This article does not deliver at all on its purported topic. It is an interview with a veterinarian who, in response to one question, says vaguely:<p>"Related studies in this field—including recent, large-scale studies, have shown that health and behavioural outcomes are as good or better when nutritionally sound vegan diets are used. To safeguard health, it is important that pet guardians feed only commercial diets labeled as nutritionally complete, produced by reputable companies with good standards."<p>The article mostly argues that we should want dogs and cats to have vegan diets for environmental reasons, and suggests people should risk their pets' health for the sake of the environment.
