Eastern Kingdoms Safari

EASTERN KINGDOMS
Here is a list of all pets that can found by zone. I've done a fair amount of research and through personal experience, this is what I've come up with. Not everything is perfect, and mistakes are made. I have linked some wonderful addons/info for those who are hardcore pet owners. If you do find an error, please kindly leave a note with detail, so I may edit. The numbers next to the zones are the levels I've encountered. However, if you look at the ingame map, you'll see the levels of the pets in that zone.

If you're like me, and you enjoy rare pets, I recommend this addon: Pet Quality Notifier

UNKNOWNS - I have not learned the locations of these yet.
Cockatiel

Easiest way to get this:

Open your pet journal and set the filter to 'not collected' only.
Type in the zone name.
Click a pet and mouseover the pet icon (the one in above the 3D model).
If it is unique to the zone hunt it down, collect any of the others that you come across.
Move to the next zone and repeat.

Once you have all unique zone pets you should have most of the others, too.

Here is a list of all the pets that are required for this achievement known so far.

I also dont want to take credit for all the locations. Many where found by other, i just collected all the data and put m in a list.
Some critters are found on multiple continents and most of them needed for the Safari Achievement of that continent as well. If you catch one on 1 continent, you get the credit for the other Safari's as well.
