I started to farm for this pet after spending time farming for the turtle mount. Since I was around Dalaran, I thought I'd try my luck. I guess Blizz took pity on me for grinding pets/mounts with absurdly low drop rates, and I managed to get the rat to drop in 30 casts!
Using the addon Rarity; (from Curse) it calculated:
7 Magic eaters
1 partially eaten fish
13 sewer carp
3 drowned rats
5 crystal vials
1 giant rat
To those who haven't gotten one yet, keep farming! + side, you stay in 1 spot! :)
