cat grass benefits for cats

Have you ever noticed your cat nibbling on grass?

If you have, you might have wondered why they do it and if it’s safe.

The good news is that this behavior is quite natural, and providing your feline friend with cat grass can be beneficial for their health.

In this post, we’ll dive deep into why cats eat grass, the benefits of cat grass, how to provide it safely, and when to consult a veterinarian.

Whether you’re a new cat owner or a seasoned pro, this guide will give you everything you need to know about cat grass and its benefits.

Why Do Cats Eat Grass?

Cats eating grass is a common yet puzzling behavior for many pet owners.

Understanding why cats do this can help us appreciate the benefits of providing cat grass.

Here are some key reasons behind this behavior:

Natural instinct

Cats are natural hunters.

In the wild, they eat all parts of their prey, including the stomach contents, which often have plants.

Eating grass might be a leftover instinct from their wild ancestors.

By munching on grass, domestic cats may be mimicking the plant-filled stomachs of their prey, maintaining a connection to their wild diet.

Digestive aid

Grass can help cats with digestion.

The fiber in grass acts as a natural laxative, helping food move smoothly through the digestive system.

This can be particularly useful if your cat is constipated.

The fiber in the grass helps bulk up the stool and makes it easier for the cat to pass it.

Regularly eating grass can help keep your cat’s digestive system healthy.

Nutrient boost

Grass contains essential nutrients like folic acid, which is important for producing hemoglobin.

Hemoglobin helps carry oxygen in the blood, keeping your cat energetic and healthy.

By eating grass, cats can get these important nutrients that might not be present in their regular food.

Inducing vomiting

Sometimes, cats eat grass to make themselves vomit.

This might sound alarming, but it can actually help them get rid of indigestible matter, such as furballs or feathers.

Cats groom themselves a lot and often swallow a lot of fur, which can form hairballs.

Eating grass can help cats vomit and get rid of these hairballs, preventing digestive blockages.


Benefits of Cat Grass for Cats

Cat grass can offer several benefits for your feline friend.

Let’s explore how it can improve your cat’s health and well-being.

Improved digestion

Cat grass is rich in fiber, which helps with digestion.

It ensures that food moves smoothly through your cat’s digestive system, preventing constipation and promoting regular bowel movements.

This is especially important for indoor cats, who might not get enough natural fiber in their diet.

By nibbling on cat grass, your cat can keep their digestive system healthy and avoid uncomfortable issues.

Hairball control

Cats groom themselves a lot, which often leads to the ingestion of loose fur.

This fur can accumulate in their stomach and form hairballs, which they usually vomit up.

This can be unpleasant for both the cat and the owner.

Cat grass can help your cat pass these hairballs more easily through their digestive system, making the process more comfortable.

The fiber in the grass helps move the hair along the digestive tract, reducing the number of hairballs your cat has to deal with.

Nutritional benefits

Cat grass is full of vitamins and minerals that can boost your cat’s health.

For example, it contains chlorophyll, which acts as a natural breath freshener and detoxifier.

Chlorophyll helps neutralize odors in your cat’s mouth and supports liver function, aiding in detoxification.

Cat grass also provides other essential nutrients that might be missing from regular cat food, making it a great natural supplement to your cat’s diet.

Mental stimulation

Eating grass can provide mental stimulation for indoor cats, keeping them entertained and mentally active.

Indoor cats often lack the natural hunting and exploring activities that outdoor cats enjoy.

Providing cat grass gives them something interesting to explore and chew on, which can help prevent boredom.

Boredom can lead to behavioral problems like excessive meowing or scratching furniture, so keeping your cat mentally stimulated is important.


Grass has a high moisture content, which can help keep your cat hydrated.

Good hydration is crucial for your cat’s overall health, but some cats are not big water drinkers.

By chewing on grass, they can get some additional water, which helps keep their kidneys and urinary tract healthy.

This is particularly beneficial for cats prone to urinary tract issues.


