i bought this for my three kittens and they are obsessed with the scratching boards already but my god the box was so heavy when it arrived i had to drag it across the floor and scratched the wood a bit… my fault i guess but just be warned its big. the top beds are soft and the hammock is their favorite spot to sleep. gave it 4 stars just cuz assembly took me like an hour and a half and my back hurts now.
