true, in my old house, i had five spirits livng there, but only two actually did anything. one was close with my mom and the other's Rori. after the move, only Rori's around.
^_^ cute. i have no idea with animal familiars [have had the spirits of my pets stick around for a while but that's about it] all i know is to find an animal familiar is a rare bond, the animal is born your familiar, not trained into it.
