Speaking of pets.... cat food can go bad, and it will probably be the worst thing you've ever smelled. But once you've made sure thats in the far reaches of the county dump, beware of round 2 when the cats throw up said bad cat food. Not as bad smelling, but MUCH harder to find, clean, and neutralize.
have you tried uric acid? if it doesn't work at least ou mark your territory well!!! i think you should try and let us know how it went on your 1 thousand post
