In game we have only few achievements dedicated to cats. The most important ones are Crazy for Cats, because it rewards us with the right cat fanatic title, and Raiding with Leashes, because the reward is one of the required cats in Crazy for Cats.
Crazy cat Lady
Auriaya is one of the bosses from Ulduar - raid located north part of The Storm Peaks in the Northrend. This keeper patrols in The Inner Sanctum of Ulduar and is accompanied by her cats. Usual strategy is killing the cats, when boss fight starts, but for completing this achievement we want to keep the poor (tho dangerous) cats alive.
Crazy for Cats
Way to obtain all listed cats is in Battle-pet Cats section, except for Spectral Cub, whitch was unfortunately obtainable only in Asian region.
Here, Kitty, Kitty...
High Priestess Kilnara is boss in Zul'Gurub - dungeon located in Northern Stranglethorn at south of the Eastern Kingdoms. She is guarded by several cats called Pride of Bethekk. If you feed them, they wont be there to start attacking the group, when boss is at 50% health. To do so, group needs to catch Temple Rats running around the boss and throw them to cats.
Raiding with Leashes
All of the battle pets listed below are drops from bosses in classic raids. The drop chance on them is not 100%, so it might take a few runs of each raid to get them.
