What is Cat Grass?

Cat grass is what we call grass that is grown for cats to enjoy. Cat grass could be from wheat, oats, rye, or other grasses. Sow Right Seeds cat grass is from 100% oat seed. We chose this as our go-to cat grass because we found cats enjoy the sweet taste, and it’s easy to grow.

Why Do Cats Eat Grass?

Your cat can’t tell you exactly why they enjoy cat grass so much, but there are some theories as to why you’ll find these little carnivores munching like cows.

Benefits of Cat Grass

1 - Fiber         

Cat grass can provide fiber. While cats don’t need a lot of fiber, it can help move things along in their digestive tract. Cat grass can also act as a laxative and help push out hairballs.


2 - Vitamins        

Some vitamins found in cat grass are folic acid, vitamin A and vitamin D. Folic acid is an essential vitamin for cats that helps with digestion and cell growth. Vitamin D is needed to help the body absorb calcium. Unlike humans, cats don’t convert sunshine into vitamin D so they need it in their food. 


3 - Chlorophyll        

The bright green chlorophyll in cat grass can help their breath smell better.


4 - Mental stimulation        

Cats are naturally curious. They love sniffing new things and finding fun ways to interact with their world. The smell and look of grass is interesting to them, and they will want to explore. Munching on grass is different from a bowl of dry kibble. And it can be entertaining for them to tear and pull at as well. And who knows, they may even hide behind it to stalk their prey.


5 - Tasty Treat        

As a carnivore, cats don’t need grass to survive, especially when they are fed well-balanced cat food. But the sweet taste of oat grass is a change of pace from the flavors of cat food. It’s a healthy treat they enjoy and that you don’t have to worry about.

How to Grow Cat Grass From Seeds

Choose a container

      The container will need to hold a minimum of 1” of potting soil and has holes in the bottom for water to drain. You will also want something that won’t tip over easily. While some cats will gently munch on blades of grass, others will pull and can make a mess if the container falls over.


Add Soil

        Put enough potting soil in the container to hold the roots. A minimum of 1 inch is recommended. 


Sow Seeds

        Sprinkle the soil with cat grass seeds and cover the seeds with 1/4” of potting soil.


Water cat grass

        Soak the seeds thoroughly with water and keep them moist until they start to sprout. Generally, in 5 to 7 days.


Provide Sunlight

        Keep the container in a bright room. Cat grass needs light to grow, but it doesn’t require direct sunlight. 


Harvesting Cat Grass

Once the grass is about 4” tall, is it mature enough for your cat to start eating it. 


Place the container where your cats can get to it, but apart from other houseplants, so they will know the grass is for eating when the other plants aren’t safe for nibbling.

When the cat grass starts changing color or dying off, it’s time to plant a new batch of seeds.
