Hmm, I think with the last Buffy and TVD vampires (not so sure about other kinds of vamps) the deal was that they don't ping the Slayer senses like Whedon vampires do. TVD vampires are very alike regular humans physiologically, they have a heartbeat and they do need to breathe. And they can eat/drink human foods. Basically, their bodies work like that of a normal human as long as they keep a steady diet of blood, otherwise they start to desiccate. The only difference is that they feel cool to the touch, hence why they drink coffee to get the caffeine rush that warms up the skin.
I haven't yet publicly revealed Katherine to be a vampire, but that was my intention before my hiatus so it will likely happen soon!
