well just wanted to share this with you there is an achievement in your cooking tab called critter gitter Critter Gitter - Achievement - Thottbot: World of Warcraft heres the link now all you have to do is get 10 critters to be your pet within three mins to do that you must have Critter Bites - Thottbot: World of Warcraft obtained from the cooking vendor for 3 cooking daily marks.
Now once you have the 10 critter bites then your all set. First you must find a group for gundrak(instance in zul drak) then you clear the first couple mobs up the boss named slad'ran now behind him you will see critters called fanged pit vipers these are your targets there you will use the 10 critter bites and get control 10 and get the achivement. now this a theroy but iam hoping this will work and iam sorry for not supplying a screen shot but hope this works and gl
