Its a jungle out there, rats typically dont spend that much time near the waters where they can run into danger, but if they do. lol. I always enjoy the oddities that arnt thought of as food for fish. Such as large Esox eating waterfowl. Either way, the rtc loved the mouse and with what he left me the next day, it digested quite well. He also grew quite abit that week(hes only 8" right now)
