As a crazy cat lady, I several litter boxes in my house -- four to be exact. Two of them are in the kitchen, while the others reside in my bedroom. There is nothing worse than coming home after a long day at the office, only to be greeted by the foul aroma of a freshly used litter pan as soon as you open the front door. What can you do to keep your home smelling rosy when your cat's potty isn't so fresh?
