Growing cat grass is super simple! I grow it all the time for Big Dee and Lu. All you need are some cat grass seeds (easily found in most pet stores or online!), a small container for growing in and some soil.
Fill the container most of the way up with soil – leave a couple inches at the top. Then sprinkle the soil with an even layer of seeds. Cover the seeds with about 1/4 inch of soil.
Now you’ll want to water it lightly and cover it with a little plastic wrap. Place it somewhere dark for a couple days. In 2-3 days you’ll see sprouts! At this point, take the plastic wrap off and set the grass in a nice sunny spot for 3-4 more days. Keep it away from the kitties! They tend to destroy it in two seconds at this stage. 😀
I like to let mine grow to 4-5 inches before I let them at it – it stays alive a little longer that way. It doesn’t need much care, just a little water whenever it gets droopy. It will only live for 2-3 weeks in most cases. Especially if your cats are big grass eaters like mine are.
