My OH had a tortoise when he was just a small lad.
They let it roam around the living room, everyday, every night.
It slept in his dads old slipper.
.
Then one day, they came in and couldn't wake it up.
They thought it was dead, which, in fairness, it could've been, but I said, it could've been hibernating. Which they didn't know they did.
They buried it. .....so, so sad. We'll never know.
