We bought this cat tree to replace one that shed carpet fluff all over the house. Between normal deterioration and our cats' activity, the stuff was coming off in tufts nonstop. This carpet doesn't have quite as deep a pile, and while there are of course little bits of yarn that come off when the cats scratch it, it's only about 15% of what was coming off of our old one. Add to that that it has TWO of the highest level perches and two additional perches, and this is a purchase we are super happy about.
