You need to get your ferret to a vet asap. It is likely that the new
ferret brought some bug in with him. In any event, Hurley has something
which is causing him to not be able to properly digest food.
It's a good sign that he's peeing, but you should still check for
dehydration.
Not eating is a bad sign, and they can go downhill very quickly. With
the right care, they can bounce back just as fast, which is why it's
critical to get him that help.
