Picture of how to grow cat grass
Cat grass is something my cats LOVE. It's a special treat for them - we try to keep it around most of the time. It keeps them entertained and happy. :D

Plus, it's super cheap and easy to grow! It'll take about a week to get it to a good height, but after that, it's a grass eating free-for-all.

More cat pictures on the last step - Big Dee and Luna spent forever grazing when I set it out, and I took waaaaaay too many photos :D

Step 1: What you need:

Picture of what you need:
  • a small pot to grow in
  • organic potting soil
  • cat grass seeds
  • plastic wrap
  • water
I say organic potting soil because your kitties are going to be eating this and probably digging around in it when you're not looking. Avoid potting soils with lots of fertilizer in them - the cat grass doesn't need it anyway since it won't last long. :)

Cat grass can be many different types of seed, but it's typically oats or wheat. You should be able to find it in your local pet store pretty easily! And the good news is the seed lasts forever. The seed I'm using for this is some that was given to me 5-6 years ago by a friend for babysitting her cat. :D

Step 2: Planting

Picture of planting
Fill your pot with soil, stopping 1-2 inches from the top. Scatter a handful of cat grass seed over the top of this - I like to do one thin, even layer.

Then add a couple of handfuls of soil over the top so the seeds are covered with about 1/4 inch of soil.

Step 3: Water and cover

Water the seeds with 1/2 cup of water or so - you want the soil to be nice and moist.

Once that's done, cover the pot with plastic wrap (not too tightly - you still want a little airflow!) and set in a warm and dark location - I keep mine on top of the fridge!

I love this idea. One of my cats has hairball issues, the other doesn't. I have two thoughts though:

1. What about using a plastic liner to help stave off rusting of the pot. Even coated pots will eventually rust and the damage will be hidden on the inside until too late.

2. If you place a layer of gravel in the bottom, it helps reduce the chances of over-watering since it gives a place for the extra water to go.

The outside bird cage also inspires me to come up with a way to keep my babies out of the pot itself.

Lovely Idea,

Suzanne in Orting, WA

Or you could use a plastic pot /container to grow it in

Hello! How long does the grass last? Seems to turn brown quickly....not enough light maybe? I got a new batch going but hate to waste the old batch. Do seeds resprout? The grass that turned brown I snipped low and now don't know what to do with it. Lolol

Normally around two weeks for us! Between the cats constantly chewing on it and the lack of nutrients in the soil it never lasts very long. :)

Composting the old batch is a great way to get rid of it!

How often are the seeds supposed to be water and what amount?

jessyratfink (author)  PattyH31 month ago

Before they sprout, just make sure to keep it nice and moist, but not drenched. I normally just check it every morning to see if the soil is light or dark.

Once it's sprouted and growing, I'd say a light watering every couple days is good - maybe 1/4-1/2 cup depending on the size of the container you use and how much drainage you have.

Do you use seed starting soil?

jessyratfink (author)  ReneeN1 month ago

Nope! Just an all purpose potting mix. We normally use Happy Frog soil for everything.

OH NO, I'm a total failure at Cat Grass!! Used a plastic container about 4" high X 5" diameter, punched holes in the bottom, filled with organic seed starter soil, left 1/2" room on top (maybe too much?), then soaked the soil. Sprinkled way more seeds than you show you did on the top. Put 1/4" of soil over seeds, gently watered again. Covered, put in a non lit place. It took more than a week to see any grass at all. What finally emerged (top off of course) was VERY sparse. Yours looks so lush and you used far less seed than I did. OOOOOHHHHH, what am I doing wrong?

jessyratfink (author)  deebeebrez1 month ago

It could be that your seed was bad! Super old seeds or those that have gotten too hot or cold tend to lose their ability to sprout. I would try it again with a little less water and fresh seed. :)

I need help!!!!!!!!!!! I am very worried!!!! I bought some cat grass today from a farmers market and my cat likes it. But, my problem is that he likes to pull out the grass which pulls out the seed and the roots of that sliver of grass, and eats EVERYTHING! Is that okay or should I cut the grass for him so he doesn't eat the seed/roots/a little tiny bit of soil (organic)? Thank you in advance for your help!

It won't hurt him. If it really bothers you, though, wait until the grass grows a few days more to let the roots establish themselves a little more.

My cats LOVE this stuff. I've got 2 questions for you though. How do you keep it from getting moldy? I think I might be adding too much water but I feel like it dies so quickly if I under-water it. Also, how do you keep it alive? After my cats chew it down pretty far, it starts to die and turn brown.

Thank you for this!! I also had to comment because my Orbit looks a lot like your white kitty with the orange on her forehead and I've never seen another short haired cat that looks like ours :) He's going to love this grass!

