its weird i have 4 easterns one big female i just got she was in her blue phase when caught, i brought her home and 2 days later Ekoh went blue, and i just get home from a day at Kennywood and kind my smallest one full on blue. i got one more Amaunet and if she goes blue within a week i would say something is definitely going on whether it be hormones or a coincidence. without LOTS of testing we will never really know unless everyone starts noticing these trends and someone doing research can look into it (preferably not that Hoser guy though lol)
