Hi, I have a one and a half adopted tortoise named Tonto Marie. He's enjoyed the habitat we made for him all summer and is gaining weight. However, tonight I found out that our temperatures in southern AZ will be 31 degrees tonight and tomorrow night. Tonto is hidden in his tunnel, hasn't eaten the vegs we gave him in two days, and I'm trying to figure out what to do! Should we dig him out of the tunnel, or leave him alone? We have plenty of heat in his habitat, but he prefers the tunnel. I'm afraid he won't survive because he won't go to the heat source and will probably spent the night in the tunnel. I'm also worried about him/her not eating for two days, but we have grass and flowers, plenty of water around, and a nice habitat. He was healthy four days ago when I gave him a bath, but I haven't seen him since. Please give me info about whether I should dig him out of his tunnel and bring him inside, or if he will be okay. Thank you so much for reading this and for helping if possible. This is a great site!
