Excellent for large cats!  I have 3 male cats, 2 are very large, 15 lbs and 14 lbs who have destroyed many a cat treecondo due to their sheer sizepower.  I needed a tree that was made of wood to survive my cats, and I have found it.  Ive had it for about 3 weeks now, and they absolutely love it.  Very sturdy!  It is easily holding up to their playfulness!  They love it for naps too!
