Crescent Moon Creations is the name of a woodworking company owned by a guy named Rick Senior. He works for the City of Lake Forest, Illinois and designed and built a number of wooden cages for the Wildlife Discovery Center at Elawa Farm, which is run by Rob Carmichael and is part of Lake Forest Parks and Recreation. Rick's cages are all made from I think cherry veneer plywood with solid face frames, and hunter green contact paper interiors. Openings have bypass sliding doors with roller tracks for the glass doors. They're great looking cages but pretty pricey. Unfortunately I couldn't say exactly how pricey. You can navigate to: http://www.cityoflakeforest.com/cs/rec/cs_rec2d2.htm
and get Rob's contact info there. He can tell you more about Rick's cages if you want.
Here's a pic showing several cages made by Rick for the WDC.
