At our shelter we use high quality cat food. The most recent one we started was Innova EVO cat (they make a ferret blend, too. More expensive and stores don't carry it in our area, but ingredients are almost identical.) The other one I mix with is Felidae Cat & Kitten, white bag with green cat eyes. I have also used Natural Balance Cat, the bag with the pink top border and sky background. But narrowed down to two after a "taste test". You can find these brands online and find out who sells them in your area. Innova EVO www.naturapet.com or 1-800-532-7261 Felidae Cat www.canidae.com or 1-800-398-1600 Natural Balance Cat www.naturalbalanceinc.com or 1-800-829-4493 Make a slow change. I have the best luck with just putting a few pieces of the new stuff on the floor next to the bowl. They are curious and start nibbling. Then later will gradually mix into current food. All my guys went for the Innova EVO and its the my cats favorite, too. Good Luck, Liz ...in the Company of Ferrets, Inc. www.ferretasylum.com [Posted in FML 5562]
