Because our diets are formulated to be species-specific, we don't recommend feeding our cat food to dogs (or dog food to cats) on a long-term basis. There are species-specific nutritional needs for both dogs and cats that we’ve developed into our Formulas.
Our cat foods have a higher protein content geared for a feline’s needs and are not optimized for canines. Our dog foods will not offer enough protein for a cat's long-term health. Additionally, there are feline-specific ingredients such as taurine that are not found in our canine varieties. Vitamin and mineral supplementation is geared toward each species in canine and feline varieties.
However, short-term feeding will be fine (i.e. a wrong bag purchased by mistake). For optimum results and for your pet’s long-term feeding regimen, we recommend feeding only the species-appropriate variety.
