This is a slim, space-saving cat walk. I bought it about 7-8 years ago. I had it set up for the first year or so, but my cat didn't use it much, so I ended up putting it away and storing it at home. It shows some signs of use, but I think it's still usable without any problems. All the parts are included. There's also the instruction manual. From the website: * Easy to assemble, just join and screw together. It doesn't take up much space due to its shallow depth. * You can attach the shelves and hammock to any position you like, up, down, left, or right. * The height from the floor to the ceiling can be adjusted from 228cm to 273cm. * Please make sure to check the height of your ceiling before purchasing. #catwalk #cattower #cattree
