My cats do this as well
They're both neutered... I'm pretty sure they need the toilet.
We've altered the times they go out now, so they're out at night for a few hours, or if they come in they don't come in until last thing at night, in which case they'll sleep through til I get up at 7.
Ours usually claw my feet or the side of the bed right near my face
when they want to go out
