Iams
ProActive Health Healthy Adult Original with Chicken
Excellent cost per calorie and a chicken-first formula with taurine declared. The official page did not expose a verbatim AAFCO statement; chicken by-product meal sits very high in the ingredient list.

Regulatory history
Purina ONE
Tender Selects Blend with Real Chicken
Strong value and solid cat-relevant nutrition, including feeding-trial substantiation and explicit taurine. The ingredient panel is busy and sensitivity-heavy, with chicken, beef fat, soy, corn, and legumes prominent.
