Cat on grass

Cats love grass. But not all grass is good for them.

Some can be toxic or harmful. That’s why you need cat grass.

Cat grass is a special grass mixture you can grow indoors for your feline friend.

In this article, you’ll learn what cat grass is, how to grow it, and how to care for it. You’ll also discover some possible problems with cat grass and how to avoid them.

What Is Cat Grass?

Cat grass is a term that refers to a mixture of grasses that are grown from seeds, such as wheat, barley, oats, or rye.

These grasses are safe and nutritious for cats, unlike some house plants or flowers that can be toxic.

Cat grass also differs from the grass outdoors, which can contain toxic pesticides or other harmful substances.

It is grown indoors specifically for household pets.

The grass allows your cat to engage in natural behavior and enjoy some greenery in her diet.

Why Do Cats Eat Grass?

No one knows why cats eat grass, but there are several theories. Some experts believe cats eat grass to help them vomit, pass hairballs, or add fiber and vitamins to their diet. Others think cats eat grass to satisfy their natural hunting instincts or cleanse their palate after eating meat.

How To Grow Cat Grass?

You have a few options if you want to provide your cat with some fresh and tasty cat grass.

You can:

  • Buy cat grass already grown in trays from your local pet store, online, or even at your veterinarian’s office.
  • Buy cat grass kits with everything you need to grow your own cat grass, including a container, soil, and seeds.
  • Create your own cat grass garden by purchasing your own seeds and pots.

How To Grow Cat Grass From Seeds?

Growing cat grass from seeds is easy.

You can use any type of safe seeds for cats, such as wheat, barley, oats, or rye.

Here are the basic steps to follow.

Sow Your Seeds

Sow cat grass seeds directly into your soil (for growing indoors or outdoors), about a quarter-inch deep.

You can use any small pot or container that has drainage holes.

Fill it with organic potting soil that does not contain a lot of fertilizer.

Dampen the Seeds

Dampen the seeds with water and cover the pot with plastic wrap.

This will create a greenhouse effect and help the seeds sprout faster.

Place the pot in a warm and dark place, such as a closet or a cabinet.

Water Daily

Check on your seeds every day and lightly water them to keep the soil moist but not wet.

You can use a spray bottle to avoid overwatering.

You should see some sprouts in a few days to a week.

Place in Indirect Sunlight

Once the seeds have sprouted, remove the plastic wrap and place the pot in a warm spot in your house that gets indirect sun.

Avoid direct sunlight, which can burn the grass.

Rotate the pot every day to ensure even growth.

Let It Grow

Don’t let your cat eat the cat grass until it grows tall enough (about 4 to 6 inches or 10 to 15 cm high).

It will take about one to two weeks for the cat grass to be ready for your cat to nibble.

Factors To Consider When Growing Cat Grass

To ensure your cat grass grows well and stays healthy, choose the best location, container, soil, and seeds for your cat grass garden.

Here are some tips to consider.


Choose a warm, bright, and safe location for your cat.

Avoid places that are too hot, cold, or drafty.

Also, avoid places near toxic plants or chemicals or where your cat could knock over the pot or spill the soil.


Choose a container that is small enough to fit in your chosen location but large enough to accommodate the growth of the cat grass.

Make sure the container has drainage holes to prevent waterlogging.

You can also use decorative pots or baskets to make your cat grass garden more attractive.


Choose an organic potting soil that does not contain a lot of fertilizer or additives.

Cat grass does not need much fertilizer anyway since it won’t last long.

You can also mix some perlite or vermiculite into the soil to improve drainage and aeration.


Choose safe and nutritious seeds for cats, such as wheat, barley, oats, or rye.

You can also mix different types of seeds to create a variety of textures and flavors for your cat.

Make sure the seeds are fresh and organic.

How To Care for Cat Grass?

Once you have grown your cat grass, you need to take care of it to keep it healthy and fresh for your cat.

Cat grass does not require a lot of maintenance, but there are some things you should do to ensure its quality and longevity.

Here are some tips on how to care for cat grass.

Trim It Regularly

To prevent the cat grass from becoming too long and floppy, trim it at least one inch every other week.

This will also encourage new growth and keep the grass green and tender.

Remove Dead or Yellow Leaves

As the cat grass grows, some leaves may die or turn yellow.

You should remove these leaves as soon as you notice them to prevent mold and decay.

You can use scissors or your fingers to pluck them out.

Check for Pests or Mold

Cat grass can attract pests, such as aphids or spider mites, or develop mold, especially if it is overwatered or kept in a humid place.

You should check your cat grass daily for any signs of pests or mold and discard it if you find any.

Do not use pesticides or fungicides on your cat’s grass, as they can harm your cat.

Resow Your Cat Grass Seeds

Cat grass does not last forever. It will eventually become old or wilted and lose its nutritional value and appeal for your cat.

You should resow your cat grass seeds every two to four weeks, depending on how fast your cat eats it.

You can use the same container and soil or start a new one.

Possible Problems With Cat Grass

While cat grass is generally safe and beneficial for most cats, some potential problems may arise from growing or feeding cat grass to your cat.

Here are some of the common issues and how to avoid them.

Allergic Reactions

Some cats may be allergic to certain types of grasses or seeds and may experience symptoms such as itching, sneezing, or swelling.

If you notice any signs of an allergic reaction in your cat, stop offering cat grass and consult your veterinarian.

Vomiting or Diarrhea

Cat grass can induce vomiting or diarrhea in some cats, especially if they eat too much or too fast.

This can cause dehydration or electrolyte imbalance in your cat.

To prevent this, limit the amount and frequency of cat grass you give your cat and ensure they have access to fresh water at all times.

Choking or Damage

Cat grass can cause choking or damage to your cat’s throat or digestive tract if they swallow large pieces or sharp edges of the grass.

This can lead to bleeding, infection, or obstruction in your cat.

To prevent this, trim the cat grass regularly and remove any dead or yellow leaves.

Also, monitor your cat when they eat cat grass and seek veterinary attention if they show signs of distress.

Parasites or Diseases

Cat grass can harbor parasites or diseases that can infect your cat, such as worms, bacteria, or fungi.

This can cause illness or complications in your cat.

To prevent this, buy or grow organic cat grass free of pesticides or herbicides.

Also, check your cat grass daily for pests or mold and discard it if you find any.


Cat grass is a beautiful way to enrich your cat’s life and health.

Always consult your veterinarian before introducing cat grass to your cat’s diet, and monitor your cat’s response to it.

Cat grass is not a substitute for balanced and complete cat food but a supplement that can enhance your cat’s well-being.
