Great for large cats!  A simple cat tree, not too high but with a large perch for our healthy sized boy!  He uses the scratch posts and occasionally plays with the ball hanging under the top tier (ours didnât come with a feather, but a plastic ball with a small bell inside).  I would recommend using a drop of crazy glue to secure the ball to the knot at the bottom.  We didnât at first and the string did come apart, but since adding a bit of glue, itâs held up well.
