Someone else offered spraying lemon juice near the flowers.
“I spray a lemon sprit on things I don’t want my cats touching or lying on. Also it’s not just unpleasant, their urine kills pretty flowers, my roses lost the will to live when my female kept wetting their flowerbed so had to use lemon peel there too.”
Someone tested the trick to see if cats actually hate the smell of lemon. They squirted some lemon juice on a bit of tuna that the cat normally loves, and it refused to eat it.
The user wrote: “They gave us a face that asked us why we would ruin excellent fish.”
