I volunteer with a small animal rescue and two sulcata tortoises were surrendered a few days ago. I have agreed to foster as none of us are familiar with them. I live in southern arizona and tonight it is down to 45. I brought them both in to my bath tub but clearly need to get a better plan. I. Know. Nothing. I will do some reading on this forum on basic care but right now I am curious about aging them and much more importantly what I need to do for them over the winter.
