Is this the worst kitchen you’ve ever seen? Well, it may not look like it. But behind its benign, if somewhat bland, appearance lurked a dirty secret… a really dirty one. Mouse poop. Rob and Liz, the homeowners, were only using about 25% of their cabinet space, thanks to these uninvited guests. Additionally, the kitchen was freezing in the winter — standing in the right place, you could actually feel a breeze blowing across your feet. Lovely.
