I have around my two indoor cats to me offer this product to located some variety. Of course, the toy is not necessarily quiet and perhaps not really suitable for jumpy or anxious cats, as in holding the rod, the device begins to rattle a little louder. Otherwise, the toy seems to really be fun. My two love to hunt the bar afterwards, to stalk and to jump. The bar is flexible and dissolves in strong pressure, which is in my opinion necessary to prevent injury to the cat. The only drawback I could find so far is that the battery compartment cover. This can be since the second time unfortunately Change batteries no longer screw on, but probably is here rather the user the problem (a piece of duct tape cemented the matter successfully, without screw).
