I chose this cat tree, because it suits heavy cats, it has many different types of shelves and it doesn't attached to the wall or ceiling (I'm living in the rental apartment and it's important not to damage walls/ceiling).
And it was the best choice!
Cat loves it so much. Now he spends most of his time there: playing, sleeping and looking in the window.
And quality of this thing is super! It doesn't wobble, when cat is jumping. Assembling seems to be reliable.
Highly recommended!
