How to Grow Wheat Grass for Cats

Try growing some grass inside.

Try growing some grass inside.

Unless you are extraordinarily unobservant, you’ve noticed that cats are nothing like cows, especially in terms of diet. A cat’s habit of eating a bit of grass is nothing to do with nutrition -- he cannot digest the stuff. Fluffy’s eating wheat grass to help hawk up hairballs.

Fill one seed tray with potting mix or sterilized garden soil if you want to cut costs. Dampen the mix with water.

Sow a handful of seed into the mix. You can make little furrows with your finger or a piece of cutlery if you like and cover the seeds with mix, but it isn’t really necessary -- wheat grass requires little encouragement to germinate. Transfer the remaining seed into an appropriate storage container to keep it fresh and deter pests. Your cat might appreciate a mouse infestation but chances are that you will not.

Place the tray out of your cat’s reach for now, watering it as required to keep the soil slightly damp. Start another tray in the same way a week or so later and repeat, so as you have a continuous supply of grass.

Place the first tray once the grass is a few inches high on a newspaper on the kitchen floor, a windowsill or some other spot your cat can reach.

Items you will need

  • Wheat seeds
  • Seed trays
  • Potting mix
  • Storage container
  • Watering can
  • Newspaper


  • You can work with the smallest available quantity of wheat grass seeds, obtained from an agricultural supply store or pet store, as they go far and are much cheaper than a ready-made wheat grass kit for kitties.
  • Sterilizing garden soil is necessary, because otherwise you might end up cultivating an interesting selection of weeds, some of which may be toxic to cats. Place the soil in an ovenproof dish and bake at about 180 to 200 F for 20 minutes. Allow to cool before use.
