Dan, since you are in CA I can't speak for the rabbits you have. All of my experience is with the Eastern Cottontail but I'm sure there will be many generalities that apply to all. First of all , the white spots you refer to. The liver is where I normally see spots. Notice I said normal. Rabbits keep their butt on the ground so they get various worms in their digestive tract. 100% of rabbits will get them. This is normal and a year round occurance.Don't be alarmed when you see the liver spots. Just a reaction to the worms in their body.Just don't let your dog eat the organs.Also, wear rubber gloves to protect yourself from blood/body fluids,etc.Rabbits are known to carry "Rabbit Fever"(Tuleremia).If you have compromised skin you can get it too.Gloves work.Ignore the ticks and fleas.The best warning you will get from a diseased rabbit is one that doesn't want to run when it should. If it seems sluggish or disoriented, best just shoot that rabbit and discard.Another thing, here in my part of the country we have a plant called poison oak.Rabbits eat it just like every other plant that grows.Another reason to wear protective gloves when you skin/gut 'em.Don't get psyched out by all these warnings. Diseased rabbits die quickly and chances are the rabbits you will see will be normal and healthy. Just remember what normal is.Hope you shoot all you want air gun bro.Dave.
