Can Russian Tortoises eat Watermelon?
Citrullus lanatus
Safety verdict
Caution
Why
Very high water content combined with sugar makes it a poor dietary choice. Diarrhea risk if fed regularly; fine as a very occasional hydration boost in hot weather.
How much / how often
Very rare treat — a small piece once per month, if at all. Not a substitute for a water dish.
