I’ve actually been farming the black tabby for the last few weeks and while the droprate kinda sucks, plus having to camp a rare that’s only hostile to Horde, it’s actually not that bad. They’re worth around 1-2k gold depending on which faction you sell to and it only takes me a few minutes a day and a little luck. I had no Horde toons so I made a quick Belf DK and camped her at the spot and now everyday before I play my Alli toons I hop on her for 30 seconds to see if the rare is up and then log. I’ve nabbed the rare about 16 times just doing this the last few weeks which got me 3 black tabbies even though I know there are a few other consistent campers there with me. So that’s a few thousand gold at least for maybe a couple hours work if you factor in the time it took me to get the toon leveled out of the starting area in the first place. I believe I have at least 90 vanity pets now, including the black tabby and still have a handful of other rare ones to work on. So for all you other vanity-pet lovers out there, here’s just another more obscure one to look for.
