Since Pio came in for the winter he is acting strange and I am a little worried. First he sat in his hide every day for a week, and didn't come out to eat, unless I took him out and then he only ate a few bites. Now he comes out every day and does something with this rock that is in his enclosure. He puts his two front feet on the rock and kind of lifts himself up and then goes down then back up. He does this for a while and then just sits in this position for the rest of the day and then goes for a drink and then into his hide for the rest of the night. He has been doing this now for three days. He isn't eating as much as he used to...except for cantaloupe which he loves. He just eats a little each day. I looked him all over and he looks good. If I offer him a worm then he runs for it...since the summer when he discovered them he just loves them. I have no idea what this new behavior is. I am getting a little nervous about this now.
