There are a lot of awesome sites out there for hunters and our pets. Here is a list of places I go when I need some help.

Forums:
elitistjerks.com/f74/ - Best forums ever for hunter spec/class info and theory crafting


Pets:
www.wow-petopia.com/ - This is by far the best site I have ever seen for hunter pets. They are the first with news on the pets and have a great picture gallery for when you are trying to find the right pet skin.
www.wowhead.com/?pets - Wowhead is also a great resource and will go on to give details other sites dont have.

Hunter Blogs
tkasomething.com/ - Fun and informative blog
www.maniasarcania.com/ - Need to give a shout out because the author of this blog runs petopia and has given great info for as long as I can remember
