IF you can get the carpet out then DO so, it'll have seeped into the underlay...then when you wet extract it'll just keep pulling the piss through.
Plus you'll more than likely lob water on an flood the floor below...
Take it out, short term loss.......................

it wont vanish quick esp if its pour homme la Tomcat as its very acidic hence it stinks..hope he drinks well as like us our piss reeks when we dont drink enough, plus he has shag glads involved
you need to kill the acididity,and ammonia.

I hate my career life real tears

Anyways Then clean carpet using your chosen carpet shampoo "LOW FOAM" and a STRONG industrial odour eater(below) mixed in with it, dont be shy neither.

Ideally it needs to dry outside in a good frost that'll kill it off, DONT wap the heating up makes it worse just get AIR in.
then regular misting or light extraction using the chem above, say once a week when you clean car...
If it was vomit you'd be proppa fcuked

Erradication takes time...Masking takes minutes and lasts so

Good luck
