Tortoises get to heaven way faster than humans do.
The Pope, and I am not Catholic, said animals go to heaven. Pope said, I choose to believe him with that. Done deal.
I am very sorry for your loss. I think we all know how that feels. Your heart is heavy and your are, well, grief stricken. It hurts. We all know that hurt.
Every spirit goes to heaven including animal ones. Your tortoise will be with you, even when you feel most lonely remember he is in heaven watching over you right now
