Carpet cleaning might help. I've also heard A vinegar water solution would get the smell out too. By the way, If you're looking for that spray, I think its by the pee pads and stuff at petsmart. Make sure you read the bottle before you buy it tho, there is another spray that makes them want to pee and poop in a specific spot to spray on the pads and stuff. Make sure you get the carpet/fabric neutralizer.
