Yeah eventually we did, it took a good few months though, and if it was a hot day and the car was left in the sun with the windows up you could still smell a faint whiff of it! That car was smashed (not my fault...crazy Qld driver in a Victorian car!) and written off a few months ago, so don't have to worry about it anymore!

Cat pee has to be one of the worst smells to get rid of...
