Is there such a thing? (Other than the wild ones of course.) We let our ferret out every once in a while and don't worry about him because he always comes running when we squeak his squeaky toy. We live in the mountains & don't have much in the way of neighbors to confuse him and he always stays near the house. We've been opening a window for the cats to get out and poor sammy will stand on the sill thinking "hmm, this is too far to jump, isn't it?" Has anyone considered or used a cat door for ferrets before? - shawn [Posted in FML issue 1557]
