Cat loves this.  I like it, but it does require vacuuming the area at least once a week.  Also,  once the cat destroys enough of one side of the triangle, there are 2 more sides that can be used.  It won't have a long life span though, so because of that, and the cleanup - am giving only 3 stars.  The cleanup and limited usage are not a surprise - I bought it in spite of knowing that.  I do like the design and it doesn't take up much room.  I also got this on sale (half-price) which also made it much easier to decide to purchase.  For the time I'll have it,  it will work just fine.  The cat also likes to sleep inside the triangle area.  Which makes it more than cute.
