I have read that torts can be fed bananas (as a treat). Howevever my beloved Greek tortoise would not eat any. Last night I was eating...chocolate. A tiny bit of it fell into my tort's enclosure so I left it to see my tort's reaction. Surprisingly enough it ate it! Furthermore it began to move...
I wouldn't because of the sugar, even though theobromine may be metabolised, it seems it made one turtle who ate too much vomit. Inconclusive results,
I certainly wouldn't experiment on Tidgy.
