First - ya gotta define 'edible'... In some circles, only thing that may not digest well is the horns and hooves.. I.e., good way to 'bust' a hunter who leaves the entrails on the ground - much of those can be considered 'edible'..
Edible could include the hooves... ever heard of 'pigfoot tea'!
Figure 'deerfoot tea' would be about the same.
