>>1970602like hannibal in the tv show says: Honor the animal by using his whole body.
you did a bad thing, killing a small animal that never got the chance to reproduce, let alone grow meat on its bones. While forests are getting emptier and emptier.
Kill an old deer that has already reproduced, lived its life and has meat to feed you.
There is one thing you can do remove the guilt, since i see you have a consciousness at least. Buy some seeds (heirloom, not hybrid) something that the animals of the forest eat. Be it berry bushes, strawberry cuttings, carrots. And go in the forest and plant a couple. Give something back.
