Customers who touch Cat Seller often tell us it's "hard" and "sturdy."
The hardness and durability of this corrugated cardboard material are strongly related to how little debris it produces and how resistant it is to wear.

The corrugated cardboard used in Cat Seller is specially made in Japan for the purpose of a cat scratcher.
Most cat scratchers distributed in Japan are produced overseas, such as in China or Vietnam. These scratchers have a high recycled paper content, and their fibers break easily, leading to a lot of scratching debris. Furthermore, most Japanese-made scratchers distributed as "producing little debris" are repurposed standard corrugated cardboard used for cardboard boxes.
In other words, there are considerable differences even among products advertised as "producing little waste."
The selection of materials aiming for the maximum strength while maintaining a hardness that doesn't compromise the scratching comfort for cats is a feature of FURNYA's products, including Cat Seller.
There's much more we could say, but simply put, we, who are well-versed in corrugated cardboard, have "created cardboard specifically for cat scratchers."
We encourage you to feel for yourself how little debris it produces and how durable it is. If you have any questions, please feel free to contact us anytime via LINE, Instagram, or the inquiry form.
