Who makes Kirkland Signature Super Premium Dry Cat Food?
As of July 5, 2026, the manufacturer of Kirkland Signature Super Premium Dry Cat Food is Diamond Pet Foods, per recall notice evidence.
The common claim
What most answers say — and what the evidence supports
Top-ranking answers near-uniformly say Diamond Pet Foods makes Kirkland cat food, and for the dry formulas the consensus is supported — Costco's own pet-food FAQ covers all Kirkland Signature dry foods, and the FDA's 2012 recall notice named two Kirkland cat formulas (Maintenance Cat Chicken & Rice, Healthy Weight Cat) among Diamond's recalled products. Note this page covers the dry food only; the canned/wet Kirkland cat food is a separate product with its own supply chain.
Evidence & sources
Every source is graded on the six-tier rubric and archived, so the citation holds even if the original moves or paywalls. The tier badge grades the source; the status grades our confidence in the maker.
Tier 2
FDA recall notice names two Kirkland cat formulas among the Diamond Pet Foods products recalled from its Gaston, S.C. plant: 'Kirkland Signature Super Premium Maintenance Cat Chicken & Rice Formula' and 'Kirkland Signature Super Premium Healthy Weight Cat Formula' — direct co-packer naming for the dry cat food specifically, but it evidences 2012, not the present; URL is FDA's official archive-it copy of the retired fda.gov page.
Tier 4
Costco's own FAQ: 'All of the dry foods are made by Diamond Pet Foods in five company owned manufacturing facilities, all in the United States.' The statement covers every Kirkland Signature dry pet food, cat formulas included; wording verified from the 2025-02-28 snapshot because the live page blocks automated fetches — recheck the live page at next verification.
