One of my friends had several cats urinating (territorial thing) in her house. In order to sell the house she removed and replaced large sections of the sub-flooring, plus large sections of dry wall and mop boards. It was that bad. On the bright side, her house smelled fine by the time she was finished. You might have to take measures like the ones I mentioned...I hope you find something that works

I believe Kilz oil-based primer can be used to prime the walls and get rid of the smell there. As far as the floor, I personally think the only thing that works is replacing all of the affected flooring down to and including sub-floor. Otherwise it seems that you always have that smell.

There are enzyme cleaners available at places like petsmart that really rerally do work. They "eat" the offending substances. Before I did anything like replace carpet, I would pop for $30 or so of Nature's Mirical, saturate the area....let it dry and repeat.

Lindac and Meghan- I have probably spendt over $100 on enzyme cleaners-!! It was the Kilz that I used on the floor- I was thinking the name started with a Z- oh well, it had a Z in it! I think Meghan might be right- I might have to go down to the subfloor- that is what I did when I first bought this house and found a place that a cat must have gone on. I then tiled over the floor after I replaced the subfloor.

We had a male cat 10 years ago that sprayed in our house. When he went to heaven we tore up the carpet and used Kilz on the subfloor. It worked fine and no odor remained.

My sister bought a house where the previous owner's cat had peed. Then her one cat started doing it. Three houses later and 5 years later, her one cat never stopped.

I love my kitty dearly and he has never had a problem. But, I will hesitate to move into a house that had cats (especially multiple cats) for this reason.

Have you tried an enzyme cleaner called consume? I swear by it. You find it in janitorial supply centers probably. But don't use it with warm water, it will kill the enzymes and let it dry before rinsing.

victoria- We don't have janitorial supply store here, but I can look for it online. Why not use warm water- does it become less effective? Thanks
