That scratching in the attic, that bump in the night, that howling on the wind ...it could be anything!  Or perhaps you saw some creature which you swear doesn't have a listing in the Audubon Society Guide To North American Mammals. Well, don't trouble yourself over it any longer.  Just call our crimestoppers and we'll discover the identity of the culprit.  We carefully examine every bit of evidence.  Footprints! Hair samples! Excriment samples! Telltale odors! Scratch marks! Chew marks! Bedding material! Hole size! Type of noise! Environment of animal! Time of year! Time of day! DNA evidence!  By golly, if it's there, we will find it and bring it to justice. Call our crime lab any time.
