I have recently been finding out more about Ferrets and have fallen in love with them!

I have been to the All Shires Ferret club where i met owners and the ferrets, and have done lots of research.

I can't get them yet, but I was basically just seeing if this set up would be suitable.

I wanted and polecat-colouredhob and a champagne point jill.
I was thinking, because of the smell of hobs and the whole season thing with the jills, to get them both neutured/spayed.
They would live in a whole garden shed, with levels, and tubes and hanging stuff/hammocks.
I'd get their distemper vaccine so that I could walk them.
They'd be fed Supreme Science Ferret food.

A few questions - would the above set-up be suitable?
I have heard that kits wouldn't be suitable for first time owners due to the nipping...is this true? I also heard that they can come 'nip-trained!'
Do they take well to walking?
Do they smell REALLy bad or just kind of musty? The one's i've held varied to be honest...

I'msure i'll think of a hundred more questions!
thanks
