Cheers John, just been out there, pretty much did as you suggested, the poor fella couldn't even face going upstairs let alone in the room where he found him, I cut up all contaminated carpet & underlay,bagged and taped it up leaving it for him to dump, the blood hadn't penetrated the carpet but the urine had, big time so he was obviously a repeat offender, the floor was moisture resistant chipboard so i don't think it's penetrated, i sprayed it with clensan, if it still smells in a couple of days i'll replace the damaged section.
