The carpet on this scratcher does not hold up. My cats almost immediately started pulling chunks of carpet out. Just 3 months later the carpet has been completely shredded and scattered around my apartment. The mess is never ending. Every time I vacuum up carpet shreds more appear. It's a shame since it is the perfect height and shape for what I need. 

Also, since the base is round it easily falls over. It's small enough that it's no big deal, but I'm sure my downstairs neighbors are not fans.
