Two of my 3 cats like the New Cat Condos Triple Cat Perch.  They ignore the bottom perch; they like the top two perches.  After a month of use, the carpet material is shedding pieces all over the floor and has bare spots and fiber sticking up.  This is my second disappointing condo from New Cat Condos.  The Cat Scratch and Lounge fell apart in the middle after about two months.  (I have photos.)  Unhappy with both these products -- a waste of money.
