For thick cat this cat tree is safe to recommend less. Even my cat has with its 5 kg no chance to lie down in the hammock or sit in the cave. These two places are however used with us anyway only for toys. The top deck area I had to replace unfortunately, otherwise it will not be there could be. It is a pity that the original really was very small. The tree will vary even if he jumps up; but for the price I do not expect that the scratching post is about the next 10 years.
