well i am very inspired of u taking in those animals i did the same with some ferrets and man i loved them to death and i made sure they had good homes because i jus didnt have the room for them and it made me cry for weeks cuz i felt so bad but i kno they are in good hands......i had the same problem with my female pit her and her sister would constantly get into it and they would fight to the death and there was nothing that we could do to prevent it so we had to move away from her sister and she does real good now but she cant be by other females her size...i was told that it was a dominance issue....but im glad that u have made them see it ur way and tell them to b nice it is always good to have a buddy by ur side especially wen it is blood.
