Open Question: my ferret goes insane over feet?

[feedcrawler]

my ferret is is very gentel and rarely nips, but he has a strange problem with feet. no matter what everytime i take her out the cage she goes after any1 without shoes to bite there feet. dont think just a lil nip, she gets on attack mod and bites really hard.she even jumps into the air with u lift your feet up. im wondering if my ferret has a strange hate or attaction to feet. i love my ferret but her lil foot fetish is annoying me and my family. this isnt a once in a while thing , but everytime she out of her cage.
