Thank you for viewing. Unfortunately, it seems this didn't suit my cat, so I'm putting it up for sale. I used it for about a month, so there's some wear and tear, but I think it's in good condition. I used one of the three included separate-sale filters, so I'm including the remaining two. *Regarding the filters, I will remove them from their outer box and include only the filters when shipping. I am looking forward to purchases from those who understand that this is a used item. I will ship the main unit in its original box, and then in a cardboard box.
