The common claim vs. the evidence

What’s commonly claimed, and what the evidence supports

Reviewers who answer 'who makes Kirkland cat food' usually name Diamond Pet Foods, but that comes from the dry line — Costco's own pet FAQ credits Diamond only with 'all of the dry foods,' and Diamond runs limited canning. For the wet pâté specifically, the only name in circulation is Simmons Pet Food, one of the largest US contract wet-pet-food packers, but it traces to a single unsourced 2022 blog comment ('seems to be manufactured by Simmons'); no tier 1–5 evidence supports it. No public record identifies who cans Kirkland's wet cat food.

What we searched

Evidence & sources

Costco does not disclose its suppliers, and no tier 1–5 source names the maker of this product. Below are the databases and records we checked, and what each one returned.

What we checked: 6 databases & records, as of July 5, 2026

FDA / FSIS recall database (Kirkland canned/wet cat food, all years) July 5, 2026

No recall names a co-packer for Kirkland wet/canned cat food. The 2007 American Nutrition melamine recall named Kirkland canned DOG food only (its CANNED CAT FOOD section listed other brands, no Kirkland cat product); the 2012 Diamond recall covered dry cat formulas, not cans.

Costco own pet FAQ (kirkland-signature-pet-faqs.html, 2025-02-28 snapshot) July 5, 2026

Costco scopes its Diamond Pet Foods statement to 'all of the dry foods'; the FAQ says nothing about who cans the wet cat food, so the dry attribution does not carry over.

Costco's manufacturer field / manufacturer-name filter on Costco.com product pages (Wayback CDX) July 5, 2026

No archived Costco wet-cat-food product page exposing Costco's manufacturer field was found; live costco.com blocks automated fetches — reading the live pâté product page facet still needs a manual browser check.

Review sites & community (cats.com, catfooddb, TheCatSite, FDMB) July 5, 2026

The only company ever named for the wet cat food is Simmons Pet Food, and it traces to a single unsourced 2022 reader-comment reply on cats.com ('Kirkland's wet food seems to be manufactured by Simmons') — a tier-6 rumor with no citation, not an attribution.

Trade press (PetfoodIndustry, PetFoodProcessing) July 5, 2026

No article identifies a co-packer for Kirkland wet cat food. Simmons Pet Food is documented there as a leading US contract wet-pet-food manufacturer, but nothing ties it to the Kirkland pâté.

ImportYeti (US customs / bill-of-lading) July 5, 2026

No useful match; canned cat food for a US private label is domestically packed and Costco masks shipments via freight forwarders, so customs data yields no reliable co-packer.

Frequently asked

Who makes Kirkland Signature wet (canned) cat food?

No reliable public evidence identifies the maker of Kirkland Signature wet cat food. Costco's own pet FAQ credits Diamond Pet Foods with the dry foods only, so the popular 'Diamond makes it' answer does not cover the pâté cans. The only company ever floated for the wet cat food is Simmons Pet Food — a major US wet-food co-packer — but that traces to one unsourced 2022 reader comment, not to any recall, label, or Costco statement.

Does Diamond Pet Foods make the Kirkland cat pâté?

There is no public evidence that it does. Costco's FAQ statement about Diamond Pet Foods is limited to the dry foods, and the wet cat food is a separate product with its own supply chain. The 2007 American Nutrition recall that named Kirkland canned dog food did not include any Kirkland canned cat product, so it ties no co-packer to the pâté.

Is Kirkland wet cat food made by Simmons?

That claim circulates online, but it is not verified. It traces to a single 2022 blog comment that said the wet food 'seems to be' from Simmons Pet Food, with no source; Simmons is one of the largest US contract wet-food packers, which makes it a plausible candidate, but no recall, product label, or Costco page confirms it. We list the wet cat food as unknown until such evidence appears.
