My whole downstairs smells like litterbox no matter how often I change it. I even deep cleaned the closet their boxes are in. Smelled the next day. It's embarrassing and damn those automatic litter boxes are expensive. I'm about to cave, though. I had a cat genie and I needed a part for it that I could not find anywhere. I called their customer service and they told me that they don't sell the parts for it anymore. I'm scared to spend that money on an expensive box if they can just force you to have to buy a new one in a few year because they discontinued the parts when it needs repaired.
