A cat food nutrient profile table appears in the 2015 Pet Food Report (local extraction partial, some values missing). From 2016 onward the values carried forward: the AAFCO 2024 Official Publication is a carry-over of the 2016 revisions, and the profiles were last substantively updated in 2014/2016. Protein minimums remained 22.5% DM (dog G&R) and 18% DM (dog adult) throughout. Cat minimums remained 30% DM (G&R) and 26% DM (adult) throughout.\n","sources":["AAFCO wp-content/uploads PDF — AAFCO 2013 to 2015 evolution (retrieved 2026-07-21)"],"source":{"authority":"AAFCO wp-content/uploads PDF","title":"AAFCO 2013 to 2015 evolution","url":"https://www.aafco.org/","retrieved":"2026-07-21","ref":"","doc_type":"official source","source_document":"AAFCO Model Pet Food Regulations","verification_file":""},"source_document":"AAFCO Model Pet Food Regulations","source_file":"","trust":{"authority_tier":"T1","fidelity":"verbatim","license":null,"display_grade":"A"},"tokens_estimated":150,"generated_at":"2026-07-19","tip":"Use /api/v1/topics to discover more topics. /api/v1/nutrient for precise single-point queries. /api/v1/cross_compare for 2-3 standard comparisons."}
