Received within 3 days, this cat tree is beautiful invoice. It has many platforms covered with sweet little toupee. It is high enough (1m40) to allow my cat to observe the surroundings. It seems stable. The leaves of water hyacinth making up the various platforms and niches are attractive. This is a shaft that can blend in with its environment unlike most other trees which are not very "class". One of the platforms gave me a little trouble to screw the little beam of sisal, but I disassembled and rebuilt at the base installation and after it went well. You can climb it alone with a little elbow grease (and a bit of force) to screw the small beams of sisal. The "key screwdriver" comes with screws, no tools required, it is convenient :) I did that for now so I can not speak to the strength of the product but I am hopeful that it fits well.
