Hiding/Covering urine smells outside

Just a quick question; I need a product to get rid of urine smell from an outdoor stray that keeps spraying/peeing around the front door of my apartment where he sleeps. Is there something inexpensive I can use to cover a big area? I have a little Knockout but its not the cheapest stuff in the world. Even if there is just some household product I can put around the bushes, I don't necessarily want to keep all cats away, just cover the smell until another smelly male comes around.

I am trapping this cat this week (hopefully) because we have a cheapo spay/neuter clinic this week at the shelter and I want to get him into it. He is the only real stray left right in this immediate area (for now anyway). There are no ferals (I already took care of that problem) and he is all alone and hangs around here by himself. He basically lives in my front bushes. So it's not like there are tons more that will just mark when he is gone, like I said, for now anyways.

I am sure this question has been answered but I am never successful when I do a search through old posts.

Thanks.

You might want to try a urine remover that's used for carpet cleaning. It may not be the cheapest thing, but I have a large bottle of enzymatic cleaner that I bought for 8 dollars, but that can be effectively diluted to something like 5 or 6 gallons to clean carpets with.

www.urine-off.com Hands down the best product I have run across for this problem. And although expensive, it lasts a long long time-
