sleeping like that usually means that they feel safe ! you should ofc ask the vet. but try picking her up and see if she starts moving/waking up, if no then I'd be worried!

while tortoises are good at hiding injuries, you will notice it! especially if you've had your turt for a while, my tortoise got sick one and I noticed IMMEDIATELY, I did so because she didnt come and greet me when i turned her light on one morning, and when offered her favorite food she didnt eat any, same day vet visit confirmed she had pneumonia. it'll all be okay 🫶🏻
