I want more information about feeding good cat food?

First there are allot of good brands out there, what you want to do is look on the back of the bag. Read the ingredients. If you see corn soy wheat and animal by-products put that bag down.. Allot of cheep pet food company's use lots of fillers in the food, like grains cereals. So just remember to read the ingredients on the back of the bag if you see the word by-products put the bag down.
