Cat Grass Seeds: Trial Set of 6 Varieties @ Anonymous Delivery A small amount of seeds for 6 types of cat grass (Poaceae family). Please try this if your cat doesn't eat commercially available cat grass (such as oats, barley, or Italian ryegrass) or isn't very interested in it. Unlike oats, which sprout and grow within a few days of sowing, these varieties may take 10 days to several months to germinate. (Among them, foxtail millet seeds have very strong dormancy, so please be patient after sowing.) (Not suitable for hydroponic cultivation.) * Golden Foxtail (Setaria genus) * Crabgrass * Barnyard Millet * Foxtail Millet (related to foxtail millet) * Proso Millet * Foxtail Millet
