I have always wanted to get a ferret for a pet They are the domesticated form of the European polecat.
They are pretty popular as pets, so they must adapt fairly well to humans and domestication
Yes, they usually have brown, black, white, and mixed fur. I would probably want a white one.
Some parts of the world have restrictions on keeping them, especially New Zealand. They have some feral ones there.
Wow, I didn't know that. They normally live between 7 and 10 years. Males are larger than the females.
And they are small too. I think they go about one and a half up to four pounds . 
Yes, that is true. The name "ferret" derives from "furittus", which means "little thief". Ferrets are notorious for secreting small items.
They have up to three litters a year, so you would have to be careful about that too.
I first read about ferrets in Brian Jacques' "Redwall" novels where ferrets are usually villainous.
Haven't heard of it. They like to be active at dawn and dusk , so that might be a problem sometimes.
