Ready for bed, I realised that I'd not closed the van up so I trotted down and closed it up. Next morning, I trotted down again to open up. As I did, I was met by next door neighbours cat, sprinting out of the door. IT HAD!! a pile of ---- on the carpet next to the toilet, (right area). Spent all day scrubbing carpet and floor. As I started I couldn't breath, nought worse, than a cat. Anyway carpet on the garden seat, van vented but, try as may to get rid, there still seems to be a whiff about.
