It's very simple! Feed your cat, ferret, or small dog from this package every day and they will get everything they need. BARFmenu Complete is a 5-kilogram box containing 5 different BARFmenu mixes. BARFmenu Complete is a complete mix, so your pet gets all the necessary nutrients. BARFmenu Complete contains no fragrances, colors, flavors, and/or preservatives. BARFmenu is gluten-free (so no rice or grains). Suitable for kittens, puppies, small dog breeds, cats, and ferrets. Why can the dog and/or ferret eat the cat food? A cat is an obligate carnivore, which means: a pure meat-eater (so no rice and vegetables, etc.). Taurine must be obtained by the cat from its food, unlike the dog which produces its own taurine. Taurine is naturally present in meat, especially in the heart. To guarantee sufficient taurine, the percentage of heart in the 250g packages has been slightly increased. In addition to adding a higher percentage of heart for the taurine requirement, the meat, organs, and bones are ground more finely, so that kittens, puppies, small dog breeds, and ferrets can also eat it.
