“I agree. Why burn perfectly good food”
Not very good eating... they are loaded with parasites.
... and not particularly nutritious - If one is ever stuck in the woods and relying upon rabbit for a singular food source, remember to eat the blood meats (heart, liver, kidneys) or risk protein deficiency.
Still, all in all - it fills the belly, and I would agree with Graybeard that it shouldn't be wasted.
