I'm really disappointed in the quality of the cat tree.  My cats all have clipped nails yet the carpet material on the poles is coming out in "puffs" for lack of a better word.  They are floating around the house, get caught in their nails and I'm afraid they may ingest this material and get sick.  I'm going to have to cover the pole areas with roping and glue in place.
It's too bad because the size and look fit into our decor.  Something has to be done about the quality of material.  It's not worth $85.00.
