It may not be the fanciest-looking cat grass, but the simplicity is worth it. You open the bag, add a little water, and—voila! Your cat grass will start to grow a few days later.

4. Petlinks Nibble-Licious Organic Cat Grass Seeds

Petlinks Nibble-Licious Organic Cat Grass Seeds allow you to control the growing environment you want for your plants. Though you must purchase the potting soil and container separately, the PetLinks seeds may pay off in other ways.

Cat grass lasts longer when you plant it in a deeper container, and buying the seeds allows you to choose your own. Plus, you can decide how much grass you want to grow at one time.

The certified organic oat seeds are grown and picked in the United States. Since it isn’t a kit, you must be careful not to over-water or under-water the plants. It can be challenging to get it right if you’re a novice gardener.

5. The Cat Ladies Organic Pet Compostable Grass

If you are looking for a bulk choice so you don’t have to repurchase often, consider The Cat Ladies Organic Pet Compostable Grass Grow Kit. It has 3  grass growing packets, so you won’t have to worry about replenishing your cat’s supply for a while.

This product is an excellent selection if you want a grass that’s completely natural and free of any chemical compounds. It has 100% organic wheat, oats, barley, and rye. The container is BPA and GMO-free to keep your kitties safe and healthy.

If you follow the instructions, the grass should sprout within 4 to 6 days. Your cat can enjoy the sprouts of luscious grass for a few weeks, and when it dies, you have a backup ready to go. It keeps things easy, especially for multi-cat households.

6. Van Ness Oat Garden Kit

If you want a small setup that gets the job done, take a look at the Van Ness Oat Garden Kit. The only grass in this kit is oats, and the soil is peat moss. It’s organic and delicious for your kitty.

The back of the package has step-by-step instructions, and you should see sprouts within 3–7 days. The container isn’t very deep, so the grass’s roots won’t take a good hold, which could limit the plant’s life.

This selection is great if you haven’t grown grass before. But, in our experience, the grass didn’t sprout as thick or healthy as shown in the image. However, the company has a “buy 3, get 1 free” deal, and it may be worth it for you.

7. Bergan Turbo Scratcher Cat Grass

Bergan Turbo Scratcher Cat Grass is an attachment to another component. If you want to get creative, you could buy it with the Bergan Turbo Scratcher or Star Chaser for a unique approach to cat grass enjoyment.

The other pieces include a scratch ring and a tinkle ball chaser, which creates a circular design. So, not only does your kitty have a lush patch of grass in the center, but they can chase the ball, too.

USA-sourced vermiculite and wheat seeds take about 3 days to sprout after the initial setup. The lifespan of each grass replacement filler is approximately 3 weeks. Even though you must buy additional products, it may be an exciting toy and treat to make your kitty’s day.

8. Catit Cat Grass

The Catit Cat Grass Kit will save you time when growing cat grass. It’s an all-in-one deal to conquer hairballs and house plant eating once and for all. The product comes in a prepackaged plastic tray with the soil and seed intact.

You just open it up, add the recommended amount of water, and place it in a humid area. After you see sprouts, you can move them to a well-lit area so they can get appropriate sunlight.

The packaging and container are recyclable, which is an extra perk. The grass sprouts in between 5 and 10 days but won’t be ready to eat until it reaches 4 inches tall. The container is shallow, so the life expectancy of the grass may not be as long.

9. Imperial Cat Easy Grow Cat Oat Grass

Imperial Cat Easy Grow Cat Oat Grass Kit is an excellent choice if you want quick sprouts with minimal work. Everything in the kit is separated into individual packaging, and though it can take some time to organize, after that—it’s a piece of cake.

It contains a prefilled peat moss bedding that you add the seeds to. The oat seeds are pesticide-free and sourced from the USA. An upside to oats is that the chlorophyll freshens your cat’s breath, which some cats need.

This cat grass grows mold easily if you don’t properly maintain it. So, make sure that you aren’t overwatering and that you keep it in a well-ventilated area. Sometimes, it grows unimpressively or not at all.

Buyer’s Guide: Selecting the Best Cat Grass

Let’s face it—no one likes to work so hard getting their houseplants lush and healthy to have their cat gnaw them to the stems. Plus, it isn’t healthy for them. Many plants are toxic and sometimes deadly for our feline friends.

