My female is Isabella and she is 3 lbs, my male is Eddie and he is 4 lbs. They are both bosses to Axel and Isabella thinks she is the boss of EVERYTHING!! They are funny. Axel is still learning to be easy with them because they are so small. He sometimes gets too excited and wants to jump and rough house with them. Them usually growl and give him a warning nip and he backs off (for 3 seconds.. lol). Throw in my 20 month old and we have a zoo.
