Thank you all for your answers, which I did not get until this morning.
When I got in last night he was a bit quiet, but not poorly in any other way. I sat with him and made a huge fuss of him until bedtime, which funnily enough he loved. This morning he is back to his old self, bringing toys to play with, waiting for a cup of tea and trying to rip my arm off with his play ring. The only thing he can't do is, well, poo! And no more accidents at home. I even got up at 2 this morning to make sure he was ok and let him out, just in case!
