Yes, Russian tortoises can eat bok choy in moderation. It is one of the better cultivated greens because it is relatively high in calcium and low in oxalates, but it should not replace weeds and grasses.
Why Bok Choy Works
Bok choy (Chinese cabbage) is a leafy brassica with a good calcium-to-phosphorus balance and plenty of water. Compared with spinach or beet greens, it binds less calcium, so it is a reasonable addition to a rotation of greens.
The Catch
Like other cabbage-family plants, bok choy contains goitrogens that can affect the thyroid when fed in large amounts. Variety is the safeguard.
How Much to Feed
- Offer chopped leaves once or twice a week, mixed with other greens.
- Wash the leaves, and use the leafy parts more than the thick white stems.
- Do not make it more than a quarter of any meal.
Build the Rest of the Diet Around Weeds
Russian tortoises are grazers from dry, scrubby country. Their staples should be dandelion, plantain, clover, safe lawn grass and other broadleaf weeds. Read our Horsefield tortoise tomato guide and favorite foods of tortoises for more ideas.
Bottom Line
Bok choy is a good occasional green. Keep a variety of weeds and fibrous leaves as the base, supply UVB light and calcium, and call a reptile vet if you notice appetite loss or shell changes.
