You could use a gorilla for pummel to interrupt (manual cast, I think), however I don't know how worth it it would be. I personally don't have issues dpsing the add without an interrupt... at least in 10m, haven't had a chance in 25 yet.
Does anyone know if Deterrence causes you to avoid a bite? I have always assumed it does and I haven't tried it out. I may "accidentally" pop it before I get bitten tonight and see.

Does not prevent it. It's a bit a of a pain to sift through the logs for when I pop deterrence and other things to update this list, is there an easy way / proper way of doing this? I just went through all my death logs because I remembered this happening.
