Re: Should domesticated animals lost in a blizzaed be shuffled back into the appropriate draw deck?
They should go into the appropriate draw deck. This simulates that they are not extinct. Edit: Kyrill points out that it is already in the rules that such creatures are discarded, not kept in the draw deck. My bad.
In general an animal is less likely to go extinct once domesticated. Mankind has saved many a creature from extinction through domestication, such as cattle, hamsters, gingkoes, horses, camels, and possibly cheetahs and Indian elephants.
