Actually, a couple of months ago my father in law asked if Hadley was the new hedgehog. He obviously remember that I used to have hegehogs as pets (though not for seven or more years now) and did not know the difference between a hedgehog and a guinea pig. Though I'm not surprised, sadly my in-laws don't show any interest in all at anything the the kids and I do and never have, so not having a clue about the family pets is par for the course.
