My cat didn't climb high, so I only set up the cat tree for scratching, and she didn't use the tower. I was only using the bottom support pole, swapping it with the upper support pole. *Support poles and the transparent spaceship are not included. If you need the used support poles, please consult with me before purchasing in the comments. (Because the shipping size will change) If the support poles are included, the shipping cost will be added, so I'm afraid I'll have to sell it for 4,250 yen. Thank you. I've added photos of the support poles (7, 8, and 9).
