SO I've spent well over 100k on companions in AH the past year or so and currently have 148 pets and plan on getting my final 2 Darkmoon pets before MoP but currently on Beta there no achievements for having pets (only pet battle point achievements) I only really got all those pets for the achievement as that's what I love doing in WoW. All that gold and time wasted?
Apparently there are also 500 pets in the spell book for companions xD
EDIT: Guys real sorry I found the achievement it's listed in pet battle area and is now known as Collect 150 'Unique' pets. Not sure how to delete thread? Thanks for the replys
EDIT: Wont delete thread for future concerns on the matter
