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:

  • 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

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!

Step 4: The Waiting Game

The second or third day you should see little sprouts coming up from the soil. Check that the soil is still moist every other day or so.

As soon as the grass gets to the size in the second photo, take off the plastic wrap and keep in a nice sunny place. I set mine on the back porch so the kitties would not be temped to eat it yet!

When your grass is 4-6 inches, feel free to let them have a go at it! It normally takes about a week to get to this size.

If you don't wait until the grass is high enough, chances are your cat with destroy is really quickly. :D

Step 5: Bonus Cat Photos

As the resident cat lady I feel it is my duty.

Big Dee likes to put her whole face in the grass. Luna always looks like a crazed murderer when she eats it.

Hi Jessy. Me again. Is it ok to put my now growing kitty grass outside where it's warmer and sunnier then in my apartment? Thank you. Spots mom.

Definitely! Make sure to keep it out of direct sunlight, though. The soil in the pot can get a little too hot and hurt the grass. :)

I just got a new cat grass kit with poor instructions. It said to stir the seeds into the soil. Is that ok? Then no instructions after that. I planted yesterday. Now what? My elderly boy, Spot, loves kitty grass.

It should be okay! Some of the seeds that are lower in the soil may not sprout at first. Just keep it moist and in a warm spot and you should have grass peeking out in no time! :D

Thank you for answering my question. My grass is sprouting, however much of it is coming up and is a very light tan. One got tall and I touched it. Well the very tip broke off so I thought I would pull the rest out and the rest of the tan covering came off to reveal a tiny blade of grass. Many of the other sprouts have the same Light tan covering on them. Help!

Is there a way to do this for a 2 car household? Can it be done such as we can grow it continuously without having to replant all of the time? How much area would it take? Winter in Michigan can be harsh so we will need to be able to do this indoors during that time. Thank you.

The only way I've accomplished keeping it going all the time is to do two pots of cat grass. Let them destroy one while the other grows! I do find I need to add new grass seed to the containers, though - my cats love to rip it out by the roots. :P

Thankfully you can mostly keep it contained to a windowsill for growing, though!

Hi Jessy,

Thank you for sharing this!
I have followed your instructions and got the grass to start growing (like in your picture #2) and then I put it outside on our porch. It has been 2 weeks since I took it out and the grass has stopped growing. Did I take it out too soon? It has been pretty cold and even snowy a bit, could that be the reason?
Would appreciate your input.
Thanks!

Talia

The cold probably shocked it! I honestly try to keep my grass inside since it easily wilts with heat and cold. :)

my cat grass used to look like yours, but lately can only find "cat grass" pkgs that are oat seeds (see pic...seeds are different from yours) and yes, i've had to go back to buying the already grown grass in the pet stores, but since they are fully grown they don't last much longer after purchase. I will continue my search for wheat grass seeds next shopping trip, but as I mentioned can only find the seeds in my pic. I will try the nurseries again too.

I want to start growing kitty grass and want to know if you used a non-draining pot. I have one I want to use but there are no drainage holes. Thank you!

it is best to use a pot from which the water can drain. No drainage can reslt in the roots just kind of rotting. and mold can build up in the pots -- not likely to be good for kitties.
