These ppl have very cute cookie cutters - I know there is a giraffe head on there somewhere. They also make custom cutters, not sure how much they would be though. http://www.etsy.com/shop/PlasticsinPrint
There are tutorials online that show you how to make your own cookie cutters. If you don't have a large amount to make just freehand or print the image on card stock and use that as a template for cutting out cookie dough, use an exacto knife or even a small kitchen knife.
