After a post he has completely unraveled, my cat has taken over the energy with this new post. The rope seems more fragile than the original, but so far, despite its daily assaults seems sisal resist. To see in time, but after a use of more than one month, no signs of premature deterioration especially that this "little beast" is around 6.5 kg and has a phenomenal power. I give 5 stars without hesitation and to Amazon for meeting deadlines.
