To relieve your beloved cat's lack of exercise and stress! A running machine for cats. Recommended for indoor cats to alleviate lack of exercise and release stress. The main body of the wheel is a cardboard scratching post, so your cat can scratch both inside and outside the wheel (replacement scratching posts are sold separately). It can be fixed to prevent it from turning when needed, such as at night or when you go out, so it can also be used as a cat tower. The rotating sound is quiet, so it can be used in apartment buildings. 《Product Specifications》 ●Size Overall: Approximately W610 x D390 x H665mm Ring only: Width 31cm, Diameter 59cm ●Material/Material: Base/Outer frame of rotating part: MDF / Main body of rotating part: Cardboard ●Weight capacity: 15kg The cardboard scratching post has signs of use (Photos 7 & 8) It's only a little, so it can still be used with confidence.
