We have two cats, which we wanted to break the habit of scratching at the doors. Logically, we beat no cats, but have served us the "Water tricks". :-) After a few days, the cats have learned that a targeted jet of water is not sooo comfortable. And this is precisely the strength of this spray ball: You can set a very fine mist, or a more or less sharp beam. The sprayer is processed valent, the nozzle is precise. He sits comfortably in the hand, -not only in Cat Education! ;-)
