I've had my Russian tortoise since i was about 8, I'm 21 now and i've noticed recently she hasnt been eating. i live in chicago and it's late october and getting pretty cold, i THINK that might be something to do with it, but i dont know. i moved her to a much warmer room and put the heat lamp closer in her enclosure. i have noticed the only thing she wants to do around this time of the year is dig and sleep, but shes never gone this long without touching her food (about 3 days now). i've cleaned her tank, bought a new bulb for the heat lamp and give her fresh food when i see the previous food dried out. i have never hibernated her before either. does anyone have any ideas?
