Can My Cat Be A Vegetarian?

This might seem like a silly question to some, but the idea behind the question is worth exploring. You may have seen people claim that when they feed their cats a vegetarian diet, all sorts of wonderful health benefits follow. After all, if cutting out meat can make humans healthier, why not cats? Now there are some plants are good for cats, like broccoli, carrots, and pumpkins. And I’m not going to tell you to never feed your cat a vegetable, but I will tell you that feeding only plant-based foods will cause far more harm than good.

“So what kind of diet should a cat eat?”

Cats are obligate carnivores, which means their bodies are biologically designed to thrive on a diet that's primarily made up of animal-based protein. Unlike humans, who are omnivores and can survive on a diet that includes both plant and animal-based foods, cats require specific nutrients that are only found in animal-based sources. According to The Blue Cross, “...cats require a much higher level of protein than dogs and humans, and their ability to digest and use carbohydrates is much lower.” Different species have different nutritional needs, and the bones, organs, and blood in meat contain these micro-nutrients that cats need to live.

“What kind of nutrients?”

One of the big nutrients cats require is the amino acid Taurine. Taurine is essential for cats' cardiovascular health, vision, and immune systems. Taurine is only naturally found in meat, fish, and other animal-based proteins, but not in plant-based foods. Without enough taurine in their diet, cats can develop serious health problems like heart disease, feline central retinal degeneration (FCRD), or even die.

Another nutrient that's essential for cats is arachidonic acid, which is an omega-6 fatty acid found in animal protein. Arachidonic acid is vital for their growth, reproductive health, and immune system. Without enough of it, cats can develop skin and coat problems, digestive issues, and even liver damage.

Lastly, cats require vitamin B12, which is essential for their nervous system, red blood cell formation, and overall health. Vitamin B12 is found almost exclusively in animal-based proteins, and without it, cats can develop anemia, lethargy, and other health complications.

Each of these vital nutrients cannot be found in plant based foods, and your cat will suffer without them.

Many people choose to follow vegetarian or vegan diets out of compassion and respect for animals, which is truly admirable. At the same time, it is important to recognize that cats have unique nutritional needs that differ from humans, and providing them with a balanced diet suited to their biology is essential for their well-being. While some may find it challenging to feed their pet’s meat, ensuring that cats receive ethically sourced meat can be a thoughtful way to honor both your values and your pet’s health.
