It took my cats ages to stop the peeing, just as I thought they'd got over it one of them would do it again !!! I've ended up throwing out at least 3 carpets as I couldn't get the smell away, luckily as I decorate my home I started putting down wooden floors (thats was my plan anyway nothing to do with the cats) even then I would buy nice rugs and guess what, they'd do it again. After reading your E Mail I feel ever so lucky that they never did it on the furniture but my partner would go nuts 'thats it we're getting rid of them' then I'd turn on the waterworks and beg him to let them stay. As they got older it stopped and it would just happen say every 3 months which was bearable. Its a heart breaking decision to make getting rid of them but I can tell from your post that your at your wits end !

Maybe the cat you've got now can smell the previous occupants and thats why its doing it. Sorry I can't really give any advice as I had never had cats before myself and I guess I'm just lucky it stopped as I can't think that I did anything special. I just remember going mad with the cats and they obviously sensed my frustration and it seemed to make them worse.

I hope the more experienced cat owners on PT can help you out, fingers crossed !!! Good Luck !!!
