Tonky is home!

He was well enough to be sent home today.
He is eating, drinking water and peeing,
The one thing that seems odd to me is that he is lying inside the litter box.
What can cause this? Is it because he got used to sleeping near the litter box inside the cage at the hospital?
Is there anything wrong because he wants to lay there?
Thank you.

His smell is no longer on anything in your home, but the litterbox does smell like him. It's a comfort thing cats do when they're in a new environment.
