Thanks guys ...this is the first time I've seen him actually become active in the past 2 weeks; I was getting very worried. He's out and about today too so I've come to the conclusion that he has changed his habits to be up and active during the day (unfortunately when nobody is home for him--I've come home twice now to a rearranged enclosure...). Still not warm enough to keep him outside during the day and it won't stop raining either...
