I cook for my babies, Nina & Coby had really bad allergies. So I first switched to Solid Gold, It's pretty much like Innova, all natural and no by products, corn or chicken. As soon as I found out that the chicken and the corn were the cause of there allergies I started cooking for them, Meat, veggies and rice. They eat it in the morning and in the evening I give them a small amount of Solid Gold. Since I've changed there diet no more scratching.
