Summon Random Non-Combat Pet
/run CallCompanion(“CRITTER”, random(GetNumCompanions(“CRITTER”) ) )
I didn’t write it. Sometimes good information actually -does- come from the official forums.
See the official forum post for more information about “random mounts” (ie, the answer is long.. they said it well.. and i’m not going to repeat it.. except to say that the addon “livestock” looks like a very good solution).
