Is It Possible (Or Safe) to Make Your Pet a Vegetarian?
Ever hear of the saying “You are what you eat”? I’m an omnivore (although I honor “Meatless Mondays”), but I’m fully supportive of you choosing to eat healthy – whether it’s as an omnivore, vegetarian, or vegan. That said, when it comes to your pet, I’m going to take the stance and say that you should never make your pet a vegetarian…especially for cats.
About 15 years ago, I treated a young, 15 month-old cat for a severe, rare type of heart disease called dilated cardiomyopathy (DCM) – thankfully, we hardly see this type of heart disease anymore in cats. This kitten had an extremely loud heart murmur (meaning the sound was abnormal when I listened with a stethoscope). The severity of the heart murmur was graded a 6/6 (with 1 being the softest and 6 being the worst). The cause of the heart murmur? Inappropriate diet. The cause of this kitten’s heart disease was the owner’s fault, as the owner made the kitten a vegetarian (forcing his dietary beliefs on his pet).
We don’t see this type of heart disease as much as we used to thanks to better nutrition. Veterinarians were able to link certain types of DCM to the lack of taurine, an essential amino acid (essential means that the body can’t make it, and it’s imperative that the diet contain it).
What should you learn from this? Don’t make your pet – especially your cat – a vegetarian.
While dogs are omnivores (they can eat both plant and animal sources of protein), cats are strict carnivores. While there are cat vegetarian and vegan diets commercially available, these are never recommended by veterinarians (well, at least the good ones).
Please don’t make your cat a vegetarian. If you want to cook for your cat (and can deal with having meat in your vegan refrigerator), then that’s OK, as long as you realize that it is very difficult to make a homemade, nutritionally balanced diet for your cat without screwing something up. If you want to attempt it, make sure it’s recommended by a board-certified veterinary nutritionist (that does not mean trying whatever you stumble upon on the Internet!), as it will require appropriate electrolyte, vitamin, and mineral supplementation (especially focusing on
