Sukie can correct me if I am wrong, but I think there is some misunderstanding of what she wrote: >From: Sukie Crandall <[log in to unmask]> >Past selective pressures DO narrow what is best under natural >conditions for a species IN YOUTH AND IN REPRODUCTIVE YEARS, but once >a ferret is beyond normal reproductive years there is not a natural >selection situation which defines what is healthiest. I interpreted this to mean that a wild animal eats a diet that is optimal for having the greatest number of offspring during its prime reproductive years, which is not necessarily a diet that is optimal for longevity, since evolutionary pressure is concerned much less with how long an individual lives and far more with how many individuals there are. A very high fat diet, to make up a random example, might be very nourishing during the reproductive years and cause heart attacks as an animal ages--that diet won't be selected against, because the offspring have already been produced before the end effect of that diet is felt by the individual, and thus there is no pressure to move away from that diet. I have no strong opinion one way or the other about raw diet, etc--in a perfect world, I would feed raw/slightly cooked, but in this imperfect world I feed Innova Evo Ferret kibble, which is the best compromise I can arrive at for the lives of all those in my household. I just used to be an Evolution 101 teaching assistant and hoped to provide some clarification :) Regina "Is that my business? Well, what is my business? Do I know? Did I ever know?
