Yes, tortoises can eat cabbage in small amounts, but it should only be offered occasionally. While cabbage contains some beneficial nutrients, it also contains compounds called goitrogens that can interfere with thyroid function if fed too frequently. Because of this, cabbage should not be a staple food in a tortoise’s diet. It should be mixed in with other staple type greens, here is a Tortoise & Turtle Feeding List to look at.

Can Tortoises Eat Cabbage?
Cabbage is generally safe for tortoises when offered in moderation. Many tortoises will happily eat cabbage because of its crunchy texture, mild flavor and I believe the brighter colors attract them.
However, cabbage should only be treated as an occasional vegetable rather than a primary food source. A healthy tortoise diet should mainly consist of fiber-rich leafy greens and weeds that more closely resemble what tortoises would eat in the wild. Higher fiber leafy greens with a balance of calcium and fiber are best.
Offering small pieces of cabbage occasionally can add variety to a tortoise’s diet, but it should never replace staple greens.
Nutritional Value of Cabbage
Cabage contains several nutrients that can be beneficial when fed in small amounts.
These can include:
• Vitamin C
• Vitamin K
• Fiber
• Antioxidants
Despite these nutrients found in cabbage, it is still not as nutritionally balanced as many other leafy greens commonly fed to tortoises. Because of this, cabbage is best mixed in with other healthier staple food rather than be fed on its own.

Why Cabbage Should Only Be Fed Occasionally
The main concern with cabbage is that it contains goitrogens.
Goitrogens are a compound that can interfere with the thyroid gland when consumed in large quantities over time. While small amounts of cabbage are generally harmless, feeding it too often could potential cause health problems. I rarely ever feed cabbage unless I had some given to me or left over from eating it myself.
To avoid over feeding cabbage, you should only be offered as a rare addition to a well balanced diet. If you you want to learn more about Toxic Foods for Tortoises this article is for you!
