The eastern box turtle ( Terrapene carolina carolina) is a captivating reptile known for its domed shell and distinctive markings. Proper nutrition is crucial for the health and longevity of these turtles, which can live for several decades. This article provides a detailed guide to understanding and meeting the dietary needs of eastern box turtles, covering everything from essential nutrients to practical feeding strategies.
Understanding the Dietary Needs of Eastern Box Turtles
Eastern box turtles are omnivores, meaning they consume both plant and animal matter. In the wild, their diet consists of a wide variety of items, including insects, fruits, mushrooms, and even carrion. Replicating this diversity in captivity is key to ensuring optimal health. Younger box turtles tend to be more carnivorous, requiring a higher protein intake to support their rapid growth. As they mature, their diet shifts towards a more balanced mix of plant and animal matter.
The Ideal Diet Composition
A well-balanced diet for an adult eastern box turtle should consist of approximately:
- 50% Healthy Protein: This includes sources like earthworms, grubs, june bugs, snails, pillbugs, and fish.
- 40% Vegetables and Greens: A mix of dandelion, collard, turnip greens, hibiscus or dandelion flowers, and other suitable vegetables.
- 10% Fruits: Healthy, lower-sugar fruits like figs, raspberries, mulberries, apples, grapes, and melon.
Protein Sources: Meeting the Animal Matter Requirement
Providing sufficient protein can be a challenge, especially if your turtle is a picky eater. Here are some strategies and options:
- Live Foods: While some turtles readily accept live insects, others may be more hesitant. Persistence is key.
- Mixing Protein with Greens: Finely chop protein sources and mix them thoroughly with vegetables and greens to encourage consumption.
- Canned Options: Canned venison or whitefish can be a good alternative if your turtle refuses live protein.
- "Turtle Bananawich": For turtles with a sweet tooth, try stuffing a banana slice with pieces of nightcrawler and soaked, high-protein pellets. Sprinkle with Reptivite with D3.
- Gut-Loading Insects: If your turtle eats insects, "gut-load" them by feeding them nutritious fruits and vegetables for at least 48 hours before offering them to your turtle. This ensures that the insects themselves provide additional nutrients.
- Pre-killed options: Chicks, mice and quail chicks are also good options.
Vegetables and Greens: Providing Essential Nutrients
A variety of vegetables and greens should form a significant portion of the eastern box turtle's diet. Good options include:

- Turnip greens
- Hibiscus flowers
- Other suitable vegetables
Fruits: A Treat in Moderation
Fruits should be offered sparingly due to their sugar content. Opt for lower-sugar varieties such as:
- Figs
- Raspberries
- Mulberries
- Apples
- Grapes
- Melon
Avoid offering bananas too frequently, as their high potassium content can interfere with calcium absorption.
Addressing Picky Eating Habits
Eastern box turtles can be notoriously picky eaters, especially if they have been fed an improper diet in the past. Here are some tips for encouraging a varied diet:
- Persistence: Keep offering a variety of foods, even if your turtle initially refuses them.
- Mixing and Matching: Combine preferred foods with new or less appealing options.
- Food Processor: Use a food processor to create a finely chopped mix of greens, vegetables, and fruits.
- Color Preferences: Experiment with different colored foods, as turtles often have color preferences. Red options include apples, raspberries, and cabbage.
- Scent Enrichment: Add small amounts of banana to entice picky eaters.
Commercial Diets: A Supplement, Not a Substitute
While a varied diet of fresh foods is ideal, commercial diets can be a useful supplement. Mazuri is a well-regarded brand, with options like the Mazuri Tortoise Diet, aquatic turtle diet, and omnivore diet. Sandy Barnett, a box turtle expert, recommends Turtle Brittle. If using commercial diets, moisten them before mixing them with other foods.
Supplementation
To ensure your turtle receives all the necessary nutrients, consider the following supplements:

- Repashy Superveggie: Sprinkle this supplement powder on food to provide essential vitamins and minerals.
- Cuttlebone: Provide a cuttlebone as a source of calcium and to help keep your turtle's beak trimmed.
- Carotenoid Supplement: Use a carotenoid supplement like Repashy Superpig to enhance your turtle's natural coloration.
Water
Always provide access to clean drinking water. Eastern box turtles often soak in their water dish, so it's essential to clean and replace the water daily. A large flower pot saucer sunk into the substrate makes a good water dish.
Sample Feeding Schedule
- Young Turtles: Feed as much as they can eat daily.
- Adult Turtles: Feed every other day to prevent obesity.
Additional Tips for Success
- Environmental Factors: Ensure proper UVB lighting and humidity levels to stimulate appetite and overall health.
- Soaking: Soak your turtle in warm water daily for 10-15 minutes to help with hydration and appetite stimulation.
- Veterinary Consultation: If your turtle continues to have eating problems, consult a veterinarian experienced in reptile care.
- Enrichment: Provide a stimulating environment with plenty of hiding places, climbing opportunities, and edible plants.
- Mash: Make a turtle mash. Finely chop steamed sweet potato, cooked lean ground turkey, raw mushrooms, shredded carrot, raw corn, red leaf lettuce, raspberries, blueberries, and blackberries. Everything gets very finely chopped, and the turkey has to be drained and pressed.
