i know u can feed them hearts and stuff, but i ask because the liver is a filter for toxins basically and wondered if it would be safe? I fed some as snacks to my turtles and only want to use them as treats and since they have a shelf date i wanted to see what your thoughts were on livers. this iwill not be a staple meal by any means, just as a treat now and again when the turtles get their treats. thanks a bunch!
