I just saw that it may go as low as 38F tonight here in S. Florida. Never happened since I began raising Ponce my 5 and a half year old m.e.e. He's big and lives outside (carapace is more than 14in.), weights 20lbs, and has stayed outside when temps have dropped into the 40's at night because it always warms up during the day. Any risk in letting him stay outside? I assume it would be more stressful to bring him inside, but I'd appreciate any thoughts. thanks!
