We think the Kittyblock is the most sturdy and best scratcher we’ve ever bought. When Mickey starts to bite on it, (see top right corner) we can just turn it 90 degrees.
Here’s the KITTYBLOCK WEBSITE. I bought ours at www.fab.com where it was $10 less (limited time offer).
P.S. I should say that I bought this scratcher myself and have not been paid or asked to review it.
