This care sheet: http://www.reptilesmagazine.com/Eastern-Box-Turtle-Care-Sheet/ suggests that EBT caregivers can leave their turtles indoors at home for "a week or so" without food, lights, or heat while they go on summer vacation. Scroll to the bottom of the care sheet to see that section. It does specify that you should stop feeding the turtles for a week prior to leaving for vacation to allow the digestive system to clear, similar to preparation for winter brumation. It could effectively be similar in timing to a summer aestivation period in the event of extreme temperatures, only without the heat. Has anyone ever tried this?
