I thought that cat of corruption would be effective in that it leaves the quiet furniture! This tree is not heavy enough to fall on him when he made his claws! This he did abandon the old. The bases are very good for observation, but a little small for sieste.La hiding on the ground, and nap not possible either, she likes the pitch. But overall it is a good compromise, my cat discovered it yet, but she seems to love. To follow, but I hope it will be better than the sofa object of his attentions today!
