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.
