manufacturing expertise without operating its own dedicated pet food factory.
Kirkland Cat Food Manufacturing Locations
Diamond Pet Foods operates multiple production facilities across the United States, including plants in Arkansas, South Carolina, and California, and Kirkland cat food formulas are produced across this same manufacturing network.
Because Diamond Pet Foods owns and operates its facilities directly rather than outsourcing to third party co packers, Costco benefits from a manufacturing partner with direct oversight over the entire production process.
Why Kirkland Cat Food Punches Above Its Price Point
Kirkland cat food formulas frequently include higher protein content and fewer grain based fillers than typical grocery store cat food, positioning it closer to pet specialty store brands despite selling at a big box club store price.
This value positioning has made Kirkland one of the more frequently recommended budget premium options among cat owners looking to avoid paying pet specialty store markup for comparable ingredient quality.
What Owners Say About Kirkland Cat Food In Trustpilot And Reviews
Cat food review sites consistently rate Kirkland formulas well, with owners frequently citing improved coat condition and digestion after switching from cheaper grocery store brands, while Consumer Affairs reviews note the value is hard to match at the price point.
The most common criticism involves availability, since Kirkland cat food is only sold to Costco members, requiring a membership that some cat owners may not otherwise need.
Kirkland Cat Food Warranty And Customer Support
Kirkland cat food does not carry a traditional product warranty, but Costco backs all Kirkland Signature products with its standard member satisfaction guarantee and return policy.
Members with quality concerns about a specific Kirkland cat food product can return it to any Costco warehouse or contact Costco member services directly.

Is Kirkland Cat Food Really Good
Kirkland cat food delivers genuinely strong value, backed by an experienced manufacturing partner in Diamond Pet Foods and formulas that compare favorably to pricier pet specialty store brands.
The main limitation is availability, since a Costco membership is required to purchase it, which may not make sense for cat owners who otherwise have no reason to shop at Costco.
