Organic Cat Repellant

To keep cats from using your mulched flower bed as a litter box, use peelings from citrus fruit.  Spread orange, lemon or lime rinds around your garden to deter cats from using it as a public toilet.  If you want to take it a step further, buy a citrus tree and plant it in your yard.  You can save money by growing your own citrus fruit and use the rinds for compost and repellant.
