Yes, tortoises can eat thistle. Thistle is a wild plant that many grazing tortoise species can safely consume when it is collected from pesticide-free areas. While the plant may look prickly, many tortoises will still eat the leaves and softer parts of the plant.
When fed as part of a varied diet, thistle can provide fiber and nutrients that support healthy digestion. For a complete diet guide, check out What Do Tortoises Eat
Is Thistle Safe for Tortoises?
Thistle is generally considered safe for tortoises when fed in moderation. Many species such as Russian tortoises, sulcata tortoises, Hermann’s tortoises, and leopard tortoises may naturally encounter and eat thistle while grazing outdoors.
However, like all foods, it should be offered alongside a variety of other greens and weeds to ensure balanced nutrition. These foods provide better fiber and calcium balance. I made this quick Tortoise Food Chart for Beginners if you want to bookmark it.
