How to Grow Cat Grass Without Dirt

One of the easiest ways you can keep your cat healthy, is to offer them Cat Grass along with their food. I’m excited to share with you How to Grow Cat Grass without Dirt and why it’s important.

How to Grow Cat Grass {without dirt}We have 2 cats, or should I say there are 2 cats that live in this house and we’re grateful that they allow us to live with them?! In complete seriousness, I love my cats (Lainey 14 and Baloney 10) even though I’m not really a cat person, I totally prefer dogs, but after all these years these 2 felines have definitely found a place in my heart.

Cats really do their own thing and as long as their human slaves keep up with food/water/litterbox cleaning they are relatively peaceful to live with. At least our very aloof girls are. Neither of our cats wants to snuggle or cuddle. Weeks can go by before I realize I haven’t even forced myself upon them by unwelcomely hugging-squeezing-loving them.

While our girls are welcome to go outside whenever they want (most often at 3:30 am) they still really enjoy having a little cat grass available to nibble on indoors.

What is Cat Grass?

Not to be confused with catnip, which is a member of the mint family, cat grass is typically grown from rye, barley, oat or wheat seeds. Nibbling on grass is a natural behavior for all cats. If you have an outdoor cat, chances are it’s part of your kitty’s daily routine.

If your pet spends all or most of its time indoors (like most domestic cats), you may want to consider growing cat grass in your home.

Cat Grass also gives your cat a healthy alternative to nibbling on houseplants and flowers, many of which are toxic to cats!

Why do Cats Eat Grass?

“Research has not yet shown why cats eat grass, but we have several ideas,” said Carlo Siracusa, animal behaviorist of University of Pennsylvania School of Veterinary Medicine. “In the wild, cats eat grass after they have eaten their prey. In many cases, the grass causes the cat to vomit. We believe this is nature’s way of helping the cat expel the parts of their prey that are indigestible.”

Even if your indoor cat has never caught a mouse or bird, she will instinctively be attracted to cat grass. Why? “It’s a behavioral instinct,” Siracusa says. “Grass is also a form of fiber that helps cats either throw up hairballs or digest them by acting as a laxative.”

Another theory is that cats may eat grass for some trace minerals and the vitamins A and D. Grass also contains chlorophyll, which, before the discovery of antibiotics, was a remedy for pain, infection, ulcers, skin diseases and anemia. Grass also contains folic acid, which helps with the production of hemoglobin, the protein that moves oxygen into the blood to help kitty’s circulation. Plus, there’s the benefit of breath cleansing chlorophyll.

  1. HI – just ordered my supplies to make. Question – do you just leave it out so they can eat as they want or can they get too much?

    1. You can leave it out 24/7 – they will self regulate. Think of cats outside with access to fresh grass, they know when to enjoy it and when they’ve had enough.

  2. Is there anything that you can find around the house that you can use as an alternative to grow rocks ? I’m trying to grow some cat grass for my cat but don’t have the money to spare for the rocks .

  3. I grew my cat grass as per your instructions. It’s amazing how fast it grows. You can almost see it grow right in front of your eyes!
    Well, my cats are not cat grass eaters. I’m hoping they might start eating it🙏🏼 Thanks for the great instructions.

  4. The linked grow stones are not available. Is there another alternative? What type of stones should I look for do you think?

  5. Was wondering if this technique will stop gnats? I have a problem with that currently growing the cat grass.

  6. Hello, I just moved to an apartment and am trying to keep my now indoor kitty happy. Can the grown stones be re-used to your knowledge?

    Thank you so much !

  7. I’ve refreshed and reloaded your article several times but none of your photos is appearing. 🙁
    I would love to see the, all as part of the “tutorial”.

    1. I’m so sorry that your having a difficult time viewing the photos in this post. Unfortunately it is not an issue with my site, I have confirmed that the photos are visible for others. I suggest reaching out to your internet provider or trying a different internet browser.

  8. The Growstones I bought says gnat control. Is that safe for cats? I’m hoping it’s a safe, natural control, as it says to cover surface of soil with the stones. Thank you

  9. Do you have any updated suggestions for the links above? The seeds and grow stones seem to be unavailable at this time. Thank you!

  10. Hi! Do you know of a way the revive one of this plants? It grew very well at the beginning but from one day to another it dried itself and cant seem to grow again.

  11. I think this is great. I’m glad I found it. But my coffee filter gets moldy. I am using unbleached filters and filtered tap water. Should the water be changed while growing? Should I use bottled water?

