Pet QwerksX-Tire Ball Dog Toys - Animal Sound Interactive Chew Toy - Small

Is this a rubber ball? I had bad experiences with heavy HARD not bouncing "ball" that can hit the head of the dog and possibly injure your dog.

Is the noise level modifiable? My blind dog must have really heightened sense of hearing and does not like loud noises.

How do you open the ball to replace batteries without tearing it up?

I finally managed to get the two screws out but I can't seem to remove the slotted battery cover - how do you remove the slotted cover: does it turn?
