Hello, My name is Joanne and I have 3 female ferrets. Natasha, Sasha and Snowflake. Snowflake is Albino. They are all about 3 years old. In comes a 4th male at 8 weeks old. Shadow, is kept in his own cage in a different room. Slowly introducing him to the others. I let shadow out in his room and did know snowflake was in there. I heard shadow screaming and snowflake was a?ttacking the little guy and biting him very hard. He is ok. I wonder if this is going to work out. Do I need to keep them separated until Shadow is fully grown? Will shadow ever be safe if I intergrate them eventually? How long before the kit is fully grown? feeling like a bad mommy
