Corn, high grain content and cheap sources of protein. All bad for cats.
To give you an example, my parents had a barn cat that was allergic to chicken protein. The vet gave us two options: MediCal food at $40.00 a bag (made with duck, not chicken) or Purina Cat Chow since its main protein source is soya. Chose the MediCal thank you very much!!
