It works
I read all of the reviews before I bought it out of desperation. We have feral cats that come onto our front and back patios.  This spray works but you have to spray every other day if not every day.  I read that these cats are hard to break so I have been very consistent using it.  It stinks and is the color of urine. The smell dissipates so we’re able to handle it.  I spray around the perimeter of the area I’m trying to keep them out of. The cats were getting on our outdoor furniture cushions.  I put an old sheet/towel over each cushion and spray that.  I just bought another bottle.  Although it is keeping them away, I’m really hoping I don’t have to do this forever and that the cats will move on stop coming.
