What is cat grass?

Cat grass (catgrass) is a name used to describe a number of different types of grass which are popular with cats. There are several types of grass suitable for cats which include:

  • Dactylitis Glomerata (Orchard Grass or Cock’s Foot)
  • Avena sativa (common oat, cat oat)
  • Barley
  • Wheatgrass

Cats lack the necessary digestive enzymes to fully digest grass, which makes them regurgitate the grass back up. In the process of regurgitation, they also bring up indigestible products such as hairballs or feathers.

Other possibilities include:

  • Grass contains some nutrients which aren’t a part of their normal carnivorous diet. Folic acid is an essential water-soluble vitamin which is responsible for a number of functions including metabolising fat, production of oxygen and growth and development.
  • It acts as a laxative and can help with the passage of indigestible objects such as hairballs further along the digestive tract.
  • They like the taste of it.

Cat grass doesn’t harm your cat if he eats it.

Where can I buy cat grass?

Most garden centres, hardware stores, and pet stores sell containers of cat grass. It is also easy to grow from seed.

Cat grass can easily be grown in pots, making it an ideal snack for indoor cats.

How to grow cat grass

Cat grass is an easy plant to grow from seed which should be available from your local garden centre.

  • Add potting mix to the pot.
  • Add seeds evenly over the top of the soil, press down lightly.
  • Water the seeds in.
  • Place on a sunny windowsill. Check daily and water if the soil dries out. The seeds should start sprouting within 5-7 days.
  • Once the grass is an inch or two long, move to a spot easily accessible to your cat. It is also a good idea to have some growing outdoors in an enclosure if your cat has access to one.
