We now have official confirmation from Blizzard (via Wow Insider) that one of the pets we listed as a possible removal is definitely being pulled when the cataclysm strikes. It's true... the Razzashi Hatchling from Zul'Gurub (along with the Swift Zulian Tiger and other mounts) will be unobtainable when patch 4.0.3 hits. So if he's on your list, he should be your absolute TOP priority. Even if you've already got him, we suggest farming for extras. Since he's doesn't bind when picked up, he can be sold to other collectors in the years to come. We're guessing his auction price will be the highest ever for a companion, so he's well worth stocking up.
So what's the good news?
Well, Blizzard has broken their silence on which items will no longer be available in the near future. It is possible that they overlooked an item or two. But this announcement does make us feel better about the chances of the other 5 pets we've been watching. With Blizzard's official statement, we're optimistic that those other pets will still being available (in some fashion) after the world changes.
So breath a sigh of relief and go farm some baby Razzashies!
