Yes, Hermann’s tortoises can eat kale, but only as an occasional part of a mixed diet. Kale is high in oxalates and goitrogens, so it should not be the main green.
Why Kale Is a “Sometimes” Food
Kale has useful calcium and vitamin A, but it also contains oxalates, which bind to calcium and make it harder to absorb. In a tortoise that already struggles to get enough calcium or UVB light, a diet heavy in kale can add to the risk of shell and bone problems. Kale also contains compounds that can interfere with thyroid function when fed in large amounts.
How Much and How Often
- Offer kale no more than once a week, mixed into other greens.
- Keep it to a small handful chopped fine for an adult.
- Wash it well and remove any thick stems.
Better Everyday Greens
Hermann’s tortoises do best on a wide variety of weeds and leaves, such as:
- Dandelion leaves and flowers
- Plantain weed and clover
- Endive, escarole and radicchio
- Mulberry and hibiscus leaves
Our Hermann’s tortoise food list covers more, and the Eastern Hermann’s diet guide explains how the diet should look across the seasons.
Keep Calcium on Track
Dust food lightly with a calcium supplement a few times a week and make sure your tortoise has access to natural sunlight or a proper UVB lamp. See calcium-rich foods for tortoises for more.
Bottom Line
A little kale now and then is fine. Make dandelion, plantain and other weeds the base of the diet, and call a reptile vet if your tortoise loses appetite or shows shell changes.
