We experience this "phenomenon" as well. It's quite aggravating sometimes when everyone is on an emotional roller coaster at once...and there's not enough chocolate to go around. -.-

But I've noticed my snakes do the same thing. Madison, my baby BP, shed Monday. Tuesday Cheesecake, my corn snake, was blue, and Wednesday Cleo was blue. I'm waiting for my last BP to go blue XD
