Q: As the ingredients contained in this food are not the optimal food sources essential to a cat's well being, I don't actually feed my cats this dry food. Corn is the first ingredient, which is a food my cats really don't crave. There is a meat source as the second ingredient, but unfortunately, it is a by-product. Although there are a couple of other meat sources listed in the ingredients, the addition of artificial preservatives and coloring make this cat food a less than desirable food staple for any cat. However, the Amazon price is good and with Amazon prime 2-day free shipping directly to work, this is a very convenient food for the shop cats I feed. While the ingredients aren't the best, feeding it along with canned food, it is a balanced diet and seems to keep the shop cats healthy.
