Whiskas Catmilk Drink for Cats & Kittens - my cats *love* this! You can buy it at the grocery store, Walmart or pet stores. Contains taurine, an essential nutrient for a cat's heart and eye health. Easy to digest because it's 98% lactose-reduced. Contains no artificial colors or flavors. If your cat loves milk, it's much better to give them this instead of the milk we drink which can be hard for them to digest.
