Remember when we covered the mysterious Orgrimmar and Stormwind changes in Patch 9.2.5? Blizzard has now added new NPCs to the Orgrimmar stables area on the PTR.
The NPCs are Aetheil and her two pets Rips and Yuyu. You can pet the two pets, but they do not appear to have any other purpose for now.
Only time will tell if they are tied to the Dragonflight pre-expansion event.
