I wonder if all quadrupeds (or, mammals, at least), are edible?
From what I have collected, even down to fish, everything is edible apart from being sick or infected, and, apart from some glands secreting (deliberately, as far as this term makes sense in evolution) poisonous molecules.
This is (if correct), in stark contrast to plants, where frequently many parts of the plant contains poisons. (It has some logic: plants can't run away or mechanically fight back.)
Q: Are all quadrupeds edible?
An additional bonus on: WHY?
