Turtles are unique pets that require special care when it comes to their diet. As pet owners, we want to make sure we are providing them with foods that are safe and healthy. A common question that arises is whether turtles can eat cheese.
If you’re short on time, here’s a quick answer to your question: Most experts agree that cheese should be avoided for turtles. While small amounts may not cause immediate harm, cheese provides little nutritional value for turtles and can lead to digestive issues or weight gain if fed regularly.
In this comprehensive article, we’ll explore whether or not turtles can eat cheese in further detail. We’ll look at the nutritional makeup of cheese, potential health impacts for turtles, safer cheese alternatives, and best practices for feeding your turtle.
The Nutritional Composition of Cheese
High in fat and calcium
Cheese is an energy-dense food that is high in fat and calcium content. An ounce (28 grams) of cheddar cheese contains about 110-130 calories and 9-10 grams of fat, of which around 6 grams are saturated fat.
The high calorie and fat content comes from the milk fat and milk solids used to produce cheese.
On the positive side, cheese is one of the richest natural sources of calcium. Calcium is vital for healthy bones, muscle and nerve function. The same ounce portion of cheddar cheese packs over 200 mg of calcium, meeting over 20% of the daily calcium needs for adults.
Low in essential vitamins and minerals
While cheese is high in calories and calcium, it lacks vital micronutrients like vitamins A, C, D and B vitamins compared to fruits and vegetables. It also does not contain high levels of essential minerals like potassium, magnesium and iron.
This makes cheese more of an energy-booster rather than a source of vitamins and minerals. Relying too much on cheese could lead to vitamin and mineral deficiencies over time if care is not taken to eat a balanced diet.
Lactose and casein content
Cheese also contains lactose, though aged hard cheeses contain negligible amounts as the lactose converts to lactic acid during aging. Lactose intolerance is common in turtles, so cheese should be avoided.
Additionally, cheese is very high in casein and caseinates, milk proteins that are difficult for turtles to digest properly. The hard cheese curds could also pose a choking hazard for turtles.
Potential Health Risks of Feeding Cheese to Turtles
Feeding cheese or other dairy products to pet turtles may seem harmless, but it can actually pose some serious health issues. Let’s take a closer look at some of the potential risks.
Weight Gain
Cheese is very high in fat and calories compared to a turtle’s normal diet. Too much cheese can quickly lead to obesity and other weight-related problems in turtles if fed on a regular basis.
GI and Digestive Issues
Turtles are lactose intolerant and lack the enzymes needed to properly digest dairy. Feeding cheese or other dairy can cause gastrointestinal issues like diarrhea, vomiting, dehydration, nutritional deficiencies, and more.
Respiratory Infections
The warm, moist environment produced by dairy in a turtle’s enclosure can promote the growth of mold, fungi, and bacteria. This can lead to potentially fatal respiratory and shell infections in turtles if not caught and treated early.
Nutritional Imbalances
Cheese and dairy products lack the proper vitamins, minerals, and nutrients turtles need. Relying too heavily on cheese rather than a balanced commercial pellet diet can lead to metabolic bone disease, organ failure, and other serious health conditions over time.
While the occasional small scrap of cheese as a rare treat is likely ok, regular or excessive feeding can be quite problematic for a turtle’s health and wellbeing. It’s best to stick to a healthy, vegetable-focused diet according to your particular turtle species’ needs.

Healthier Alternatives to Cheese for Turtles
Mealworms and Crickets
Mealworms and crickets are great protein sources for turtles as an alternative to cheese. Both are soft-bodied insects that are easy for turtles to digest. Mealworms contain about 20% protein, while crickets contain around 13% protein.
The protein in insects is highly bioavailable, meaning turtles can efficiently absorb and utilize it. Mealworms and crickets also provide important vitamins and minerals like vitamin B12, calcium, and zinc.
Just be sure to gut load your insects with nutritious foods before feeding them to your turtle.
