Crazy Cat Lady

Ok, If you want to get both achievements Nine Lives and Crazy Cat Lady, this is completely possible:

Information

1. 
   
2. For Crazy Cat Lady you need to kill her without killing any of the cats walking around with her ([npc=34014])
3. 
   
4. For Nine Lives you need to kill the [npc=34035] 9 times, this NPC is NOT related to the cats she have walking around with her, this NPC will be a summon from the boss
5. 
   

Steeps

1. 
   
2. Start the encounter with 0 DPS to anything, cats or boss
3. 
   
4. Just wait for the [npc=34035] summon and after is done, start killing him 9 times (You can count using the pools in the ground or with the buff he have showing how many lives are pending, but after the 9 times he will be gone so no big deal if you don't want to count)
5. 
   

In order to obtain this achievement, single target Auriaya without killing any Sanctum Sentries.

Be careful, the cats will easily die at 120 from thorns type abilities - my lightning shield made it so I had to come back again next week for the achievement!
