How to get rid of the smell of a cat spraying on the sofa?

How do I get rid of the smell? I hate the idea of throwing out my sofa but the smell is killing me.

Hello, There are products on the market that you can find in your local pet store or farm supply store that claim to get rid of this smell. I have found nothing that works truly well.

The best product I have found is D-Molish Now! by Neutron - Baby Powder scent.

My cat is nutered and he still does it when the male cats come around the house (all the time) and the females are in heat. We have a neighbor that feds strays.
My cats stay in but they still pester each other.

Febreeze.

I'm sorry to hear about your sofa but I had a brand new leather sofa and my male neutered cat pissed on it one time when he couldn't get to his litter box. I also had an Ethan Allen denim sofa that he pissed on. I had to replace the cushion on that. Needless to say, you will NEVER get that smell out. I tried professional cleaning, EVERYTHING over the counter and nothing worked. My leather sofa is out in the garage, I am sick everytime I look at it. It's been about 8 years since my cat pissed on the leather sofa and it still smells like it did the first day he did it. Let me know if you find a product that works. Good Luck.

pkees your response made me crack up. I have tired the products and none have worked. Sometimes the smell isn't too noticeable until someone spills a drink or if I leave the windows open to late and the damp air ignites the smell!

I would just get a differ couch, but there are products that will help you ,its best to have cats fixed young around 5 months of age,it worked for me my kittys dont spray.but I had one who did he didnt get fixed til he was two years old,he was bad but I think he was upset about the new kittys I got, I had him for 15 years he died in his sleep I never found out why .
