Are you the proud owner of an indoor cat? Do you want to bring them some of the green outdoors indoors? Have you thought of growing your cat grass indoors?

Cats have an innate curiosity and tendency to nibble on anything green they can get their paws on. While this behavior is natural, it’s essential to be cautious, as some plants can harm your cat. Not only that but the pesticides and chemicals used in outdoor gardens can be hazardous for your cat.

Growing cat grass indoors gives your cat a healthy plant to chew on and provides a safe and enjoyable activity. I have grown cat grass for years and it sits on my balcony. My cats love it.

In this article, I’ll explore the benefits of cat grass and the best cat grass your house cat will love.

Purrfectly curious about cat grass? Let’s dig in!

What is Cat Grass?

Cat grass for indoor cats

Cat grass isn’t a specific kind of grass but rather a collection of grasses grown specifically for cats to chow down on. These grasses typically include:

  • Wheatgrass
  • Oat grass
  • Rye grass
  • Barley grass
  • Alfalfa

Whether you choose a single type or a mix of different grasses, these cat safe grasses are a great way to enable your indoor cat to practice their normal behavior. They can also help reduce the appeal of other house plants

Benefits of Cat Grass for Your Cat

Contrary to popular belief, cats don’t only eat grass when they’re sick. They may eat it to induce vomiting, settle upset tummies, and help clear out food or hairballs that make them uncomfortable. My cats usually eat their cat grass when they have hairballs and want to bring them up.

Cat grass also helps provide essential nutrients that may be missing from your cat’s diet, improve digestion, and reduce hairballs. It can be a source of vitamins, minerals, and fiber, contributing to your indoor cat’s overall health and well-being. Specific grass types, such as alfalfa, can even help treat kidney disease and reduce inflammation.

It can help reduce stress and boredom. Chewing on grass can provide indoor cats with a calming and enriching activity. It provides them with an interesting and engaging pastime that can prevent them from getting bored.

Interestingly big cats (think lions) use grass (and bones) to keep their teeth clean. Chewing on grass is thought to help prevent the build-up of plaque and tartar.

It also stops your cats from nibbling on your ornamental plants (which can be toxic to them), so you can have peace of mind knowing they’re eating something good for them.

Last but not least, the benefits of cat grass are that it is a safe and non-toxic alternative to other houseplants that may be harmful to your indoor cat. Read this article on cat-safe house plants for more info on this.

Just be sure to keep the grass and plants separated to avoid any confusion!

What Type of Cat Grass is Best for Cats to Eat?

Grass for cats to eat

When it comes to the best grass for cats, there’s no one-size-fits-all answer.

These finicky creatures may have their own paw-ticular preferences, but here are some top picks to keep your cat happy and healthy:

Oat Grass

Looking for a sweet and nutritious option for your feline friend? Oat grass may be just what you need.

This popular choice not only tastes great to cats, but it’s also packed with essential minerals, vitamins, and soluble fiber that aid digestion and promote a healthy digestive tract.

Plus, if your cat suffers from digestive issues, oat grass can help soothe its upset stomach.

Wheat Grass

Another top pick for cat grass is wheat grass. This highly nutritious option contains essential minerals and amino acids for your cat’s health.

One of the benefits of wheatgrass is its anti-inflammatory properties, making it an excellent choice for older cats who need help with arthritis. So to keep your feline friend healthy and happy, add wheatgrass to their diet and maybe yours too!


If you have a playful kitty who loves to roll around in the grass, ryegrass may be the perfect option. This short, durable grass can withstand even the roughest cat behavior and is ideal for active and playful cats.

While ryegrass isn’t necessarily the best choice for cats to eat, if you have an outdoor area and can create a path of grass it provides a fun and safe space for your feline friend to enjoy.

Barley Grass

Looking for a taller grass option that grows quickly and can stand up to your cat’s scratching and digging? Barley grass is a fantastic choice for cats who love to chew and scratch at their grass patches.


Finally, if your cat has chronic kidney disease or other renal issues, alfalfa may be the best option for them. Research has shown that alfalfa has numerous benefits for cats, and many veterinarians now recommend it as a dietary supplement. I really like this pack of heirloom seeds on Amazon which includes alfalfa, oat grass, cat grass mix and catnip.

How to Grow Cat Grass at Home

Best cat grass to grow

Get ready to flex your green thumb and give your kitty the gift of delicious, nutritious grass with these easy tips on growing cat grass at home!

You don’t need to be a gardening expert to make it happen – all you need is a shallow container, some soil, grass seeds, and a sunny spot to put it in.

You can use a spray bottle to moisten the soil to avoid overwatering and mold growth. And if you’re planting different types of grass, label the containers with chalkboard stickers for easy identification.

The seeds will sprout quickly, and the grass will last for a few weeks before you need to replace it.

But wait, it gets better! There are cat grass kits available that make the growing process a breeze.

Let’s look at the cat grass kits available to help you grow the purrfect grass for your indoor cat!

Planting Kits

If you’re new to growing cat grass, planting kits are an excellent choice. They come with everything you need to get started, including seeds, substrate, and containers. With planting kits, you won’t need to make any additional purchases, making them a convenient and cost-effective option. 

Follow the instructions, and you’ll grow fresh, tasty grass for your cat in no time!

Self-Growing Kits

Self-growing kits are a type of planting kit that uses a mini hydroponic system and doesn’t require soil. This makes them an attractive option if you don’t want soil in your home.

Self-growing kits are relatively low-maintenance, as they only require the addition of water. However, they need more care and monitoring than standard kits, so they may not be the best choice if you’re short on time.

Bulk Seeds

For more experienced gardeners, purchasing bulk seeds is a great option. This gives you the freedom to choose the specific type of grass you want to grow and to select containers that match your home decor.

Plus, buying seeds in bulk ensures that you always have a fresh supply on hand whenever you need to plant new cat grass.

Live Plants

If you’re not confident in your gardening skills or simply don’t have the time to grow cat grass from scratch, live plants may be the way to go.

While they can be more expensive than other options, live plants are already grown and ready to be enjoyed by your cat. Just be sure to choose a variety safe for cats and keep it where your cat can access it easily.

Where can you buy Cat Grass?

Cat grass is available to buy online from major marketplaces like Amazon and Chewy. I’ve put some suggestions below for you. Or I got my cat grass from my local pet store. I’ve also noticed pre-grown cat grass in my local garden center too – so try yours.
