This is most likely not working as intended because I highly doubt blizzard intended for a pet you needed to be exalted with a faction to buy. So basically you have a friend that is exalted with them cage it and trade it over to you. If your already exalted with The Kalu'ak you could probably sell them in trade for a decent profit till fixed. They are only level one so they can be sold to anyone. Most pets like this are non tradeable hope this helps a few of you. If they do not fix this eventually still could be a guide for making some decent gold on the AH. =3 cheers
