Is this like canned air? If it is, I would be very hesitant to buy it. If somehow the can got knocked off a counter and the motion detecter went crazy, and kitty got too close, the air in canned air, if it is shaked or if the can is upsidedown, is like dry ice.. it can give the kitty frostbite. I use my canned air as a deterrent, but I don't shoot it at the cats, I shoot it over their heads.. it's the noise they hate, and I always make sure I'm holding the can steady and upright. I couldn't find if this is like the canned air we buy for computer dusting on the website though..
