The maker

Who makes this — and how they back it up

The five questions the WSAVA nutrition guidelines tell you to ask a pet-food company. Every answer is sourced or marked as an undisclosed gap — never guessed. This is the "is it made competently?" axis that star-rating sites skip.

Owns its manufacturing Owns its plants

Iams is produced at Mars Petcare's owned/operated Mattoon, Illinois plant.

AAFCO feeding trials Undisclosed

No feeding-trial AAFCO statement found on the 70 labels we’ve verified for this brand, and no company-wide claim was found either. Most pet foods are only "formulated to meet" AAFCO profiles (a paper calculation) rather than fed to real animals in trials — this is common, not necessarily a red flag.

Publishes quality-control testing Not found

no QC process described.

Peer-reviewed research Yes — sourced
