If you'll excuse the mixed metaphor: we've got bigger fish to fry.
Olfactory evidence and the odd stray at the door suggests our new rental in Berkeley recently functioned as a commune... of the feline sort.
In other words, it reeks of cat pee. Yuck.
We're dousing everything with Nature's Miracle, which seems to be doing the trick, but it seems every time we find a corner the smell awaits. It even stinks behind the fridge. Yuck, yuck, yuck.
What's the answer? We're just about to buy the black light mentioned in the comments to the post above. If that doesn't work, it's on to Plan B: incineration. Not very green, we know, but at least the smell would be gone.
All kidding aside: has anyone found a green way to deal with this problem?
