My hermanns tortoise Dash really likes nettles but i think they are stinging him!! Today he had the strangest reaction to eating them. He jerked around, opened his beak really wide and moved his head from side to side as if they were stinging him. He just kept eating them but eventually i took them out of his enclosure because i just couldn't watch it anymore. Am i being paranoid or are they actually stinging him? And if so, what can i do to get rid of or at least lessen the stinging? I know nettles are good for them and he clearly likes them so I'm just wondering if there's a solution to this?
