My little rattie Maya, who we've had since she was old enough to take in, has a huge shoe fetish... but only ones my 6 y.o. has on his feet!   She'll always try to bite them from when he walks in the door to when he takes them off.  Doesn't bit anyone elses shoes, or his when they are off.  Doesn't bother feet.   It's the strangest thing.  Any ideas?

Button's breeder gave socks to the puppies to play with, so to this day she has a fettish about socks. She will nibble at anyone's feet who is wearing socks but without their shoes on. But she hasn't bothered shoes (laces mostly) since she turned about 2 y.o. But she was pretty bad about messing with all shoe laces that wiggled on people's shoes as a puppy. Maybe Maya is just going through a puppy phase she'll pass out of like Button did with shoe laces.

Now if I could just get her to leave socks alone. LOL
