Do vampires urinate/defecate?


For all the attention paid to vampires consuming blood, there is little or no literature about how what they take in goes out afterward. The only book or movie I know of where this is addressed is Hotel Transylvania where a single throwaway line mentions Dracula changing his daughter's diaper. Does anyone know of any other precedent for vampires relieving their digestive systems? There's no one size fits all answer as vampire biology varies depending on what each author decides.

I would imagine that they do in most cases, it's just that most literature and films don't bother to get into the specifics of that. However, The Strain trilogy by Guillermo del Toro and Chuck Hogan actually do cover this matter.

All bodily waste is excreted from a single rectal orifice in the form of a pungent ammonia-based spray; a vampire will excrete for the entire duration of a feeding, purging old food as it consumes new blood.

I would suggest reading the books if you really like vampires and realistic biology behind them. Thankfully the show is premiering next month too!

Fascinating. Guillermo del Toro is pretty inventive, and Chuck Hogan is a name I've heard in good context. This series must be interesting.

Indeed. I appreciate Guillermo's new take on vampires in both The Strain and Blade 2. This show looks like it will be really good.

Depends on which iteration you're dealing with. Some authors/creators say yes they do while others say no they don't. Just like some authors say Vampires can eat whatever they want it's just the blood that sustains them while others say they can't digest anything but blood.
