simple to put together and its pretty solid. we have 3 cats, 2 less than a year old and full of energy and mischief. they especially love it. our older cat is almost 12 and she likes it too. the perches are of good size and the boxes are great fun for the cats to hide or sleep in the hanging toys are a good idea, yes our cats destroyed them but we easily replaced and added more.
we cant and i'm sure our cats wouldnt find fault with this cat tree. we looked n local stores (in saskatoon) for similar products but most were double the price and half the quality. if you want complete catisfaction... this is the one we would suggest.
