Cat Grass – DIY

My first attempts with growing my own kitty grass were not the greatest of hits so it might take a bit to settle into growing your own cat grass, but it is very rewarding once you get into the habit. If you want cat grass available for your cats, it is something you will have to keep growing yourself or buying, since cat grass will only last about two weeks of grazing before it’s all done.

After struggling with different containers to grow cat grass, I saw this heart shaped bowl at the Dollar Tree and just knew it was perfect. The glass is quite heavy so it doesn’t move around, it is shallow and it’s a heart to show Cooper and LeeLoo just how much I love them. There is a flaw in the glass on the top, which is probably why it ended up at a dollar store, but the fur kids won’t notice and I think it adds character.

If you buy in bulk it will be a bit cheeper. I got my Growstones and Petsprouts on Amazon and have used them many times with little impact on the bags.

Step 1: Get Your Supplies Together

You will need:

  • Some sort of growing media: potting soil, grow stones, etc.
  • Wheat, barley or rye grass seeds that are untreated.
  • A shallow, heavy bowl.
  • Coffee Filters

Step Two: Put Everything Together

Fill your bowl about half way with your media and cover with the coffee filter.

Add water up to the coffee filter and then add a layer of seeds on the coffee filter and trim off any filter that comes above your bowl so that it looks like the pictures below.


Tip: don’t flatten out the seeds until the water is in there. Once the grow stones start to float (yes, they do float) it is easier to smear the wet seeds around and get a more even layer without being excessive with the seeds.

Step Three: Bring on the Sun

Find a sunny window your cats can’t get to and let it grow.

Cooper was so excited to test this grass the first time that that he pulled it down off the window sill when the seeds had only just started sprouting and SMASH! No more heart shaped bowl and one very scared, but luckily unharmed, kitty.

Also luckily, I found another heart shaped bowl and started again. At this stage you mostly just let the grass do it’s thing, but peek in on it to make sure the water doesn’t evaporate away and that the roots have hydration.

After only a few days (up to a week) in the sun, it’s ready for grazing:

And Cooper sure loves to graze.

And graze, and graze.

About the third time growing Coopers grass, it only took about three minutes to set everything up so it’s really much easier than driving to the store to buy pre-grown cat grass, but the cat’s don’t seem to care how it comes so do what ever is easiest for you!


Eating cat grass can make your cat vomit. If this is the first time your cat has had cat grass, limit his access to it to only short gnawing phases. Cooper gorged himself so much on cat grass the first time that we had quite the interesting vomit, but if we only left it with him a little and put it back out of reach, he soon learned to pace himself so we can now have it out at all times and he will just chew on it when he feels like it without vomit repercussions.
