Hi I just got a 2 year old female red foot tortoise. I've had her for about a week and she was eating for the first 3 or 4 days and now it's been 4 days and I haven't seen her eat much of anything. The food that i give her she won't touch. She has a large enclosure and lots of variation in her diet. I'm thinking maybe it's stress, and I don't know what to do to make her eat again. Any suggestions?
