Cat's & Dog's only no Werewolves?

I definitely feel like wanting more Supernatural beings! Aliens and Vampires is just not enough... I definitely am eyeing at possible mermaids, witches and most definitely werewolves, that are as good as vampires and of course their natural enemy! I am sure it would be epic to have a full fledged werewolf, that was worked on as long as it was done for the vampires, just to make them the most epic iteration yet!
