I live in Pittsburgh PA and have been putting my Sulcata Petey outside in his pen everyday. My question is with the year coming to an end and the temp slowly dropping, how cold is to cold for him to be outside? I still bring him in every night so my question was just daytime temp. Thanks A little side note....I know every time I post about him I also mention how amazed I am about how fast he is growing, well I'm still amazed! Just wanted to say thanks for everyone who has helped me since I got him in keeping him healthy and allowing him to grow like a weed.
