The Cave Canem Demos is a compilation album by Cuban Americandark cabaret singer Voltaire. It was released on June 9, 2012. It contains early demo versions of some of Voltaire's songs that would ultimately appear on his first two studio albums, The Devil's Bris and Almost Human, with the exception of "Life", a previously unreleased track which has yet to see a studio re-recording and the only song of the album to be not written by Voltaire himself (it was written by the demo's producer, Scott Pittinsky). Those recordings trace to as far back as 1989, and Voltaire used to distribute them during his first live performances.
"Cave canem" is a phrase in Latin meaning "Beware of the dog".
