If so, do you let it harden before removing from the mold? I am needing some animal shapes for a zoo/safari cake and I though this would be an easy way to achieve it.

Sure. Mold them (I usually dust the mold lightly w/ cornstarch) and remove right away. Allow to dry on a flat surface where air can circulate--like a sheet of fun foam or soft foam cushion.

yep,dust with corn starch

Depending how firm your fondant is you may have to refrigerate or feeze the tray to make it easier for the animals to come out without distorting their shape.

Just did it and it worked great. Thanks so much to all of you.
