Hi I use quite a lot of cat treats as I have both cats and ferrets and none of my ferrets have come to any harm, with one ferret now in her 14th year they can not be that bad. http://www.geocities.com/houseferrets13uk/tony-pet.html Most of my ferrets have been seen on UK National Television http://www.bbc.co.uk/nature/environment/programmes/countryfile/ [Posted in FML issue 4391]
