I figured with all the cat lovers here, someone might have a solution.

My room mate's cat, couldn't get to her litterbox as the door into the room with the box had closed and locked. So she wound up peeing and pooping on my couch. As soon as I discovered it, I sprayed and washed it with my really strong carpet cleaner.


But there's a lingering smell of urine.


So can anyone suggest anything to help get rid of the smell?

Thanks.
