fighting, what do I do? Do I seperate them? they were born together i believe and i dont know what they would be thinking in their tiny minds when they are seperated and they would never be aloowed to see each other again. they are both males and they are black bear hamsters. they make loud squeaking noises and they stand up on two legs an dstart to pound each other, whenever they spot me staring at them they stop, it has started to get pretty bad today and i am concerned that they could be hurt since they always stay away and rarely move compared to when they used to. I got the first one on its own and then two weeks later i decided to buy the other one and they seemed perfect together. i was extremely concerened recently today because i braught them a snap on wheel which hangs on the outside of the cage and one of them always goes on it, and then i heard squeaking and they were both in there fighting and i couldnt get them out, so i had to wait for them and see if they would stop the violence, please help..
