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.","structured_data":{"note":"The nutrient values in this topic are also available as structured data — faster and exact, no text parsing needed.","compare":"/api/v1/cross_compare?standards=AAFCO,FEDIAF,KFDA&species=dog&lifestage=adult&nutrient=protein&basis=DM","coverage":"Standards: AAFCO (year>=2014), FEDIAF (year>=2025), EU PARNUT (year>=2020), KFDA/NIAS Korea (year>=2024). species: dog|cat. lifestage: adult|GR (growth/puppy/kitten map to growth-reproduction). basis: DM|cal.","single":"/api/v1/nutrient?standard=AAFCO&year=2024&species=dog&lifestage=adult&nutrient=protein&basis=DM","batch":"/api/v1/batch_nutrient?standard=AAFCO&year=2024&species=dog&lifestage=adult&nutrients=protein,fat,calcium,phosphorus&basis=DM"}}
