OK, as most of you should know, lots of wolves have fleas. Foxes...I wouldn't know...Well, here are some techniques that I have tried and there levels of effectiveness (-10 to 10).

Running really, really fast (so fast in fact, that your molecules spin and/or vibrate out of control and split you down the middle, obliterating your left half.) Effectiveness: 3 kills all fleas, but you are dead no longer of this earth....

OK, maybe I haven't tried all of these techniques...

Rolling on the moist ground indefinitely. Effectiveness: -8 flea count increases by 60 percent.

OK, you get the idea.
