Cat grass is a feline favourite, but unlike catnip, it doesn’t induce a high. Most cats enjoy having fresh grass in the home. The grass family is the fifth-largest plant family on earth with over 700 genera and 9700 species. Cat grass isn’t one type of grass but is made up of several species which are suitable for cats.
Why do cats eat grass?
Grass contains micro-nutrients that are not a part of the meat diet. It is also thought that wild cats eat grass to vomit, which can get rid of intestinal parasites and ingested hair in the process.

How to grow cat grass
Grass is easy to grow; it likes a sunny position and damp soil. If the soil does dry out, the grass will wilt, but will quickly once it has been watered, unless left for too long.
Most garden centres and pet shops sell cat grass in containers, or you can grow it from seed.
How to grow cat grass from seed:
- Fill a pot 3/4 full with premium potting mix
- Add seeds (be generous) and add 1 cm of potting mix over the seeds
- Water
- Keep at room temperature, and out of direct sunlight, seeds should germinate within a few days
- Give to the cat when the grass is 5 to 7.5 cm tall
Tips:
Plant several pots of cat grass and rotate.
A low, heavy pot is safest to prevent the cat from knocking it over when eating the grass.
