I am always looking for scratching stuff for my precious little kitties.  This was pretty cheap, and I have several bigger cats, so I like them to be able to stretch out when they scratch.  I have to say, this vertical scratcher is awesome!  I sprinkled some cat nip on it once I had assembled it (which was stupid easy by the way!) to get the kitties going with it, and they LOVE it.  I might have to purchase another one, since I thought it was such a good deal, and I am very impressed with the construction!
