Petio Cat System Toilet (Compatible with clumping cat litter such as wooden pellets)

Thank you for looking.
This is a Petio system toilet for cats.

It was used for about 3 years as one of three toilets for two cats. I am selling it because I have switched to an automatic toilet.

I used a type of wooden pellet that crumbles and falls. I have tried various cat litters, but I find wooden pellets to be the most effective for odor control. I also think the economical aspect of not needing to use sheets is a good point of this product.
(Of course, I believe it can also be used with a combination of water-repellent sand like Deotoilet and sheets.)

There are signs of use, but no major scratches or cracks, so I believe it can still be used.
I have cleaned it with detergent and Gekiochikun (a cleaning sponge), but please refrain from purchasing if you are sensitive.

Immediate purchase is welcome.

Thank you for your consideration.
