Worked for my cats. It's like the scary boogy man. They give it the weary eye and keep 15 feet away. It only took one time to teach them it's a no no.
Disappointed now by Chris03/19/2013
Because we have a really hard time at getting the top sprayer unit over the refill air container I'm not very happy about your product now. When we took the top unit off to replace a new refill can we discovered one of the black teeth got broken off first time. We ruined a whole can of air trying to get it on. We had ordered 2 cans so tried 2nd one and could only get it on part way so it doesn't work that well. We follow directions how to get the spray unit on air can but it takes more muscle than we have. Is there an easy way?? The product really works well but now spray unit is ruined as it cracked the round ring which locks it in place.
