is there anything that c reeps you out or grosses you out enough that even though you know its just pixels on a screen you just wont feed from it?

mine is the spiders...

Nords.... filthy savages.... I kid, I would say Spiders, Chaurus, and Falmer.

Nope I feed on all my kills, regardless of what they are.

I'm not into werewolfiness, but I would think spiders and draugr would both be pretty icky.

I'm not a werewolf but i imagine draugr would be really gross, it's essentially mummified flesh.

You can't feed off of the undead.
