I wouldn't use febreeze if the odor is that bad.  Febreeze seems to be a short term solution and later on the smell comes back.  I tried it once on some heavy duty jackets that were delivered to me from the customer that smelled like a dead mouse had been in there and it worked for a couple days and then the odor just seemed to come back.  It really was there issue in the end to get it cleaned professionally but I just wanted to get them so I could have it smell ok until production was done.
