My third 70: a draenei hunter named Corissa, and her pet ravager, Fluffy. I believe the technical term in the hunter community is FO'SHIZZLE!
(Yeah, I don't know what it means either, but it seems appropriate.)
I tamed Fluffy at level 10, and it's been my only pet all the way up to level 70 (aside from temp pets tamed for skills). It's interesting how some hunters focus on one pet, and others collect many different pets. I'm full Beastmaster, because that was the only spec where my pet could actually hold aggro, but I have no desire to get any exotic pets.
