Wouldn't it be more fun to chase neighborhood cats around with the paint ball gun? You could offer a decoration service to the pet owners, have them choose their favorite color. I've seen some pet salons offer doggie and kitty nail painting, sort of the same thing.

How cool would tie dyed squirrels look? I can picture it now as the little critters come to the feeder in the morning. The conversations wit the wife "hey honey did you see the magenta Sciuridae that just scampered across the deck?"

I for one think the black and white skunk thing is passe, lets get some color in those stinky little beasts. Do you think it might be possible to add some perfume to the paint ball to make them a little more pleasant on the olfactory glands?

Birds might pose a little bit of a problem as I think about this in greater depth. What would be the outcome of a chickadee when faced with a paint ball arriving at a muzzle velocity of 300FPS. A little more color in the bald eagle might be nice but I think you should fit them with eye protection first so as not to inhibit their vision.

I look forward to more input on this subject. Would paintballs affect the meat when it is time to hunt these critters? Do you think unnatural colors might have impact on the mating rituals of some of these animals? Maybe some of them are on the kinky side and might like some glitter mixed in with the paint?

Awesome subject, I'm breaking out my paintball gun as we speak.
