I came home from work early and I could not locate my two Russian Torts. They have been in their outdoor habitat for about three months now and they have their usual places but today, they were either not in them or much deeper than normal. I got some extra mulch and added about 5 - 9 inches over their usual spots and then covered the entire garden in plastic and bed sheets. It will be 27f tonight and only about 40 tomorrow. Is this a tolerable temp for buried Russians? I am hoping they have been able to acclimate in time for the front. My adult boxies have never had an issue but they are locked inside their hibernation suite in the garden. I am going to worry all night I think.
