Of course, over the course of leveling, I had to abandon her (leveling pets was nowhere near as easy as it is post-Patch 3.0.2) but these days I keep the company of Leech Widow from the Wetlands. Yes, it's a generic white spider, but you'll understand these things if you have a Hunter. The cool thing is, Spiders now appropriately have the Web ability that we only used to envy from NPCs. It entraps opponents for 4 seconds from 20 yards and has a 40 second cooldown. It's a damage-less version of the Exotic Pet Silithid's Venom Web Spray. The good news is, the damage doesn't really matter. You'll want to use the web merely to keep opponents at a distance. This ability makes them a great choice for Level 19 twinks.
