Mainstream pet-food producers commonly combine animal fats and meals with soy and wheat to create their products. By adding essential vitamins and minerals, they manage to produce a cost-effective and nutritionally adequate pellet for pets. However, the taste and appeal of these foods often leave much to be desired, leading to a product that both pets and their owners may find unappealing.
In her book "Gulp: Adventures on the Alimentary Canal," author Mary Roach highlights the reality of commercial pet food production. Despite being designed to meet nutritional needs, the resulting products are often seen as undesirable, raising questions about their overall quality and the palatability for the animals they aim to nourish.
