So I've had my ferret Chris for almost a year now. He's three years old and and I recently got a new ferret that's a baby male about 6 months old (Jeff). I'm scared because I can't tell if they like each other or not.
Jeff is a very active hyper ferret, he often bites at peoples feet and likes to play rough. Chris is the older one and he is much more mellow. At first when I got them, they were fine together. Jeff would try to play with Chris but he would ignore him. But recently they get into fights - some were small and some bad and resulted in Jeff pooping himself.
Neither of them has ever bled, but it looks vicious to me. My cage has the ability to be split into two cages and when they were friendly I had them together and they would sleep together and be friendly. They would occasionally get into fights outside of the cage. After they started fighting out of the cage and Jeff started pooping himself, I made the cage into two cages. They both seemed fine and still are in separate cages but when they get out they sometimes still get into fights. When they get into fights or whatever it is, it starts off as them just smelling each other and then one gets all riled up and it always ends in Chris getting Jeff by the throat and Jeff will start loudly squeaking and I break it up. I need help I don't know what to do, whether this is normal and they're just playing around or if they genuinely don't like each other and I should just let them out separately.
