I went ahead and bough a couple mice from Petco. Don't know who packages "The Gourmet Rodent" but will research it. It looks like a nice, healthy (frozen) mouse.

However, the best part is the packaging. At the bottom, it states "Contents: Crude Protein 55%; Crude Fat 23%; Ash 11%. Hmm....well, now I know what hopper mice are made of. The other great statement is "not for human consumption." Darn!
