Who makes Kirkland Signature Wet (Canned) Cat Food, Pâté?
No reliable public evidence identifies the manufacturer of Kirkland Signature Wet (Canned) Cat Food, Pâté as of July 5, 2026.
The common claim
What most answers say — 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.
Evidence & sources
Costco does not disclose its suppliers, and no tier 1–5 source names the maker of this product. Below is the documented search — every database and record we checked, and what each one returned.
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.com PDP mfName / manufacturername facet (Wayback CDX) July 5, 2026
No archived Costco wet-cat-food product page exposing an mfName/manufacturername field was found; live costco.com blocks automated fetches — reading the live pâté PDP facet is a browser follow-up for Ian.
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.