Cat grass was thought up by a few cat lovers to combat this problem while adding a little fiber to their daily diet. Is cat grass a cure-all solution? You decide.

What is Cat Grass?

Cat grass is a combination of different grass seeds that grow indoors in a container. You only need seeds, soil, and sunlight to get the plant to sprout. It’s usually very low maintenance and easy to handle. Many cat grass varieties come prepackaged with a starter kit or as standalone seeds.

While it may sound like normal outdoor grass, that isn’t the case. Outdoor grass can contain harmful chemicals, bacteria, and other substances your cat is better off without. Cat grass is safe for your feline.

What Makes Cat Grass Beneficial?

Cat grass can help your kitties in a few ways.

If you’re offering cat grass for dietary perks alone, it may not be much of a help regarding nutrition. However, it’s much better to have your cat munching on healthy greens rather than toxic ones.

Types of Kits

You can pick from plenty of choices when you decide to try out cat grass.

Types of Cat Grass

You can buy individual grasses or a medley combination.

Many cat grass products have medlies of all seed types, while others have one. Be sure to read the label to see what each brand offers.

Cats + Houseplants = Bad News

If your cat has destroyed one of your favorite plants, you know how it feels. But apart from your feisty feline killing off your greens, it can have serious health consequences for them, too.

Even if the plants aren’t poisonous, they can cause unwanted side effects like nausea, vomiting, and diarrhea. If your cat suddenly starts eating plants or outdoor grass for no apparent reason, you should always take them to a vet checkup to ensure there’s nothing you’re missing.

Toxic Houseplants to Remember

You can see a list of toxic houseplants provided by Hills’ Pet Diet here. If you have plants, you can always research their types to see if they’re dangerous for your pets.

Pay Attention to Your Cat’s Behavior

Trying to chew on plants may be normal behavior for most felines. However, it can sometimes point to an underlying health issue, such as a lack of nutrients in their diet.

If your cat starts eating plants out of nowhere, or if you see them eating soil, it can happen due to a deficiency of some sort. It might also be because of gastrointestinal upset, which can stem from several issues you won’t want to overlook.

Cat Grass Growing Tips

Here are a few tips to get the most out of your cat grass purchase:

1. Each cat grass kit has different care requirements, so follow the instructions on the package.
2. Try to plant seeds in a deep container. If the grass’s roots can anchor down further, it can help the longevity of your cat grass.
3. Be sure not to over or underwater the cat grass. Overwatering can lead to moldy soil and rotten roots, which kills the plant. Underwatering can make a lackluster patch that browns or dies.
4. Your cat shouldn’t eat grass sprouts. Ensure your grass is 3–4 inches high before encouraging them to chow down. Prematurely eating the grass has no nutritional benefit to your cat, and it causes the plant to die quickly.
5. Remember to serve the grass as a treat. Keep the grass in a sun-soaked area to promote healthy growth.
6. When it comes to watering your plant, different kits will call for specific measurements. But a good rule of thumb is to water your plant when the soil is dry to the touch.

Will All Cats Enjoy Cat Grass? 

If your cat is a plant-chewer, there’s an excellent chance they will adore having cat grass around. But that doesn’t mean all cats will show an interest. We all know how picky cats can be about what they put in their mouth. If you serve cat grass, they may snub their nose and walk away.

Cat grass is usually best for cats interested in eating plants. If they haven’t eaten them before, your cat grass purchase may be a bit of a gamble—left to the discretion of your kitty.

Do Cats Need Plants to Survive?

Cats don’t need plants to survive. They are strict carnivores, and they only consume animal protein. Because meat and water are your cat’s only dietary needs, they don’t reap a nutritional benefit from eating cat grass.

Most cats will regurgitate the grass rather than digest it. Their bodies don’t have the enzymes necessary to break down plant-based material. Cat grass helps cats prone to hairball issues by putting fiber in their diet.

In short, the rewards are less nutritional but are better alternatives to eating other harmful plants.

Are Cat Grass, Catnip, and Catmint the Same?

Cat grass is different from catnip and catmint. Cat grass does not produce a stimulating effect when cats consume it. Catnip and catmint are both in the mint herbal family. Catnip has a mental shift effect on cats, and catmint has none.
