Vegan Pet Food Digestibility Review Shows High Nutrient Absorption
A scientific review published in the journal *Animals* examined 31 studies on the digestibility of vegan, vegetarian and plant‑based pet diets for dogs and cats. The analysis covered 22 studies on dogs, two on cats and seven that included both species. Across diverse study designs and ingredients—including wheat gluten, rice protein, soy‑derived proteins, peas, lentils, chickpeas, potato protein, quinoa and microbially‑fermented proteins—the review found that these diets are generally well digested and not significantly less digestible than conventional meat‑based foods. Some of the studies also evaluated commercially available vegan dog foods containing peas, barley, oats, sunflower oil and lentils, reporting similarly high digestibility.
The review’s lead author, Andrew Knight, an adjunct professor at Murdoch University’s veterinary school in Australia, said the findings challenge the perception that dogs and cats cannot effectively process plant‑based proteins. He noted that the global vegan and plant‑based pet food market was valued at USD 26.9 billion in 2024 and is projected to grow at an annual rate of 7.8%, driven by rising interest in pet health, environmental sustainability and animal welfare.
