Me and my four cats are excited, the rod rotates fast enough, making even more often a change of direction, it remains sometimes are and then continue again, very stimulating for the cats. I only found the bar a bit loose, I just fixed it with glue that holds. Just as a tip when he is on the carpet, he is quieter and the cats do not scare so the first time around. Conclusion, I can occupy myself with other things would be my four bespaßt ;-D
