there have been so many asking questions about whats a good brand of commercial cat food.
The following is a link to a site by Dr. Lisa A Pierson DVM on her site she lists the better brands that are without wheat, soy and corn. They are prepared with MEAT as the primary ingredient and not meat by-products.
these prefered brands are also void of any questionable preservatives such as BHA, BHT and Ethoxyquin.
Her list is not comprehensive, its a few examples of some of the higher quality products available.
