Cat pee smell!!!

[OzJavelin]

Urgghh!! Got in the SV8 this morning (it sits in a carport) and the inside of it stinks of cat pee!!?? I can't see anything obvious on the outside, but the only place I thought it mght of had a chance on smelling up the inside would be the windscreen and it running down into the plenum chamber? I've hosed that out and it still smells inside. When I get home from work tonight I'll give the car a good clean inside and see if that helps.

Any suggestions on how to get rid of the smell?

[ BTW: I think I'll be getting a trap from the local council .. ]
