Urban King Is our superb biologically appropriate real super food diet designed specifically for Cats & Kittens. Urban King is quick and easy to make and contains a balance unique for cats. When changing your cat to Urban King, please understand that commercial cat foods contain addictive flavoring additives (particularily the dry kibble) so it may take some time and patience to get your cat changed over to a 'real' food diet. We recommend discontinuing the dry food altogether and blend a little of the new food in with your cat's favorite canned cat food. Gradually increase the Urban King and decrease the canned food and in about a week or two your cat will have changed over. Please do not let your cat fast for more than one day.