Vegetables and Fruits
Offering veggies and fruits is another healthy way to provide balanced nutrition for turtles without cheese. Some great options include:
- Leafy greens – kale, lettuce, spinach
- Other veggies – zucchini, bell peppers, carrots
- Fruits – melons, berries, bananas
Veggies and fruits give turtles important vitamins, minerals, and antioxidants. They also provide dietary fiber to support digestive health. Aim to feed your turtle 1-2 teaspoons of produce 2-3 times per week. Be sure to chop produce into bite-sized pieces.
Shellfish and Fish
For aquatic turtles, shellfish and fish make excellent additions to their diet in place of cheese. Shrimp, clams, mussels, and oysters provide protein along with omega-3 fatty acids. Lean fish like tilapia, salmon, and trout also offer great nutrition. Offer small pieces of seafood 1-2 times per week.
Shellfish and fish provide beneficial nutrients not found in cheese, supporting immune function, brain development, and overall health in turtles.
Commercial Turtle Pellets and Treats
High-quality commercial diets for turtles, like pellets and treats, are formulated to meet all of their nutritional needs without cheese. Look for options that contain:
- 25-35% protein
- 2-3% fat
- 1-1.5% calcium
- 1-1.5% phosphorus
Reptomin and Mazuri are reputable brands when selecting commercial foods. Use pellets as a turtle’s staple food, supplemented with treats like Zoo Med’s Natural Aquatic Turtle Food. Commercial diets give balanced nutrition in an easy, convenient form.
Best Practices When Feeding Your Turtle
Offer a varied diet
Turtles are omnivores and need a balanced diet consisting of protein, fruits, vegetables, and calcium-rich foods. A good turtle diet should include:
- Proteins like worms, small feeder fish, shrimp, lean meat, egg yolks
- Leafy greens like kale, lettuce, spinach
- Vegetables like zucchini, squash, bell peppers
- Some fruits like berries and melon
- Only feed an amount they can consume within 5-10 minutes 1-2 times per day.
- Remove any uneaten food to prevent the water from fouling.
- For juveniles, feed daily. For adults, feed every other day or 2-3 times per week.
- Fast your turtle 1 day a week to allow its digestive system to rest.
Avoid feeding your turtle the same foods day after day. Provide variety and rotate through different proteins, veggies, and fruits to give them diverse nutrients. An excellent diet will support their health, growth, and activity levels.
Avoid overfeeding
It’s easy to overfeed a turtle, especially since most species are opportunistic eaters. But overfeeding can lead to obesity, nutritional deficiencies, and other health issues. Here are some tips:
Pay attention to your turtle’s body condition and energy levels. Adjust portions as needed to maintain a healthy weight.
Supplement with calcium and vitamins
Turtles need extra calcium and vitamins, especially vitamin D3. A calcium deficiency can cause their shells to become soft. Purchase calcium and vitamin supplements formulated specifically for reptiles. Lightly dust foods with supplements 1-2 times per week.
UVB lighting also helps turtles produce vitamin D3 naturally.
Provide clean, fresh water
Clean water is vital for hydration and health. Change your turtle’s water daily, using dechlorinated water without soap residues. The water should be dechlorinated by letting it sit 24 hours before use or using water conditioner. The ideal water temperature is around 75-80°F.
Having both a basking dock and deeper swimming area allows temperature regulation.
Monitor their health
Watch for any signs of illness and distress, such as changes in eating, basking, swimming habits. Look for discharge from eyes/nose, shell abnormalities, lethargy, or weight changes. Take your turtle to an exotic vet for a wellness check 1-2 times per year.
Proper nutrition, housing, light, and care will help keep your turtle healthy and happy!
Conclusion
To summarize, most veterinarians and turtle experts recommend against offering cheese to turtles. While an occasional small amount may not cause immediate harm, cheese provides minimal nutritional value and risks weight gain or other health issues.
There are far better food options to provide your turtle with a balanced, nutritious diet.
When in doubt, stick to a varied diet of vegetables, quality proteins, turtle pellets, and supplements as needed. Avoid unhealthy treats like cheese. With proper nutrition and care, your turtle can live a long and happy life as a healthy pet.
