I was just having a very good bonding session with him, he was loving the stroking and I was chatting away, but then I moved to sit more comfortably next to him and he got scared and ran off behind the laundry basket.

I didn't mean to scare him.
I guess at least he's not in the litter tray anymore.
Should I just leave him alone now until tomorrow? Some advice says don't leave alone, just be in the same room as him, try to stroke him if he'll let me (which he will), but I don't want to scare him again and make him associate me with being scared.
He's currently confined to the bedroom, so I'll be sleeping in the same room as him.
