Sprout People. 2. Lemongrass (cymbopagon) - Kitties love the smell of lemongrass, so if you're growing some for yourself, grow some extra for them to gnaw on. 3. Catnip (nepeta cataria) - As seen in the photo below, some kitties will go absolutely crazy for this stuff. Caution: it will also attract neighborhood cats. So if you don't want it all steamrolled by chemically altered felines, you might want to grow some of it in a hanging basket. I learned this the hard way when I found all the catnip in my garden completely flattened. At least some kitties had a good time! 4. Catmint (nepeta x faassenii) - Gorgeous plant with purple blooms, attracts not only cats, but butterflies and bees, as well! 5. Mint family - Cats can be attracted to mint, while mice are deterred by peppermint. So, if you want to make your furry friends happy and lessen your chance of having a mousy gift left on your front doorstep, peppermint might be just the ticket. 6. Valerian (valeriana officinalis, valerianaceae) - Has a similar effect as catnip and is a mild stimulant. Commonly has white or pink flowers.
