My russian tortoise only seems to come out to eat then I walk her and she goes right back to her hiding place once she gets back in her enclosure. I have had her for three months and she is definitely settled in already. She doesn't show any signs of being sick. She has clear nostrils, clear eyes. The temperatures are 95-100 on the basking ened and 80 on the cool end. Is it possible she is just "lazy?"
