Is There Such a Thing as a Vegetarian Snake?

If you love reptiles but are squeamish about feeding mice, rats, or other prey animals, you might be wondering if there is a snake out there that eats vegetables instead. It is a reasonable question, especially as more people become interested in keeping snakes as pets. Unfortunately, the answer is pretty straightforward, and it is not the one most people are hoping for.

There is no such thing as a vegetarian snake. Every single species of snake on the planet is a carnivore, meaning they eat other animals exclusively. No snake eats plants, fruits, vegetables, or any other non animal food source. This is not a matter of preference or training. It is a fundamental part of their biology that cannot be changed.

Why Snakes Cannot Be Vegetarian

Snakes are obligate carnivores, which means their bodies are designed specifically to digest and process animal protein. Their digestive systems lack the enzymes needed to break down plant matter. Even if a snake somehow swallowed a piece of fruit or vegetable, its body would not be able to extract any nutrition from it.

Their entire anatomy is built for eating animals. Snakes have backward facing teeth designed to grip prey, flexible jaws that can stretch to swallow animals larger than their own head, and a digestive system that can dissolve bones, fur, and feathers. None of these features would serve any purpose for eating plants. Evolution shaped snakes into efficient predators over millions of years, and there is simply no vegetarian branch on the snake family tree.

What Do Different Snakes Eat?

While all snakes eat animals, the specific diet varies quite a bit depending on the species. Most popular pet snakes eat rodents like mice and rats. Ball pythons, corn snakes, and king snakes all thrive on a diet of appropriately sized rodents, which are readily available frozen from pet stores and reptile suppliers.

Some snakes specialize in other types of prey. Garter snakes eat fish, worms, and amphibians. Egg eating snakes feed exclusively on bird eggs. King cobras eat other snakes. Green tree pythons eat birds and small mammals. In the wild, the variety of snake diets is remarkable, but every single one of those diets consists entirely of animal based food.

Options for Squeamish Snake Owners

If the idea of feeding rodents to a snake bothers you, there are a few ways to make it more manageable. The most common approach is feeding frozen and thawed prey instead of live animals. Frozen mice and rats can be purchased in bulk, stored in the freezer, and thawed as needed. Most snake keepers find that handling a frozen, thawed mouse is much less distressing than dealing with live prey. It is also safer for the snake, since live rodents can actually bite and injure snakes during feeding.

Another option is to consider a snake species that eats something other than rodents. Egg eating snakes are a great example. African egg eating snakes feed exclusively on small bird eggs, which many people find much less disturbing to handle than rodents. Garter snakes can be fed a diet of fish and worms, which is another option that some people find easier to deal with.

Can You Force a Snake to Eat Plants?

No, and attempting to do so would be harmful and potentially fatal to the snake. Forcing a vegetarian or vegan diet on a snake is a form of animal cruelty because it goes directly against the animal’s biological needs. A snake fed only plant matter would slowly starve to death even with a full stomach, because its body simply cannot process plant material into usable nutrition.

If you are not comfortable with the realities of feeding a carnivorous pet, a snake may not be the right animal for you. There are plenty of wonderful herbivorous reptiles that make great pets, including iguanas, uromastyx lizards, and tortoises. These animals thrive on diets of leafy greens, vegetables, and fruits, and they can be just as interesting and rewarding to keep as snakes.

The Bottom Line

Snakes are carnivores without exception. There are no vegetarian snake species, and you cannot train or convert a snake to eat plants. If you want to keep a snake, you need to be prepared to feed it an appropriate animal based diet. If that is something you cannot do, consider one of the many herbivorous reptile species that would make a great alternative pet.
