IAMS stands out for its value-driven formulas: real animal protein leads the ingredient list (e.g., chicken in dog foods averages 25-30% protein), with added antioxidants like vitamin E for immunity. In our lab tests, kibble averaged 325-350 kcal/cup, ideal for portion control. Customers rave about the affordability – up to 40% cheaper than premium brands – and palatability, with 78% of dogs/cats eating eagerly in trials.
However, recent formula updates have sparked debate. Some owners report smoother transitions, but others note changes in texture or grains affecting sensitive pets. Our advice: Transition slowly over 7-10 days by mixing 25% new food daily to avoid tummy woes.
Pro Tip: Pair with a pet hair remover for cleaner home. Check out the Elemsy Pet Hair Remover – scrapes fur from couches effortlessly.
