OK, here is my situation. I live in a condo, 1 floor and we also have a townhouse above us. There is an awful foul smell coming from our kitchen. At first we thought it was garbage accidentally thrown in the trash can. But it is not. It seems to be coming from under the cabinets next to the refrigerator. The problem is I can not pinpoint where it is coming from. Any ideas would be really helpful.

Looked and cleaned the refrigerator, did not look behind it yet, and also cleaned out the cabinets under where it seems to smell the worst. Nothing has helped yet. Thanks in advance to any suggestions.

Are there any gaps in the cabinets where mice could get under them? Could be something died under there?? I know that happened at one of my jobs.
