I have had my Russian tortoise for a few days now and she’s not eating at all. I was told she only eats romaine lettuce , which she won’t touch, and she won’t try spring mix, dandelions, or anything else . She’d never had a hide and I bought one for her and all she wants to do is stay in it. As soon as I put her in her enclosure she makes a beeline for it. I’ve had her grazing outside as well but she doesn’t show any interest. I just want her to start eating something and then I can work on introducing her to different foods. Any suggestions are appreciated
