http://www.ferretstore.com/h-415.html and http://www.ferretstore.com/tf-01140.html are the best foods around. Although these are more expensive than catfood it's really better for your ferret. When given quality food the ferret will also eat less.

Also get some ferretone: they really love that shit and they simply love it.

Be prepared to get bitten a few times in the beginning, but he/she will become the perfect pet if threatend well.
