One of the coolest things I've seen done for ferret footprints was a friend who got a big (3'x5' or more) canvas from an art shop and a collection of tempera paints. Tempera is non-toxic, and easily washes off, so it won't hurt the ferrets. Spread newspapers on the floor of a contained space and put the canvas down. One by one, bring in a ferret, liberally paint its feet with Tempera and let it run around on the canvas. When it's done, take it off for a bath and bring the next artist out with a different color of paint. You can even save an area off to the side with one print from each to give a color key, like writing "Bandit" next to the blue print, etc. When it's dry, there is a spray that you can put over the paint to preserve the tempera and make it more stable. Viola! Instant art! Kevin [Posted in FML 6134]