How to Provide Cat Grass Safely

Cat grass can be a great addition to your cat’s life, offering numerous health benefits.

To make sure your cat enjoys it safely, here are some detailed tips:

Choose the right grass

Make sure you buy grass specifically grown for cats, often labeled as “cat grass.”

Common types include wheatgrass, oat grass, barley, and rye.

These varieties are safe for cats to eat and provide excellent nutritional benefits.

Grow your own

Growing your own cat grass ensures that it’s fresh and free from harmful chemicals.

You can find cat grass kits at pet stores or online, which usually include seeds and soil.

This is a fun and rewarding project, and you’ll have peace of mind knowing exactly what’s in your cat’s grass.

Use organic soil

If you’re growing cat grass at home, use organic soil.

Non-organic soils might contain chemicals and fertilizers that could harm your cat.

Organic soil ensures that your cat isn’t exposed to any potentially dangerous substances while enjoying their grass.

Provide in moderation

While cat grass is good for your cat, too much can cause digestive issues.

Start by placing a small pot of grass where your cat can access it, and monitor how much they eat.

If they seem to be overeating, limit their access to prevent any digestive problems.

Finding the right balance is key.

Maintain cleanliness

Keeping the cat grass clean is essential.

Make sure it’s free from mold and contaminants.

Water it just enough to avoid mold growth, and check it regularly for signs of spoilage.

Replace the grass as needed to ensure it stays fresh and healthy.

A good rule of thumb is to provide a fresh pot every couple of weeks.

Placement and safety

Put the cat grass in a spot where your cat can easily reach it, but where it won’t get knocked over or contaminated.

A stable surface in a well-lit area works best.

Also, ensure other pets or children don’t interfere with the grass to keep it clean and safe for your cat.


When to Consult a Veterinarian

Cat grass is generally safe and beneficial for most cats, but there are times when you should reach out to your veterinarian to ensure your cat stays healthy.

Here are some situations where veterinary advice is important:

Excessive vomiting

It’s normal for cats to vomit occasionally after eating grass to expel hairballs or other indigestible materials.

However, if your cat is vomiting frequently, it might indicate a more serious issue.

Excessive vomiting could be a sign of gastrointestinal problems, such as an obstruction or infection.

If your cat keeps vomiting, it’s important to consult your veterinarian to find out what’s wrong and get the right treatment.

Digestive problems

While cat grass can help with digestion, prolonged issues like diarrhea or constipation shouldn’t be ignored.

Diarrhea can lead to dehydration, while constipation can cause discomfort and serious complications if left untreated.

If your cat has ongoing diarrhea or constipation despite eating cat grass, it’s crucial to seek veterinary advice.

Your vet can identify the cause and recommend the best treatment to resolve the issue.

Behavioral changes

Sudden changes in your cat’s behavior, like increased lethargy, loss of appetite, or changes in grooming habits, should be taken seriously.

These changes can signal underlying health problems.

For example, a loss of appetite could indicate dental issues, gastrointestinal problems, or other illnesses.

Increased lethargy might be due to pain, infection, or other health concerns.

If you notice significant behavioral changes in your cat, it’s best to consult your veterinarian to rule out any serious conditions.

Allergic reactions

Although rare, some cats might be allergic to certain types of grass.

Symptoms of an allergic reaction include itching, redness, swelling, or even breathing difficulties.

If you notice any of these signs after your cat has been in contact with cat grass, consult your veterinarian immediately.

Allergies can be uncomfortable and sometimes dangerous for your cat.

Your vet can recommend alternative plants or treatments to help alleviate the symptoms.



Cat grass can be a wonderful addition to your cat’s diet, providing numerous health benefits from improved digestion to mental stimulation.

By understanding why cats eat grass and how to provide it safely, you can enhance your pet’s well-being.

Always monitor your cat’s reaction to the grass and consult your veterinarian if you have any concerns.
