Many cat owners struggle with keeping their cats from eating their houseplants. The instinct of cats is to nibble on grass, or anything green really, to supplement their diet with vital nutrients, aid in digestion, and reduce hairballs. Many cat owners may be tempted to let their cat go outside and eat grass from the yard, but many people treat their yards with chemicals and pesticides, which can make your cat ill or even kill it. The good news is you can grow your own grass for your cat right in your own home without pesticides or other chemicals. Whether you’re just looking for cat grass seed, or a full kit to get you started, we have reviews of the 10 Best Cat Grass Seeds and Kits in 2021 for you.
SmartCat Kitty’s Garden is our pick for the best overall cat grass. The seeds in this kit are a blend of wheat, oat, barley, and rye so your cat will get a nice variety in its diet. The kit comes with compact soil pellets that are placed in each compartment and filled with a few ounces of warm water. Once the water is absorbed by the soil, remove about a teaspoon of soil from each compartment, add the seeds, and then cover them back up. In a few days, you’ll see sprouts and before you know it, you’ll have a planter full of grass for your cat. This kit comes with a decorative wood box that is weighty enough to keep cats from knocking it over or pulling the cat grass out of the container. It’s important to remove any excess water from the bottom tray in the planter to prevent mold and fungal growth. Moisten the soil daily to keep the garden damp for optimum grass growth.

The seeds sprout within a few days, and you’ll soon have a container full of cat grass for your cat to munch on. The great thing about these seeds is that you get to pick the size of the container to grow the amount of grass you want for your cat. If you are planting a small container, you will get several yields out of this package, but if you are planning a larger planting, you may only get one crop if the container is a large one. If you only have one cat, you can plant a little at a time in a small container to save money by doing multiple plantings over time. If you’re new to growing cat grass, you’ll have to be careful to avoid overwatering or underwatering your grass.
The Cat Ladies Organic Pet Grass Grow Kit, 3 count, is the perfect cat grass grow kit for the very hungry feline. Cats that love grass are constantly munching away at plantings, often leaving pet owners with empty pots and very annoyed kitties complaining that their favorite treat is gone. This kit comes with three bags so you can start growing your bags a week or more apart, so you never run of out grass. Simply place the soil disc in the bottom of the bag, add water, sprinkle on the seeds, and grass will sprout within a few days. The GMO-free seeds are a blend of organic rye, oats, barley, wheat, and flaxseed so your cat has a choice of tasty grass blades to choose from when he’s hungry. The bags are tall, and your cat may have trouble eating the grass if you do not let it grow tall enough past the top edge of the bag. If you want shorter growth for your cat, transfer the soil and grass to a small pot for easy access before the blades get too tall. If your cat tends to carry things around that it finds interesting, you should transfer these bags to heavier containers, so you don’t wind up with dirt all over your home.
Easy to grow
Plantings can be spaced out so there’s always fresh grass
Tall bags prevent easy cat access

Owners with multiple cats should have plenty of seed to plant a large planter full of cat grass. Handy Pantry also offers a Cat Grass Seeds Blend comprised of oats, barley, rye, and wheat if your cat likes more than just wheatgrass to chew on. The company does have some cat grass kits if you’re a first-time planter and need some assistance in learning the cat grass ropes.
We included the Catit Senses 2.0 Cat Grass Planter on this list because it solves a problem many owners have with cat grass- their cats pull the grass out of its container and get dirt all over the house. This planter is designed to be low and features a deep planting bowl with a special grid cover to keep your cat from digging in the grass. The planter can’t be tipped over and it comes with vermiculate instead of soil to plant your seeds. The Catit Senses Cat Grass Planter does not normally come with seeds, but they can be purchased separately. The link we have provided includes the planter along with a three-pack of seeds. Do not overload the planter with seeds as they sprout quickly and too much seed will result in the grid cover being pushed off by the growing grass. Make sure to not overwater the grass so you don’t end up with root rot.
Stable design means no tipping
Grid cover keeps cats from digging
Seeds sold separately
Plant too many seeds and the grass pushed the grid cover off
Buyer’s Guide: Selecting The Best Cat Grass Seeds & Kits
What Is Cat Grass?
Cat grass is a variety of different grass seeds that you can grow indoors in a pot or other growing container to help satiate your cat’s need for greenery. The most popular grass for cats is wheatgrass, but you can also find oat, barley, rye, and flax seeds on their own or as blends. Some cats may prefer only one type of grass, but others may prefer a blend of the various types. It will likely take some trial and error when you first start growing cat grass to figure out what your cat likes to eat. We recommend starting with one of the smaller kits, so you don’t waste money on a large kit with grass your cat won’t eat. Once you have figured out what your furry feline likes best, you can then purchase seed or a larger kit to grow their new favorite treat.
What Are the Benefits of Cat Grass?
Cat grass is a supplemental treat added to cats’ diets to aid in digestion. Grass is a good source of fiber and adds roughage to their diet. It contains many beneficial vitamins and minerals, as well as chlorophyll which helps to replenish blood cells. It has the added benefit of reducing hairballs in cats and can even help to freshen your cat’s breath. Cats think of grass as a delicious treat and growing some in your home will help deter them from eating your houseplants, some of which can be toxic to cats.
How to Pick the Best Cat Grass Seeds & Kits
Cats love to chow down on some delicious cat grass, but there are a few things to consider before purchasing seed or a grass growing kit. There are several ways of growing cat grass.
Here are the options available:
Planting Kits – These kits usually come with seeds, soil, and a container to plant your grass in. They may come with a one-time-use container or with reusable planters.
Self-grow Kits – Open the packet, add water, and wait for your seeds to sprout. These types of kits are best for beginners or those with black thumbs.
Bulk Seeds – Cat owners with grass growing experience may lean toward purchasing their cat’s favorite grass seed in bulk to save money. You will need your own soil and planters to use bulk seed.
Live Plants – This is the easiest option as you purchase live cat grass from either a brick-and-mortar store or online. The grass is delivered to your door and all you need to do is put it out for your cat to eat.
Cat Grass Growing Pointers
There are many kits and seeds on the market for cat owners that want to grow their own grass.
Here are a few tips to help you on your grass growing journey:
Read the directions thoroughly before trying to grow your seeds, whether you are planting the seeds yourself or have a kit.
Understanding how the seeds germinate will be vital for success. Some seeds need to be wrapped in damp paper towels and put in a dark, humid space to get them to sprout properly. Determine what kind of seeds you have and plan accordingly.
Plant your seeds in a container that is deep enough for the roots of the grass to take hold. Cat grass planted in a shallow container will not last as long as one planted in a deeper container with room for the roots to spread out.
Be careful not to overwater or underwater your cat grass. Overwatering will lead to root rot and mold. Underwatering will lead to stunted growth and yellow grass. Check your kit or seed package instructions to make sure you give the seeds the proper amount of water they need to keep your grass healthy.
If you purchase live plants, make sure you put the containers in at least an inch of water 1-2 times a day for about an hour. The roots of the grass will reach for the water and soak up what they need. This will prevent your grass from turning yellow and your plants will last longer.
Cat grass is a treat. If your cat isn’t used to grass, be careful that it doesn’t eat too much and get sick.
Keep the grass in a sunny area to promote growth and remember to water it according to the package directions.
