Can Russian Tortoises eat Spinach?
Spinacia oleracea
Safety verdict
Caution
Why
Very high oxalate content (~970 mg/100 g) binds dietary calcium in the gut, preventing absorption. Regular feeding risks calcium deficiency and MBD even if calcium is supplemented.
How much / how often
Very rarely — once per month maximum, small amounts. Not recommended as a regular food.
