I don't make it a habit to eat my catch but I have had muskrat a few times and I had beaver once. The raccoons are ok if they are prepared right. I have heard of a few people who eat bobcats but that might not be true
THere is a video called after the catch its about 4 hours and it shows you how to skin fox, yote, coon, bobcat, skunk, otter, mink, rats and beaver you can find it at minnesota trapline products
Hope this helps
