Vegan Cat Food Study Dodd et al. 2021 BMC Veterinary Research

Cats, being obligate carnivores, have unique dietary requirements for nutrients most commonly found in dietary ingredients of animal origin.

As such, feeding a diet devoid of animal-derived ingredients has been postulated as a possible cause of nutrient imbalances and adverse health outcomes.

🔬 At the outset, the researchers suspected that cats fed a plant-based diet would have a higher prevalence of negative health effects, such as

  • heart disease
  • dental disease
  • skin disease
  • hormone problems
  • stomach and liver problems
  • urinary problems
  • eyesight problems
  • kidney problems

However, contrary to the expectations, cat owners who participated in the study, perceived no body system or disorder to be at particular risk when feeding a plant-based diet to cats. 

This conclusion is based on the comparison of

667 cats fed a meat-based diet


187 cats fed a plant-based diet.

Detailed statics were obtained and now presented on the slides.

These results are possible only when cats are fed complete plant-based diets (i.e. diets containing the right amino-acids (Taurine), minerals, vitamins and fatty acids). When cats are fed vegetables only (without any supplementation) then cats become deficient in key nutrients.

Owners who fed their cats plant-based diets had a positive perception of their cats’ health, and reported a belief of better general health, better body condition, and fewer health disorders as compared to owners who fed their cats meat-based diets.

Further research is warranted to determine if these results are replicable in a prospective investigation.
