We spend a lot of time talking about the plants cats shouldn’t eat (tiger lilies, day lilies, and Easter lilies, for starters — lilies are bad, mmmkay?), but what about the greens that are nice for a nibble?

Kitties are obligate carnivores, meaning they require a diet of meat, meat, and more meat — so plants are just a fun, nutritionally void snack, kind of like that last box of Girl Scout cookies in your kitchen. It’s also possible that cats nibble on grass to help clear their digestive tracts of hairballs and other detritus — in other words, so they can barf it right back up.

My cat Bubba Lee Kinsey nibbles on some cat grass.

Fortunately there are several feline-friendly plants you can grow at home on your patio garden, satisfying your human need to be surrounded by colorful living things while simultaneously ensuring kitty will be safe if she decides to make your window box into a breakfast buffet.

1. Catnip

It’s super cheap and easy to grow catnip at home. All you need is a packet of seeds and a pot of soil, and before you know it your happy kitty will be able to get as stoned as her little heart desires. Catnip requires full sunlight, so you may need to keep it outdoors — and, naturally, out of reach of other neighborhood wanderers who might want a taste. Growing it in a container might be preferable, because this member of the mint family can be invasive.

2. Oat grass

Oat grass, typically marketed as “cat grass,” is fun and easy to grow. Simply plant the seeds in a pot (any size will do), and within a couple of weeks you’ll have a thick, luscious patch of greenery for kitty to enjoy. I typically leave the grass outside and bring it in every couple of days for Bubba Lee Kinsey and Phoenix to munch on. I do keep an eye on them, though, or they’ll eat the whole thing.

3. Bean sprouts

These earthy little bits of roughage quickly add texture and crunch to any salad or sandwich — and in small amounts, they’re harmless to cats. If you want to hone your green thumb but know your kitty will devour anything you manage to grow, sprouts are a great way to get your fix and ensure your feline friend stays safe.

4. Herbs

In addition to bean sprouts, various herbs are also harmless to cats (in small quantities, of course; remember that cats are mad about meat, so plants are not a vital component of their diet). Valerian root, known for inducing sleep in humans, has the opposite effect on cats, causing your lazy kitty to get up and go (but it kind of smells like a foot). Many common herbs used for seasoning are also cat-safe, including basil, dill, lavender, mint, oregano, parsley, and rosemary.

Given the choice between herbs and grass, however, cats are more likely to choose grass, so keeping them side by side may discourage kitty from destroying your dinner plans.

5. Edible flowers

It might seem no bouquet is safe from your cats, but certain flowers are safe for your cats. Some options include roses, zinnias, gerber daisies, sunflowers, roses, and snapdragons. Bad news: The cat in the photo above wants to eat that tulip, but these early spring bloomers are potentially toxic! So are carnations, daffodils, and — you guessed it — lilies.
