Let's say your in a situation where you need to hunt small animals and birds for food.... I know to discard a cotton tail rabbit if it has yellow spots on the liver, yet I don't know why? And, are there other animals that the problem is also true of such as... Skunks, rats, squirrels,birds of any kind. I have a wrist rocket in my bug out truck kit, and would like to know why no rabbits with yellow spots on the liver and some rules of thumb if I'm desperate enough to want to eat a crow, or weasel? Thanks in advance, love this sight.
