My neighbors cats ruined my garden last year....it's a raised garden (about 4' from the ground because I have a hip problem). Spent a fortune on various products last year to deter them, but none worked. Cayenne pepper works until the first rain, and the same with Tiger powder. I also used moth balls, but I read those could be lethal to birds and pets as well. I'm preparing to plant soon, and welcome any advice you might have to keep my beautiful garden from turning into a giant litter box. Thank You.

It may require some fencing to keep them out. Pepper extract will work, especially hot sauce mixed in water, but it will have to be applied repeatedly. Here is an article that can help: https://www.gardeningknowhow.com/plant-problems/pests/animals/cat-repellent.htm
