...At least in our case. Little Penny has a toe tattoo and can hear treats being offered from a mile away. My boyfriend also claims that she comes running when he unwraps a Klondike bar! But we *are* curious what the toe tattoo means. Penny is so hyper that we were wondering if maybe MF tattoos their "potential ADD" ferrets... :-) I've been reading some of the explanations on the FML but they don't make too much sense to me.
