for the past couple of months i have been offering my 8 balls meals every other day. they have been eating every 4 days or so. for the past 2 weeks they have cut down considerably. i have kept temps at 85 day and 75 night. the only thing i can think of is that the daylight has shortend over the past month -they are in a room that is naturally lit - but i did not think this would make a big difference. any ideas. thanks
