I have had my female Russian tortoise for two years. According to the vet, she was small when I got her. In the last week, she has been really restless roaming her 2x3 foot cage. I did change her light bulb due to needing to be replaced. She is also eating very little. I have noticed she is eating her substrate. Her normal diet is romaine lettuce, red leaf lettuce, radicchio, and will occasionally get small amounts of kale and spinach. She has zero interest in her food. She still has a lot of energy. I just dont know what to do to help her feel less restless. Thanks for the help!
