Query: Green slimcat feeder balls

I got this ball to slow down my male cat's inhaling of his food. It definitely does that! I recently switched my cats to an all canned food diet though, but these feeder balls do help if you feed your cat dry food. Two of my cats had these and while they didn't get any exercise using them because they would just tap it or nudge it with their noses to move it enough for food to fall out, it did the job of slowing the eating down.
