Fill a squirt bottle with water and add a few drops of cinnamon oil or ground red pepper...shake well and spritz down the plants. This usually works with my cats. (and it won't hurt them)
I took those aluminum things that go under your burners, cut a slit from the edge to the hole, and put it around the base of the pot. Keeps cats out, but allows easy access for watering.
Use vinegar. Lol, i know it sounds funny but cats hate the smell. You just put like a small bowl of it in your plants (dont pour it in, just leave it there) and your kitten will hate the smell of it. After a while, she'll know not to go there.
Cut pieces of chicken wire or door screen to fit around your plants. If that doesn't work, they sell plastic disks with spines on them to keep cats out of your plants.
Put tin foil around base of plant.Do not let her eat the leaves of any plants .Many are toxic.Put plants up where she cannot get to them.Thats how I cured my cat.
