Hi. I have two tortoises. One male and one female. The female always starts biting the male's nails. She wasn't doing it earlier but now everytime she goes near him, she smells his nails and tries eating it. We have stopped her many a times but one time she literally bit his nail, pulled it out and "ate" his nail! Seriously? She removed the nail like she was eating a snack and ate it. And now she is trying to do the same with other nails of his too. I'm scared . Please any one knows the reason?
