Unfortunately I have not updated this for WoD just yet. There are MANY MANY pets with permanent visual auras/effect in this expansion, but with not that much info on the possibility of these effects interacting with anything taming related, I've tried not to update to avoid too much assumption/expectation.
I'll look into starting up and new catalogue.
I do suggest , U can experiment on them if any luck U found .. Just tell
People special effect pet does exist , don't think u wanna let blizzard to bring another extinction event on them . I believe people will go all out to look for them.
