Okay, speaking of pet farms this one is a really unique farm.  What we're looking for is the carrier cage : black tabby.  This is a very sought after pet for both horde and alliance – which is why its price competitively at 55,000g.  The farm takes place in Hillsbrad Foothills on a peninsula like piece of land just northwest of the yeti caves.  There will be dozens of stormpike engineers surrounding ballistas that only horde characters can kill.  However, that doesn't mean alliance polayers can't do this farm (im alliance myself).  All you need to do is to create a class trial (monk is the best) and send him over to the grinding spot.  Use the black ox statue to attract the mobs, and easily maul them down group by group.  If luck is on your side, you can make out with an awesome black tabby carrier.
Even if you don’t have flying in WoD be sure to get the WoD handy notes. If you have flying simply fly and pick up all the treasures that you can and do bonus objectives. Not every single piece of treasure will be worth it though as some are hidden in caves or are just hard to get. So if you find yourself spending more than a few minutes finding a treasure, just skip it and move on, there is plenty of treasure to go around.
The entire Jade Forst is our farming spot for this one.  Literally, the entire Jade Forest.  The Jade Forest is crawling with porqupines and if you have a mage character, each one of them has chance to drop the polymorph porqupine tome.  Which is excellent, because these tomes have a selling point of 13,000g across the board. They are really easy to get, and noone really pays attention to these spots.  Try it if you like, I was able to get 2 on video, and have already sold one of them.
