Property already some Kratzbaeume assembled-it has a stable state, the boards are very stable running;, connecting bolts are sufficient the connecting bolts are screwed into a threaded one which turned into plastic one is-this creates a stable connection, which is not so slightly loosen. I am happy! Spare was replenished without problems - highly recommended!
Addendum: In December 2013, said Scratching, where the upper slopes deck mounted broken again! My cat has crashed again from the top level, was very verstört- is nothing happens- twice I can not recommend this cat tree-see report "Tina" .... I have therefore changed my rating from five to one star.
