Australian-grown Oats Oatmeal Cat grass seeds These oats were originally pet food and are not seeds for sowing. However, even I, a gardening novice, can easily get them to sprout and grow lushly like in the photos. I've received questions about the germination rate, but I'm sorry, I don't know. If you spread the seeds to cover the surface of the soil, they will become as fluffy as the cat grass sold in stores. After putting the seeds on the soil and watering them, lightly pressing the soil is said to help the water circulate and promote good germination. It is said that it is easier for the seeds to sprout if you don't let them dry out once they get wet.
