Cats make a toilet in my flower box

I dug up all the cat crap from the flower beds, then filled a number of 500ml bottles of water apparently they don’t like the way the light reflects off it, then lots of end cuts from lemons, lime, and grapefruit spread around the beds, then covered with a net. I will take pictures tomorrow and post as I had to finish it off in the rain and hail this evening no time for photos, hopefully this will work
