Some Weird Pet Event?

I have received over 20 pets the same way.. it has something to do with xfers. 6 skunks and 6 dragons..

What did you do with all them? ._.

I don't have the Multi-Pet skill. And I don't see the point of using the pets that expire.
So then I have Four Perms.. my Baby Tiger, and three White tigers (one of which is my first pet, leveled up)

I suppose I can distribute the Four pets amongst my four main characters then.. though I wish I could Multi Pet the White Tigers and get the effect..
Does the Multi Pet skill only work on one character?
