There's no proof that grass is essential or helpful to cats' diets, but by offering them their own "gardens" to dine on, they'll be less likely to eat your other houseplants. Place catgrass in a sunny windowsill and water it whenever it begins to dry out. Catgrass will re-sprout after being chewed on. Keep several pots on hand so as one gets nibbled down, you can offer another. Genus Name Avena sativa Common Name Catgrass Plant Type Annual Light Sun Height 6 to 6 inches Width null to 9 inches Special Features Good for Containers, Low Maintenance Zones 10, 2, 3, 4, 5, 6, 7, 8, 9 Propagation Seed Find more about choosing and growing annuals.
