Little help with player casting detection

[ChaosSlayerZ]

Trev, perhaps you could help me with something related

Let say that I want to change race/put illusion on a pet when it spawns liek it was recently done for POSKY, but I want to do this for NPC pets.

Will

sub EVENT_SPAWN
{
quest::npcrace(69);
quest::npctexture(1);
quest::npcsize(4);
}

work for npc controlled pets?

If does I have even tricker question.
I ONLY want to alter race of a pet IF the NPC who summoned it belongs to specific race/class himself.

Can this be done?
Thanks! =)
