thank you for your guesses, your poor english/grammar, and your overall lack of contribution to this topic.
To the point, when I queue with my guild and have to go cat, with a full bear spec in bear gear and bear glyphs, I am pulling about what you are saying you pull (somewhere in the 7-9k range) on heroic bosses. And I suck at feral DPS. The one thing I do know that I do decently is keeping up savage roar! =) I am actually going to try a full cat spec with glyphs and (hopefully) cat gemmed gear...but what I have has lots of dodge.
