Query: Did not like this item

I purchased this item after my litermaid auto box expired. I ended up going out and buying the litermaid box again. This box does not keep up enough with multiple cats, when a cat had a bowel movement I could smell it through out the house. The cost of upkeep was too high. I was buying a refill box every week, that was running me $80 a month to upkeep.
