I took over parenting of a Russian Tortoise in May of this year. I live in a valley north of Los Angeles where daytime temps during the summer run 90-100 and are all over the place in the winter with nighttime lows that can drop into the 30's and low 40's. Tortoise is about the size of a paper plate. I have kept her outside in an enclosure I built. With the nights cooling down so much I am afraid to keep her outside. Unfortunately I have very little indoor space. I am at a bit of a loss at this point with winter care for her, hibernation, etc. Can anyone give me some advice and guidance on this? Thank you!!
