I did all kind of searches on the internet for details about this. Everyone says, yup, you can do it, but no one gives specific info. What EXACTLY does the blood look like under blue light? Anyone ever do this?? I wanted to use my girlfriend's cat for the experiment, but the idea was shot down

Try the new Surefire digital L4 flashlight...dangdest flashlight I have EVER used. Up to now I have used the 35,000 candlepower flashlights (a hundred bucks or better, and heavy as well). No more...The surefire is about as big as a regular sized cigar and is bright as anything you will ever see in the woods. The think that I like about it is that the digital bulb is actually blue light. However, the bulb has a phosphor coating to make it appear white. After I got it, I compared it to my other flashlights and the difference was stunning. Blood just jumps out at you on the ground. In comparing them, the old flashlights appear to be a yellow color that was never evident until I saw the Surefire beam. Amazing product. Again, if you want to try one, make darn sure you get the digital version...that is the one with the mind blowing bluish/white light. Sort of reminiscent of a florescent bulb. Excellent product.

Forgot to add: next time don't ask permission to experiment on the cat...just do it and explain later!

What's it look like-how's it show up?

I have looked at blood with a blue light, but not tracked.

The blue light reflects off of fluids such that the fluid jumps out of the surounding area. It does not just reflect off of the blood, but all fluids such as rain drops.

By far a bright white light is the best for tracking, but if the blood color matches other things of the same color, use the blue light it you will be able to see the blood better. This is of course if there isn't any rain or dew.
