Just worked out what the white eggy things are that he's been leaving on the furniture 
He's got rice grains around his bum, so it's tapeworm. Vet is giving me a series of long term treatments later as he said it might take a while to shift such a bad case.
Do I need to treat the kids? And me? I am pregnant, should I be worried?
I am so grossed out, absolutely hate the idea of anything living in me or on me!
