When Coffee Smells Like Cat Piss

Suz's post about coofy got me to wondering why Italian roast smells like cat piss to me. And another thing that smells like cat piss is the milk section at the local HEB. When I open the door to get my milk, the odor is incredibly strong. So I wonder if they put cats in there to get the mice or do they spray cat piss to keep the mice away?
