My son's GF moved in with him a few months ago with her neutered male cat. The cat appears to have it in for my son and pees all over his stuff. The latest casualty was his guitar case.... I just gave him a drive somewhere with his guitar and almost died at the cat pee stench. He has tried a few different commercial pet odour removers that promise to neutralize cat pee but none of them have worked. After seeing a discussion on another thread here about barbasol shaving cream neutralizing skunk spray, I thought I'd see if anyone has any magic solutions for cat pee (and suggestions on how to get the cat to stop doing this... I have a permanent solution, lol but I don't think they want to hear it!).
