Listing details to confirm
The stated 20–30-day duration is a manufacturer claim for one cat and can vary with diet, age and health. The listing also describes use as up to 30 days, so treat this as an estimate rather than a guaranteed interval. The listing claims low-tracking and dust-free performance, including a 99% dust-free figure, but these are manufacturer claims rather than independently verified measurements.
