Half Vampire doesn't exist as a template. The Vampire Template is extraordinarily powerful, but then you die in sunlight, which is about 75% of the time in the game. Vampire is NOT a good PC template for main characters. Furthermore, Vampires cannot be ressurected, again making it not work at all.

As far as the dog and cat people, just due to the random things that exist I THINK they are in Faerun somewhere. I'll see if I can find a stat block link. It's entirely possible that they don't, though, and wouldn't fit the setting.

Oh, and Druids actually don't need to have the first part of their alignment be neutral (Neutral Good, True Neutral, Neutral Evil). In 3.5 they just need to have Neutral in their alignment somewhere.

I'm looking for more information, hold tight.
