That is disgusting. I would never buy that product again. It would be supporting a company that obviously does not take care of its rats in a humane and CLEAN way. Who knows what else is wrong internally with those feeders.

Meaning, DO NOT FEED THEM TO YOUR SNAKES. And RETURN them to the store you got them from and COMPLAIN. Also, call that company and COMPLAIN. Take photos. That is absolutely FILTHY.
