I have absolutely no idea, but they are not poisonous to cats. If you want cats to keep away from your garden, there isn't really any way to keep them out. However, you could put a motion-activated noise maker, also used to keep raccoons out of garbage cans. It will make a loud noise, such as an owl hooting and swooping down, a wolf's howl, or a dog barking. If your cat hears these things so close, I'll tell you she'll probably run like h*ll.
The best plant is Rue, the herb of grace, I think it is ruta graevolens.
Red pepper should not harm plants in your garden if you sprinkle it around the plants to keep the cats and dogs away. However I would keep it away from the leaves and petals.
There are sprays available at any pet store that you can use in your yard to discourage cats from wandering in your yard.
You should not use Clorox or any type of bleach to keep cats away. Clorox and bleach are poisonous and can kill the cats.
i would say so. i have 3 cats, but im not gonna try that on them.
