Although you can buy wheatgrass, also called cat grass, at pet stores, it's much less expensive to grow your own -- and it's relatively easy to do. The growing process takes 6 to 9 days; the grass will last about a week. (If eating wheatgrass upsets your cat's stomach, discard the plant. If the wheatgrass looks unhealthy or shows signs of mold, it should not be consumed.)

Leafy Greens How-To
1. Presprout seeds: Soak seeds in cool water for 12 hours (soak enough to cover planter surface completely; seeds in planter should touch but not overlap). Drain seeds. Rinse in cool water, and drain again; set aside for 8 hours out of direct sunlight. Repeat rinsing up to 3 more times. The seeds are ready to be planted when a little white root just emerges.
2. Plant seeds: Sow seeds densely in 1 layer on moistened potting soil in planter. Cover planter with something that will block light but let air in (we used a shoebox lid). When pale sprouts are 1 inch tall, uncover and place planter in sunlight to grow. Water as needed to keep soil moist. Grass is ready when wider green leaves appear.