    1. How long has your cat grass been growing? Are you using growstones? How quickly is the mold growing?

      1. After the seeds start to sprout so a few days white fuzz covers the non bleached filter or paper towel. I am using growstones. Any ideas?

    1. You can try. Since they are porous and typically have a hole in the bottom, those pots don’t normally hold water well so you’ll have to add water and it may make a mess.

  12. At any time are holes poked into the filter for the roots to reach the stones because some seeds sprouted and are loose and falling over and stay on top of filter overall I don’t have a thick growth as your photo (I used 3 smaller clay pots instead). Thanks much, love this idea!

    1. by filter do you mean the paper towel? the roots will form a mat. they only need moisture which they get through the paper towel.

  13. Very useful article, thank you very much, very creative approach to such a thing as growing grass for a cat. Grass garden is very very beautiful and stylishly vygldit, and also how much benefit this can bring to your beloved cat!) “Cats really do their own thing and as long as their human slaves keep up with food / water / litterbox to live with. At least our very aloof girls are. “Neither of our cats wants to snuggle or cuddle.” But this is a very correct idea and many owners of cats do not understand it yet.

    1. Not necessarily cover, the paper towel wicks the water up to the seeds to keep them damp.

    1. you can use any stones, but be careful. heavy stone make breaking the jar easier and it’s overall heavier. You will also probably have more alge

  14. I had a go at this but as soon as my cat started pulling on the grass, she managed to pull the coffee filter paper out! How do you avoid this please?

  15. I’ve had the cat grass growing for a couple of weeks & noticed today it smells terrible. What did I do wrong?

  16. I just put my first seeds out to grow. Do they need sunlight to grow? Where should I put this to grow it?

  17. Does it have to be a clear glass jar? Or can a regular planter work. Wondering if the roots need to see light, hence the glass jar. I too have stopped growing grass because the soil needs to be completely dumped and refilled each time (which the grass only lives about 2 weeks). Thanks.

  18. I quit growing grass for my 3 cats because they would pull the grass, roots and dirt out of the pot. What a mess! They wont eat the grass that I cut for them, so I gave up. I can’t wait to try your method. Thank you.

  19. Sprouts are also very good for our dogs, so the cats need to move over and share. I like this article by Karen Becker
    http://healthypets.mercola.com/sites/healthypets/archive/2015/09/06/pet-sprouts.aspx

  20. I have grown oats and wheat in dirt for my cats many times but I end up with dirt full of roots that I have to dump out and fill with new dirt to start over. This seems so much easier. I’m going to try this. Thanks for the idea. :-))

    1. There are links to everything you need, including the seeds in the post. You’re just one click away 🙂

  21. I’ve grow cat grass for my cat’s because they are indoor cat’s only. I get it at Wal Mart but they don’t seem to like it much. is it the same grass? they have plenty of fresh air with the windows open. MUCH healthyer by being indoor cats only. I’m going to try this maybe they will kike it better. Thank you for this idea.

    1. Toni – I’m not sure of the variety of grass you are buying but I do know that our cats love homegrown.

  22. I grew it for Cowboy’s Birthday in April. Just started another batch yesterday but will definitely try this method next time!

  23. My 2yr old rescue cat appreciates everything I do for her and shows me love & affection every day. She is an indoor girl and I’m going to get this started today. I know she will love it! Thanks so much??

  24. I need to try this! It’s so funny because I totally didn’t peg you as a cat person 😉 They get into your heart though!

        1. They are lightweight stone specifically used for growing plants, just CLICK on the word Grow Stones in post to learn more about them and where to purchase.

          1. the grow stones a re not available at amazon. any other ideas to substitute them?

        2. Please, what are growing stones, I understand the concept. Can I buy the in Queensland , Australia.
          I have adopted an 8 year old cat from a friend who had to get ‘rid of him’ (how disgusting). He has settled in really well with myself, my two dear little dogs, he walks the yard with me while I attend to my 5 Avaries. He doesn’t like to be nursed or cuddled, but he does love his tummy and chin scratched and his head stroked. So I am learning all about cats as I have always been a dog person. He is also being very good and learning to stay indoors at night. Now anyway.
          As I am new at living with a cat, I want to do the best for him. Thanks for any information on my request. BC.

          1. Thank you for saving the kitty! Just click the link for the grow stones in the post and you’ll get all the info you need.

      1. Try 18 cat’s feeding, water and litter boxes.
        The litter and food cost is over the roof but we do this for the love of animals.
