Best Cat Grass Kits and Seeds for Munching and Nibbling
Contents of Article
Just about every cat naturally munches on grass – but why do they do it?
I’ll just be upfront about it: humans don’t know why cats eat grass. Speculations abound, but there’s little consensus on the true reason why virtually all cats instinctively nibble on grass. Let’s go over some of the popular theories.
Because in so many cases, eating grass makes cats vomit, one theory is that this is exactly why they consume it – to help get rid of indigestible parts of prey or to get rid of hairballs. Similarly, the fiber content of grass could work as a digestive aid. Another theory is that cats eat grass as a mineral supplement. Grass also contains chlorophyll, which has multiple uses as a remedy for pain, infection, anemia, and skin disease. The folic acid in grass can help improve circulation.
Besides that, cats might just enjoy eating grass for fun. It has an interesting texture and flavor that might add a little variety and joy to their lives.
Without the ability to nibble on appropriate grass, outdoor cats may turn to chemically-treated grass and indoor cats may turn to toxic houseplants and flowers. Offering a planter of cat grass provides a healthy and safe outlet for these munching instincts.
What are the Best Cat Grass Kits and Seeds?
What is cat grass, anyway?
Cat grass is a straightforward product – it’s just a grass or blend of grasses that is safe for cats to eat. While oat grass is the true “cat grass”, other grasses like wheat, rye, and barley are also commonly used. Any grass marketed as a cat grass is appealing to kitty taste buds. For beginners, cat grass is available in kits that supply a planter, seeds, and soil, making it easy to get started growing cat grass inside of your home. With appropriate water and sunlight, the seeds will sprout in about 2-7 days. After a couple of weeks have passed, you’ll have a little grass garden for your cat to enjoy.
Choosing the Best Cat Grass
While each of these types of grass has a slightly different set of qualities and benefits, they’re all good choices. Some finicky cats will prefer different grasses to others, so it’s a good idea to try out different grasses and blends to find the type that your cat prefers.
Oat
Oat grass is the true cat grass – a package of seeds labeled just “cat grass” typically contains oat seeds. It is a slightly sweeter-tasting grass than the others listed here, making it appealing to finicky feline tastes.
Wheat
Containing 70% chlorophyll and packed with minerals, wheatgrass is a popular addition to the diet of health-conscious humans for the same reasons why it’s a good addition to your cat’s. It can help to fight inflammation and improve immune health.
Rye
Ryegrass is a shorter, more durable grass, meaning that it can easily spring back after your cat rolls in it.
Barley
This tall grass reaches up to 14” high and grows quickly, making it a great choice for the most voracious nibblers.
Look for organic seeds.
They’re harvested from plants grown without chemical pesticides, herbicides, and fertilizers, making them safe a safe choice for your cat.
Choosing the Right Kit
If you choose to use a cat grass kit, you’ll find that they come in shapes and styles to suit different preferences and living conditions. Some feature organic potting soil and seeds, while others don’t. Keep location in mind when choosing your planter or kit. Whether you place your cat’s garden on a catio or a large windowsill, it’s important that it is the right size and shape.

How to Grow Cat Grass
Whether you choose a cat grass kit or are using a variety of your own supplies, growing cat grass is simple, even for inexperienced gardeners. Here’s how to get your kitty garden growing.
Plant the Grass
In an indoor planter…
It’s not necessary for your planter to have drainage holes, but if you prefer, you can use a planter with holes in the bottom and a tray underneath to catch water as it drains. Doing so prevents nutrient loss from excess water and keeps the roots healthy.
Fill your planter with potting soil until there is only about 1-2” of space between the surface of the soil and the top edge of the planter. Sprinkle the seeds over the surface of the soil, then cover with ¼” of additional soil. Add enough water to dampen the soil. After planting, you may lightly cover the planter with plastic wrap and leave it in a dark, warm place. Ideally, the planter should be kept at about 70°F. Monitor the planter to ensure that the soil remains moist. In 3-7 days, you should see the first sprouts emerging from the surface. Once the seedlings are about an inch tall, remove the plastic wrap and transfer it to a sunny location. It’s best to choose a location that’s safe from your curious cat. You’ll want to wait another week or two for the grass to reach about 4-6” in height before you let your cat discover it.
In the earth outdoors…
Sow the seeds in the spring after all danger of frost has passed. Clear out any weeds or other plant matter from the area where you intend to plant the cat grass, then smooth out the area. Sow the seeds ¼” deep in rows that are 1” apart. Lightly tamp down the soil over the seeds, then moisten the soil. Keep it evenly moist at all times. The seedlings should emerge in about 3-7 days.
Maintenance and Tips
Once your cat grass garden has gotten going, here are some tips to help it flourish:
- Water the cat grass gently with a spray bottle as soon as the surface soil dries.
- Trim the grass back regularly to encourage fresh growth.
- When the grass goes yellow, replace it with new seeds. This usually happens after about 2-3 weeks, although some grasses last considerably longer.
- Immature grass is best for cats – mature grass is rough and can be dangerous for your cat to eat.
- Rotate multiple planters of cat grass so that your cat always has a fresh supply.
Letting Your Cat Eat the Grass
This one is pretty simple – place the planter in one of your cat’s favorite sunny spots and let them discover the fresh greens. If you grow the cat grass in an outdoor garden, the principle is the same – just wait for your cat to discover their special grass patch. Of course, not every cat will be attracted to every variety of cat grass, so it may take a few tries before you find the grass that’s perfect for your cat. In all likelihood, however, it won’t be long before you find your cat nibbling at the grass appreciatively.
