Can my cat live on a vegetarian diet?

Sadly, no. Cats are what are considered obligate carnivores, meaning that they need to have a meat-based diet. That's different from dogs that are considered omnivorous, so they have a lot more variety in their diet. Cats need to eat a primarily meat-based diet. That being said, we also need to keep in mind that it needs to be a balanced diet, so just throwing some meat chunks at your cat every day is not going to work out. And we'll talk about that more later, but we want to look for a meat-based diet balanced by a veterinary nutritionist and comes from high-quality commercial pet food.

We don’t recommend that your cat lives solely on a vegetarian diet. Compared to dogs, cats are the more carnivorous species of the two, whereas dogs still need protein. These guys need it a bit more strongly, so I wouldn't recommend a vegetarian or vegan diet for cats.

Nope. Cats can not eat vegetarian diets. Some scavengers would, but cats have to have meat because they are obligate carnivores. They cannot produce essential amino acids that are important for their heart and other health. They have to get it from meat. It's unfortunate for some people, but that is a reality.

That would be a no. They cannot. Cats have a very high demand for protein. Let's think about the hierarchy of animals in the animal kingdom. The one animal, at least that I know of, that has the highest demand for protein is cats. Big cats, little cats, all cats in between. Dogs also have a higher demand, but not as much of high demand for protein as cats. We're lower on the spectrum. We can have a little bit more of a blended diet. But cats cannot sustain long term on a vegetarian diet because of the lack of protein they'll get.

No, cats should not be fed a vegetarian diet. In fact, if they are fed a vegetarian diet over a period of time, they will actually die. They are obligated to eat protein, as they are carnivores.
