If you love greenery and cats, you're eventually going to find your favorite potted plant with missing or gnawed leaves. Many houseplants are toxic to cats — a number of the most popular plants (lilies, azaleas, pothos, and more) can be as deadly to your kitten as a sip of antifreeze. The National Animal Poison Control offers a complete list of cat-safe plants.

Many animal behaviorists believe the best way to protect both your kitten and your houseplants is to give kitty a little garden all his own. You can plant a cat garden in just seconds, using kits available from any pet retailer. Even if you have only a marginally green thumb, you can grow greenery that your cat can safely munch on. Cat grass kits come in a variety of forms, from ready-to-munch sprouts to a bag of seeds. Cats can safely eat wheat grass, barley grass, oat grass, rye grass, bluegrass, and, of course, catnip. Plant the seeds in potting mix that you buy in bags; don't use the soil from your outdoor garden. Your parasite-free kitten could get worms from neighborhood cats who have pooped in your yard.
