Query: Cat owners beware!

I gave this a 2 star only because something in the smell of it made my cat go absolutely crazy! I put the gel on my foot and wore my shoes; later in the day when the shoes were off and the cat caught whiff of them she went ballistic...like she had been given an over dose of catnip or mind altering drug!! She attacked and played with the shoes and then was ready to start at my feet. There must be some ingredient in it that stimulates the cat's brain. I had to give my 2 units to a friend who has no cats and he says that the product does provide relief so maybe my rating would have been higher had I been able to use it.
