I have a confession to make. I collect vanity pets. I don't mean I grab the ones from my race's capital and then the ones that go with holidays. I mean I hunt them down, build them, buy them, and do quests I would rather skip because the reward is a pet I'll probably never have out.
How did I end up this way? I guess it started in the Undercity, where I bought a cockroach. In Orgrimmar, I figured the cockroach might like a few snake friends. It wasn't long before I ran out of pets I could get that way, and I wasn't high enough level to get any pet-related quests yet. So I started pouring my gold into pets from the auction house. My gear was from quest rewards because I almost never got drops I could use and my gold was going to pets. I eventually started buying gear first, but I still have trouble forcing myself to buy enchants and consumables when there are pets to save up for.
I have two favorite pets. One is my Dun Morogh Cub, which my husband bought and rode out to Coldridge Valley to give to me. That bear has been by my main's side since level 1. My other favorite is my Phoenix Hatchling. A friend said he'd run Magister's Terrace with me as many times as it took for me to get it. I was a level 70 hunter with BM spec, and he was a level 80 protection warrior. I just couldn't put out enough DPS for us to take down Kael'thas, so we called in another friend to help. It was my first time through there, and I left with a fiery bird flying along behind me!
The one pet I really wish they would add is an Azerothian Schrödinger's Cat. It could be a reward from a quest involving gnomes or the D.E.H.T.A. The worg pup can be either black or brown when summoned, so a cat could have normal and skeletal models to switch between. Since you wouldn't know if the cat is alive or dead until you summon it, the Copenhagen interpretation of quantum mechanics implies it would be both alive and dead while unsummoned.
Do you collect vanity pets? Which are your favorites? Is it too early in the day to think about quantum mechanics?
