I've only actually used it for about 3 days since I bought it. I used to have one before, so I chose this one, but I think I made my cat feel stressed because I changed the type of sand at that time, so it didn't use it, and I was thinking of listing it on Mercari soon m(_ _)m After washing it and drying it outside for a few days, I stored it, but I threw one away as bulky waste. I also have another type of cat toilet, which I also cleaned and stored, and it's the same white Nyan-tomo series? It's for the Hinoki sand type? and also for the toilet sheet type. I plan to list it soon m(_ _)m I would be happy if you would take a look at that one too. ⭐︎For more details, please see the Amazon listing where I purchased it m(_ _)m Instant purchase available ~ It's big, so I can't lower the price, but please check the profile for follow-up discounts, etc.
