I do. I spoke to Peter, and he was reasonably helpful.
This is the kanima's beta state. A great deal of violence and aggression can trigger the alpha state, which comes with the bonus of wings and an extra set of teeth. The kanima is a by-product of a bite on someone dealing with some kind of great emotional turmoil -- apparently, werewolf bites take the form to match the individual, according to what we've been told. That and love are the cures, apparently. And his venom is similar to that of some awful Australian snake.
He also suggested we shoot him a lot, but I vetoed that.
