I was initially dubious about purchasing this cat tree, my cat doing 90cm 7.5kg I told myself that he rather not go into that box ... Lexpédition was very quick and satisfying With the arrival of the package I rode without any problem, it was even simpler. Once established, my two cats have loved directly and since they do leave more;) (this is only 2 months, to see even the stamina but he holds) I recommend it for all cats, including huge!
