This is better at keeping me away from an area then my cats. To me it Stinks my brother can't smell anything and I think neither can my cat because after spraying an area to where its soaked couple of hours later he's there going no 2 again. I have used up 75% of the can in a few days and it has don't nothing to train the cat. What a waste of money.
