We, humans always think that we have a control on our pets when it comes to their diet. But think of all these years of what you have been feeding your cat, mostly grains, unnamed meat meals and probably just chicken flavour. In fact, we also took our eating habits to them like if a person is vegetarian and his cat will also be a vegetarian which is absolutely not good for a carnivore like cats. Cats need enormous amount of meat in their diet in order to get a complete nutrition. Also, serving the same diet for extended periods of time is also not good. The key to a proper nutrition is by changing their diet quite often by which your cat will get different nutrients from different meat recipes and stays healthy and happy for years to come.
