This is a tension-pole cat tree featuring a red platform. - Brand: CattyMan - Model Name: Neko Ring Catty Ball Hammock - Color: Red - Type: Tension-pole cat tree - Height: Adjustable Thank you for viewing. I purchased this on Amazon around 2020 for just over 20,000 yen. The current style seems to include a hemispherical bowl (see photo), but at the time of purchase, it only had the red steps. I believe it came with a set of 4 steps. I used this when I left my cat at my parents' house (the cat never climbed on it, but did climb the adjacent two-pole tower, so I put food on the red steps). There is some dirt on the steps that cannot be completely removed even with wiping. I wiped the poles and removed as much hair as possible with a lint roller, but some may remain in the fibers, so please be aware of this.
