Most veterinarians strongly recommend against feeding cats a vegetarian diet. While vegetarian cat food can be supplemented and formulated to meet AAFCO standards, there is a paucity of scientific data regarding bioavailability of essential nutrients and long-term health effects. The bioavailability of synthetic taurine in these foods, for example, is unknown. However, the majority of commercial cat foods add synthetic taurine because the natural taurine is denatured during high-heat processing. So there is a huge sample of cats lacking any signs of deficiency during a lifetime of consuming and utilizing synthetic taurine. Still, the bioavailability of many supplemented nutrients remains unknown.
Anecdotally, the thousands or tens of thousands of cats currently on vegetarian diets are in adequate to excellent health.3 Continue reading

Despite warnings from veterinarians, some animal caregivers are choosing to feed their pets vegetarian food for ethical reasons. Aside from nutritional health concerns, some veterinarians think it is inhumane to the animal not to feed a ‘natural’ diet. So why do these caregivers feel that vegetarian diets for their carnivorous companion animals are actually more humane? Most are vegans or vegetarians themselves who believe in animal rights and do not wish to contribute to the suffering of farm animals. They are considering the overall consequences of providing a flesh-based diet, not simply the consequences for their companion animals alone. Continue reading
