Welcome to the forum! Sorry to have heard that your tort has been giving you "trouble." I have had a Greek tort for more than three years. Recently I've been having difficulty with its food...it used to eat only lettuce (Roman) and now it won't even eat that! I've tried other food but....NO WAY. As for the temperature well it's still quite warm here, so I don't think it's the weather and time for hibernation. I don't know what on earth is wrong.
Goodluck with your tort.
