They war danced?  I know they have been domesticated for thousands of years, what is their dance like?
I used to own ferrets. Man I miss having them. Aw sorry to hear it.  Did you know that the word ferret comes from a Latin word meaning little thief?   Apparently ferrets like secreting away small things. THey sure our little theives they always hide stuff under the furniture. Oh really!  Apparently they can have white, black, brown or mixed fur.  What color were yours? Mine were the typical brown ferret color. I loved it when they war danced.
The history of the ferret's domestication is uncertain, like that of most other domestic animals, but it is likely that ferrets have been domesticated for at least 2,500 years.
