Found one poor quality outside the cave but several at the back of the long winding cave (uncommens and poors). Killing the yetis didn't spawn any for me, the yetis respawned but the pets didn't.
Just got mine at 1:30am--circled for 15 minutes with competition. Didn't have to kill anything to spawn, they seem set on 5-10 minute intervals. Good luck!
