Why do cats like Organic Cat Grass? More and more cats live exclusively indoors where they must depend on their owners to provide the safe and healthy plants that their bodies crave. Our organic seed products can help by, provide cats with essential vitamins and folic acids, aid cat digestion by adding roughage to their diet, assist in removing hairballs, keep cats away from hazardous houseplants and satisfy the natural cravings that cats have for grass! Sow seeds on top of a light soil mix, barley cover with soil. Soon tiny sprouts appear. Keep your cats away from the grass until it has grown about 6 inches high. Stand back! Cats love this stuff!
