The other morning, my long haired cat threw up on our t.v. room couch. No big deal really, I thought. However upon closer inspection, it was runny and no solids, so out came the shampooer and me off to do my wonderful cat owning duties of cleaning up after the little hairball. Anyway, now after shampooing the couch TWICE, there is still an odor. Normally, I don't smell anything, but it's so strong that it smells like human vomit. Seriously. And I can't seem to get rid of the smell. I'm ready to throw my couch out and light it on fire. I seem to smell it throughout the house, but I have an incredibly sensitive nose. I think it's horrible and DH can only smell it if he's in that room...not good enough for me!! I don't want to smell it at all!! Any suggestions as to how to get rid of this will be tried and greatly appreciated!!
