Their mom did not "abandon" them. Female tortoises lay their eggs and go away, knowing that it is just how it should be for them. By instinct, they just do what is natural for them and what gives them and the babies the best chance to survive and grow! It's not cruelty, it's their natural way, like our natural way is to stay with our babies. Baby tortoises do NOT need their parents. They are born ready to go on their way. They do not know, or need to know, their mother. Not like us. Totally different.Their behavior is totally different from human. Today I just learned their mom abandoned them even before they become juveniles. That is probably why they are really cold blood
