Looking through the Nutrisource web sight It seems to indicat a mostly plant base. The only animal products listed are a protein from feathers and hair. That and maybe some fat with the source not listed.
It seems like the protein components are from a chicken processing plants scrap pile.
I bet when I start feeding the Aquamax 500 they go nuts over it.
Protein from feathers and hair, while protein, is not digestible!
