"Be careful, Mommy.  Be careful, " says my two year old live-in safety patrol officer Cameryn.  Nevermind that she flips off anything and everything.  I must be careful.  And the hamster should too.  We wouldn't want him to open his cage (the cage not only has a spring lock, but a twisty tie from the bread bag that prevents Cameryn from getting the hamster out unattended!) and fall 3 feet to the ground!
