I just rescued a Russian tortoise from a Facebook garage sale site and don't know a lot about them. I was told my new friend is around 4 years old, a female, and healthy. From what I've been reading it seems she's had the bare minimum in life. She only had a heat lamp, no uvb. Only fed once a week. The only substrate is hay. I'm trying to buy new things for her this week. How does she look to you all? Any tips? I've given her a little kale and romaine the last two days, but I didn't want to make her sick if she's used to eating once a week.
