ok, does anyone know how to temp color a rats fur that wont harm them. heres the deal im goin to school for special fx makeup. so one thing we try to do, is do student films, and the school is pretty much a horror school. and i was thinkin of using my rats in a film. and so you know all precautions will be taken to make sure no harm should come to htem. if theres a chance it wont be done. but i was thinking you dont really see white rats in horror films. and i was thinkin maybe there is a way to temp color them to kinda look like wild rats. anyone know of anything.

Well... The closest color to agouti you're going to get is brown.
You can mix red, blue, and yellow food dyes to make brown, but it wunt be perfect.
You also should keep it away from eyes and nose.
So they're prolly have little white circles...
