The sustainable pet food dilemma

Every aspect of pet ownership has some environmental footprint, whether it is the food they eat, the toys they play with or the faeces they produce. Some of these environmental factors can be influenced by pet owners and healthcare providers, while others cannot. Studies considering the most eco-friendly pets ranked tortoises, rats and mice among the lowest impact pets to keep, with large breed dogs and horses the least eco friendly. These ratings were based on a variety of factors, including the pet's dietary requirements, water requirement, lifespan, transportation costs, grooming and accessories, waste production and likelihood to require veterinary medicines. This article concentrates on the impact of the food source provided to the most popular pets: cats and dogs.
