Didn't have any fighting when I had female ferrets. Been lucky. Have never had any fighting or slapping of any kind (at least not to/from/among the ferrets). I DID notice females seem to be smarter...or more curious...or more willing and able to get into unauthorized areas. More active. Got some stories there.... Have three ferrets now, all males. Tiny little Ehrich is in his prime but weighs barely 1 pound and is smaller than most females I've seen. He looks and acts like a female. He even has that little pointy female head structure (hermophrodite?.....just a thought...he is greatly loved). Ehrich is into Everything!!! Non-stop! I think small size has something to contribute to extra activity. I have also noticed ferrets with white feet "silver mitts" are more hyper. Anyone else see that? God help the person who is owned by a Tiny, White-footed, Female Ferret! Been there. I very sadly and surely still miss Marie and her love. The unending challenges and excitement she brought me. Rainbow Bridge has been hopping and climbing and dancing and getting into stuff...faster and farther, for the past 3 years. God Bless All Ferrets, especially my Marie and my little *#&$ Ehrich!
