Pros: tall; durable; good quality
Many scratching posts are simply too small for a full-grown adult cat. This one is about 32 inches high, which allows for our two kitties to get a good back stretch.
The scratching post is also very durable and has a wide, stable base. It is covered in sisal rather than carpet, which I like -- I don't want to train the kitties to scratch our carpeted floors!
We've had the scratching post for almost a year now (we had to donate our old one when we moved from the U.S. West Coast to the East Coast... it was cheaper to replace it than to ship it), and it's holding up great. We are sure it will last at least several years. :)
