    4Petlinks Nibble-Licious Organic Cat Grass Seeds

    Petlinks Nibble-Licious Organic Cat Grass Seeds give you the freedom to control the growing environment you want for your plants. Though you have to purchase the potting soil and container separately, this selection may pay off in other ways.

    Cat grass lasts longer when you plant it on a deeper container, and buying the seeds gives you the ability to choose your own. Plus, you can decide just how much grass you want to grow at one time. You can savor the seeds, so your cat doesn’t go through it so quickly. You can really stretch your buck.

    These certified-organic oat seeds are grown and picked in the United States. Since there isn’t a kit set up, you have to be very careful not to overwater or underwater the plants. If you’re a novice grass grower, it could be challenging to get it right at first.

    Pros
    • Control over planting
    • Certified-organic oat seed
    • Sourced in the USA
    Cons
    • No starting kit

    5. The Cat Ladies Organic Pet Compostable Grass

    5The Cat Ladies Organic Pet Compostable Grass Grow Kit

    If you are looking for a bulk choice, so you don’t have to repurchase so often, consider The Cat Ladies Organic Pet Compostable Grass Grow Kit. It has 3 different 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 something 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 4-6 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.

    Pros
    • 3-pack
    • Organic seed medley
    • Great for multi-cat households
    Cons

    6. Van Ness Oat Garden Kit

    6Van Ness Oat Garden Kit

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

    That back of the package has step-by-step instructions. If you follow them, 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 life of the plant.

    This selection is great, especially 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 offers a “buy 3, get 1 free” deal, so it may be worth it for you.

    Pros
    • Great for novice growers
    • Sprouts quickly
    • Buy 3, get 1 free deal
    Cons
    • Not a super high yield

    7. Bergan Turbo Scratcher Cat Grass

    7Bergan Turbo Scratcher Cat Grass

    Bergan Turbo Scratcher Cat Grass is an attachment to another component. If you want to get creative, you could buy this along 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, 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 have to buy additional products, it may be an exciting toy and treat to make your kitty’s day.

    Pros
    • USA sourced
    • Lush grass
    • Part of a bigger set up for your cat to enjoy
    Cons
    • May not want additional products

    8. Catit Cat Grass

    8Catit Cat Grass

    The Catit Cat Grass Kit will save you some time when it comes to getting the whole thing going. 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 that has 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 it to a well-lit area so it can get appropriate sunlight.

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

    Pros
    • All-in-one
    • Easy instructions
    • Recyclable
    Cons
    • Shorter life expectancy
    • Takes a bit longer to grow than other products

    9. Imperial Cat Easy Grow Cat Oat Grass

    9Imperial Cat Easy Grow Cat Oat Grass Kit

    Imperial Cat Easy Grow Cat Oat Grass Kit is a great choice if you want quick sprouts with minimal work. Everything in the kit is separated into individual packaging, so you will have to set up and assemble. Even though it can take some time, 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 really need.

    This cat grass molds 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.

    Pros
    • Pesticide-free
    • Only oat seed for easy digestion
    • Freshens breath
    Cons
    • Easily molds
    • Not as high of a yield

    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 just to have their cat gnaw them to stems. Plus, it isn’t healthy for them. Many plants are toxic, and even 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. All you need is seeds, soil, and sunlight to get the plant to sprout. It’s usually very low maintenance and easy to handle. Many cat grass options come prepackaged with a starter kit or as standalone seeds.

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

    What Makes Cat Grass Beneficial?

    Cat grass can help your kitties in a few different ways.

    Some benefits are:
    • Roughage in the diet
    • Reduction of hairballs
    • Deters houseplant eating
    • Packed with vitamins and minerals
    • A great form of fiber
    • Cats consider it a treat
    • Chlorophyll replenishes blood cells
    • Freshens bad breath

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

    • Bulk Seed—these are just the seeds, and nothing else. You can also buy replacement seed packs or just the seeds. Experienced cat grass growers may already have a planter or two with soil ready to go. You can also buy cat grass seeds in bulk.

    The most common types of cat grass are:
    • Oat Grass
    • Wheat Grass

    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 certain plants aren’t necessarily poisonous, they can cause unwanted side effects like nausea, vomiting, and diarrhea.

    If your cat suddenly started eating plants or outdoor grass for no apparent reason, you should always take them to a vet checkup just to be sure there’s nothing you’re missing.

    Toxic Houseplants to Remember

    Here are some plants to keep away from your feline:
    • Jade
    • Lilies
    • Azaleas
    • Mistletoe
    • Tomato

    You can read a full list of toxic houseplants provided by Hills’ Pet Diet here. If you have specific plants, you can always research their types to see if they’re dangerous for your indoor 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 a bigger 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 a number of potential 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 can call for different directions, so make sure to 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 grass roots, which kills the plant. Underwatering can make a lackluster patch that browns or dies.
    4. Your cat shouldn’t eat grass sprouts. Make sure that 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 quicker.
    5. Remember to offer the grass as a treat. When your cat isn’t chomping, 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 offer your cat their own cat grass, they may just snub their nose and walk away.

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

    Do Cats Need Plants to Survive?

    The short answer here is no—cats don’t need plants to survive. They are strict carnivores, meaning they naturally only consume animal protein. Because meat and water are the only dietary needs your cat has, they don’t reap a huge 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 simply helps cats who are 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 is an essential common grass without potentially harmful chemicals or additives.

    Catnip and catmint are both in the mint herbal family. Catnip has a mental shift effect on cats, and catmint has none.

    cat paw dividerConclusion

    When it comes to cat grass, the Pet Greens Self Grow Garden Pet Grass is our favorite because of its simplicity, high yield, and longevity. It has everything your cat could ask for in terms of crunchy greens.

    But if you’re looking to get the most value out of your cat grass purchase, don’t forget about SmartyKat Sweet Greens Cat Grass. It’s just as nutritious and effective—and you save a few extra bucks when you buy.

    In any case, hopefully, our reviews helped you pinpoint the right batch for your cat. Best of luck saving your innocent decorative plants from your house panther!
