Dogs and cats are among the most resilient animals on the planet. They are able to withstand really significant nutritional abuse, in my opinion, without dying. Degeneration does occur as the result of an inappropriate diet, but sudden death does not.

So one of the reasons we’ve been able to deceive ourselves into believing convenience pet foods are good for dogs and cats is because they don’t die immediately of acute starvation. For a hundred years our pets have been fed inappropriate diets that have kept them alive, but far from thriving like their wild relatives. Instead, we’ve created dozens of generations of nutritionally weakened animals that suffer from degenerative diseases linked to nutritional deficiencies.

So in a nutshell, for 99.99 percent of their time on earth, dogs and cats have consumed a natural diet. For .01 percent of the time, they have consumed an extruded, processed diet. Dogs and cats evolved to consume a low-carbohydrate diet. But for the last century, the majority of pet owners have fed pets a high-carbohydrate, low-moisture diet."
