Fawn

I would recommend people to catch it in grizzly hills. It saves you the hazzle of leveling it a lot. Since in grizzly they are around lvl 20. They come in as secondary to the grizzly squirrel. 

Happy farming! :)

Battled and Trapped my first Fawn at (76, 70) in Elwynn Forest, you should have seen the look on her mothers face :(

Got a rare fawn when leveling in Elwyn, and she's been in my core group every since. 

Just picked up a rare in Grizzly hills. She was second (or third) to a Grizzly Squirrel. Lots and lots of poor quality fawns, but hung in there and searched for a rare. Found her, she's awesome. Heals, hits like a truck, really good pet. She weakened to 20 on capture (was L21). Her stats look like this:

Rare

1100 Health

205 Power

244 Speed

And she's so, so adorable! About 1:20pm server on Whisperwind. Happy hunting!

Just captured a L21 rare just north of Amberpine Lodge as secondary to Grizzly Squirrel

The highest concentration of fawns seems to be outside the gates of Stormwind ( a sticky spot if you're horde), but you can also always trade in your lvl 1 for a higher lvl in Grizzly Hills.

Traded in my Level 1 for a Level 21 in Grizzly Hills South of Alpine Lodge mixed in with Grizzly Squirrels and Skunks
