I feed my little stray Angel Iams kitten food. I stopped using all Purina brands when Proctor and Gamble bought Purina.
I feed my adult cat Wellness, which is wonderful - no by-products and all natural. Innova and Wysong are also superior brands of cat food. Roxxi, my older cat gets bored with any food after a while and I have to find something new. The latest brand I bought is Evolve.
Be sure you change over very gradually when introducing a different brand of food.
Good luck...
