My plants are growing!

I am so excited; the tomotoes and peppers that I planted in pots are growing. The flowers at the front of my house are growing as well, although not as well as the vegetables. I recently discovered that the neighborhood cat has been using my flowerbed as a bathroom. Does anyone have any suggestions on how to stop this? I once heard that spreading chili powder by the flowers would stop a cat. Is that true? Anyway, here is a picture of my potted plants. Thanks to Mom and Dad for teaching me how to garden. Now I just have to wait for them to sprout something edible.
