Some Cats May Eat Grass Because They Enjoy The Taste

It sounds almost too simple but some cat eat grass because they genuinely enjoy the taste and texture of grass. Eating grass isn’t necessarily a sign that your cat has a nutritional deficiency or is trying to move a stubborn hairball it may simply mean that your cat likes the flavour of grass.

Reasons Why Your Cat May Vomit After Eating Grass

Grass may cause your cat to throw up too however this is not always a bad thing, cats sometimes use grass to stimulate the pharyngeal reflex (responsible for gagging) which will cause them to vomit thus helping in dislodging foreign bodes from their stomach including things like; hairballs, bone fragments, potentially harmful germs and any other piece of rubbish they they may have inadvertently swallowed.

One thing that it is important to be aware of is that if your lawn has been treated with pesticides then this can potentially be harmful to your cat, so if your cat does enjoy eating your lawn then avoid using any pesticides.

A better, safer and more nutritious alternative to lawn grass is specially grown cat grass.

What Is Cat Grass?

Cat grass is grass which is grown specifically for cats to eat.

The Latin name for the most common form of cat grass is Avena Sativa which is the common oat, the type you can make porridge from. However although this is the preferred grass type for cats it is not the only type of grass which is suitable.

Flax, Barley and Wheat grass are also often referred to as cat grass, catnip is often categorised as cat grass too however catnip is not a grass.

How To Grow Your Own Cat Grass

It is well worth ensuring that you have cat grass available for your cats to eat, failure to provide cat grass will mean that your house plants will definitely suffer or your cats will resort to eating plants outside which may have been treated with pesticides which could make them very ill.

Cat Grass is very easy to grow

Fortunately cat grass is very easy to grow, all you need to grow cat grass is:

  • a small bowl
  • some compost or soil
  • Cat grass seeds
  • a plastic wrap
  • some water

Once you have gathered everything you need then follow these five simple steps:

  1. Fill the bowl half full with soil and add the seeds on top.
  2. Cover the seeds with another layer of soil about 5mm deep.
  3. Water the seeds so that the soil feels nicely moist but not sodden.
  4. Cover the bowl with the plastic wrap and leave it in a warm dry place.
  5. Remove the plastic wrap in a couple of days with the grass grows through, it should take about no more than one week of growth until the grass is ready for your cats to enjoy.

How Long Does It Take To Grow?

You should start to see grass shoots a couple of days after planting and watering your seeds, these should then grow quite quickly and within 7 – 14 days (depending on the seed and how favorable the growing conditions are) they should reach their full optimal height of around four inches. At this stage it is ready for your cat to eat it.

How Long Does It Last?

Cat grass has quite a short life-cycle and will usually die within 10 – 21 days. With a bit of luck your cat grass may survive a full month however when it does discolor and start to wilt you should throw it out and plant some new seeds.

To extend the life of your cat grass for as long as possible keep your grass in a place where it is exposed to as much natural sunlight as possible and water it regularly. It is important to make sure you don’t over-water your cat grass though, using a spray bottle is a good way of replicating the dew that would feed them in the wild and will prevent over watering.
