Far-Infrared Cat's Soothing Kotatsu M Size

Purchased early in September 2025, I took it out around November. However, my cat only uses their favorite bed and has only passed by this one 2-3 times.
The futon has been washed.
Items will be shipped individually wrapped in bubble wrap, and the box will also be wrapped in bubble wrap.
