Since barely tick in the fur and no ticks which have sucked themselves. Since the effectiveness of the long-term test was very good, I can recommend this product. Since I live in the forest, the ticks density is very high, therefore I am now completely satisfied!
The reflective strip at night when lit by lamps or car headlights, highly visible - at least for short-haired cats (therefore the right one for my little black cat ...) - naturally poorer in longhairs visibility.
