The next time prefer another product ...

- The top plate is completely missing (actually that would be a reason for the return!)

- Fixing on the ceiling would indeed work in principle, but unfortunately seems to be the thread not exactly 1: 1 with the
Screw match - indeed> it spans but still wiggles in all directions: Heavy cats are upset the scratching post here: P

- The contained to instructions fixing parts (wing nut, nut, etc ..) not correspond to what you get.

Two pluses I give anyway:

+ It is relatively cheap (but this one also has problems: P)

+ He is to save space (narrow) but still high ceiling (unless you find a way to strengthen the poor ceiling attachment, otherwise it will topple over sooner or later !!: D)

Conclusion:

Normally, I would pack up the cat tree again and send it back, but I need a space-saving and dispose of the tools to stabilize him I will
keep the cat tree and try the ceiling attachment reinforce, for the lack of drive I have a cubicle concerned in the local pet store and used instead.
I would buy anyone know about this product because it simply can not be that parts such as a lying area missing !!!
