I bought this on Amazon for 50,000 yen. I bought another one when I got another cat, but then realized I didn't need two, so I'm selling this one. It's managed by smartphone, has a sensor, and has been fully tested and confirmed to be working. It has been cleaned with LION disinfectant cleaner, but there may still be some residual smell and signs of use. ^ ^ The anti-slip mat is included, but it's dirty, so I recommend replacing it. It's large, so I may not have a suitable box. I will do my best to package it for shipping.
