World of Warcraft Small Pet has checklists, FAQs, guides to getting pets exclusive to the opposing faction, screenshots, extensive information for each pet, you name it.
Now, I have a fair collection of non-combat pets, mostly from seasonal events like the mechanical yeti from Winterveil and Willy from Children's Week. I also quested for the Sprite Darter Hatchling out of Feralas back when the zone was in my level range. But this site is for the serious collector.
Check it out and then tell me: frightening obssession or one more kind of pleasant activity to pass the time in-game?
