Dogs and cats have very different food choices, as do their tastes and nutritional needs. Generally speaking, cat food is richer in animal protein and fat than dog food, and contains more vitamins, minerals and amino acids that cats need. In comparison, dog food requires more carbohydrates and vegetables to provide more energy and fiber.
Therefore, dogs may not like to eat cat food because the taste and nutritional formula do not suit their tastes and nutritional needs. In addition, some cat food may contain ingredients that are harmful to dogs, such as large amounts of vitamin A, so cat food is not recommended as a dog's staple food.