Twiiiiiinss!! He's so cute. Love that sassy look :D

Thank you!!!! He was a bit annoyed that I came in to disturb his nap to take a picture, but he's usually super easygoing and friendly :) We found him as a stray at five weeks old so it's super fun to see another kitty out there who looks like him!

Off to go grow some grass for him! Thanks again for a great instructable!

hello, so cats can eat this grass right.
Wow I think you have the most awesome posts on here! Cats rock!
My cat likes to eat this stuff but hes gotten sick from it before. So can they get sick from this too

Cute... but do your cats ever, um, just throw it up afterwards? That's what my boy did and I'm wondering if that's good.
jessyratfink (author)  kcarter21 year ago
Ha! Sometimes. Big Dee especially - sometimes they just get excited and eat too much.

Definitely one of the drawbacks of cat grass! I can't say it's good but it's not bad either. :)

If you're in the UK, go to your local Wilkinsons for a bag of 'Wildly Tasty" bird seed on offer at £1.  There's more wheat seed in there than you'll ever need.  Ozzy isn't anywhere near as wildly enthusiastic about the cat grass as Jessy's seem to be.   
IMG_1732.JPGIMG_1554.JPG
Theyre too cute! :)
FYI: Cat grass is (always? usually?) just wheatgrass, and wheatgrass seeds are wayyyyy cheaper in my hood. You can also take the grass away from them when it's little half inch nubs and let it grow back. It isn't as good the second and third time around, but our birds also go nuts for it.

We keep cat mint, catnip and cat grass in a mini hothouse. It's just 5'x2' with two closure zips.
If we set all three of them out, both cats ignore the grass and mint -- straight for the 'nip.

As they ruminate in the catnip afterglow, we get 5 minutes of peace where they don't fight!

We have 2 black cats

Duff LOVES his cat grass. He's so happy when he gets a new batch!

Dexter, on the other hand, is completely indifferent to it!
My neighbor planted catnip in her front yard and the cats wouldn't leave it alone. So she covered it with a bird cage. It's kinda funny, sometimes you will see one of the cats sitting there staring at he cage, almost like they are just waiting for the plant to grow. They keep it pretty well trimmed.
The cage is a great idea! As long as the main part of the plant can't get abused and die, the cats will be able to reach the extended parts. Plus the cage is an attractive addition to any garden.

- Just remember that stray cats will be attracted also. Vinegar helps with the excess spraying.
It does make a neat addition to her front yard. And there is plenty of space for the plant to grow. And enough surface area to keep the cats happy. There hasn't been much of a problem with strays. The cats that live here are pretty vigilant. hehe

Very pretty!
So sorry to hear that your neighbor did not simply plant MORE catnip....! It is one thing that totally satisfies MOST cats. My Tigger LOVES it and after eating and rolling on it takes a long nap.......it's like his pot! And yet, my Daizey picks at it and then walks away!

Add a small pot or plot to your yard and watch the fun begin!

I have no clue why which is why I am asking. Why do cats like it, and what benefits is there in this??
Not only does it pormote healthier digestion and hairball assistance, it also has nutrients that cats and dogs sometimes are not getting enough of from their food. (No reflection on their humans, though. Sometimes their systems just get off like ours do.)
jessyratfink (author)  wheeljam1 year ago
I know that it helps with digestion, and can help with hairballs too. :) But mostly I just give it to them because they're nuts for it.

I know that dogs like grass too, but they tend to eat it when they've got upset stomachs - it just makes them throw up. Thankfully my cats aren't the same way, but it does happen sometimes. :P
Never knew this either - good to know - my cats have issues with both!
Thanks for sharing. I bought some cat grass a few years ago. It came with gel granules to keep the seeds moist rather than using dirt. I always wondered if the leftover seeds would be ok in dirt. Thanks so much for answering that question! My cats will like your idea SO much better because the grass won't pull out of the dirt as easily and the dirt won't sour and mold the way the granules did. Thanks again!!! :)
P. S. One can NEVER post too many cat photos! Cute dog photos either! ;D

Once I bought some seeds from ebay but where black and tiny not like yours. I plant then in 2 places nothing happened. Ok i said maybe its my fault. Where you get yours?

My cats will love this - your photo - your cat - is sooo beautiful! Hard to the see the one in the back - I'm sure they're both so cute! My cat is the opposite - all black with some white in spots. And her sister - a big colorful fluffball. My cats will appreciate this! :) Thank you!

Also - I am glad I read this because I already bought the seeds - but may not have read the directions thoroughly - wouldn't have known to cover and keep so cool. Thanks!
