I think Bob's concern (well... at least it's mine, if not Bob's, but I know Bob and I have talked about it) is mainly the shortening of the snout, which can and does impact the jaws and teeth and, possibly, eyes and brain, as well as changing how large or small ferrets are on a human whim. The cats and dogs that have been bred to have "flat" faces tend to have many eye problems due to that flattening of the face/snout. The other concern is making the skeleton too large or to small to actually handle the weight of the body (think of hip dysplasia in large dogs). Since these are not widespread among ferrets (or do not exist at all), it would be best to learn from the errors of dog and cat breeders who went too far and harmed the animal while trying to breed them to their own purposes. I think your point is that skeletal changes obviously do occur in domesticated animals vis-a-vis their wild ancestors. Yes -- and Bob has pointed out (in past posts) that there are changes in the skulls of ferrets and other domesticated animals. The caveat is to beware of changing these structures further than the domestication process "naturally" changes them (how's that for an oxymoron?). Cats and dogs that cannot sustain themselves without constant human intervention (tear-duct irrigation etc.) or cattle that are created that they can't support their own weight are IMO an abomination: the fruit of human-unkind's arrogance. These are living creatures and we made them dependent upon us; we are responsible for doing right by the dependence that we created. If we have the opportunity to prevent such problems in ferrets -- and we do -- and we are aware that our actions can create these problems -- and we are -- we have an obligation to do what's best and right for the animals and prevent the problems. When dogs and cats and many other animals were being domesticated, we humans didn't have the knowledge we have today. What does it make us if we ignore that knowledge to the detriment of ferrets? --Mary & the Fuzz ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ Mary R.
