What Are Cats Lacking When They Eat Grass?

Cats are fascinating creatures that bring joy to our lives. Their playful antics, purring, and cuddles can brighten even the darkest of days. However, one thing that often leaves cat owners scratching their heads is their furry friend’s love of grass. It may seem strange to us humans, but this behavior has been documented for centuries. So, what could be driving your cat to munch on greens?

If you’re a cat owner, chances are you’ve caught your feline friend chomping on blades of grass outside or perhaps even provided them with a patch of cat grass indoors. While some experts believe cats eat grass just because they enjoy it, there’s more to the story.

In this blog post, we’ll explore the reasons behind why cats eat grass and what nutrients they may be lacking in their diets that are leading them to do so. We’ll dive into the nutritional benefits of grass and explain why it’s essential for your kitty’s health. So buckle up and let’s uncover the mystery behind your cat’s green obsession.

What Do Cats Gain from Eating Grass?

Contrary to popular belief, there are several benefits that cats can reap from this behavior.

Firstly, cats may eat grass to assist in digestion. The fiber found in grass can help move food through a cat’s digestive system, which can be especially helpful when a cat is experiencing constipation or other digestive issues. Additionally, the act of chewing on grass can stimulate a cat’s appetite and encourage them to eat more.

Another advantage of eating grass is that it helps cats expel hairballs. As cats groom themselves regularly by licking their fur, hairballs can form in their digestive tract. Eating grass can help cats vomit up these hairballs and provide relief from any discomfort or irritation they may be experiencing.

Moreover, some experts think that cats may also consume grass to supplement their diet with additional nutrients. While cats are obligate carnivores and should primarily consume meat-based diets, grass contains vitamins A and D as well as chlorophyll, which can be beneficial for a cat’s overall health.

However, it is important to note that not all cats should be allowed to eat grass. Some cats may be sensitive or intolerant to certain types of grass or plants, which can cause digestive issues or even toxicity. Therefore, it is crucial to consult with your veterinarian before allowing your cat to graze on grass or other plants.

Why Do Cats Eat Grass?

After conducting research on the matter, it turns out that there are several reasons why cats eat grass.

Firstly, cats may eat grass to aid in their digestion. The fiber in grass stimulates the digestive system and helps pass hairballs through their system. This is especially important for cats that groom themselves frequently and ingest a lot of their own fur.

Secondly, some types of grass contain folic acid, which is beneficial to a cat’s health. Folic acid helps with the production of hemoglobin in the blood, which carries oxygen to cells throughout the body. So, it’s possible that cats eat grass as a form of self-medication.

Lastly, experts believe that cats may simply enjoy the texture and taste of grass. Eating grass can provide some variety in their diet and satisfy their natural urge to chew on things.

It is important to note that before letting your cat roam in a field of grass, consult with your veterinarian first. While it is generally safe for cats to eat grass, ensure that the grass they are consuming has not been treated with potentially harmful chemicals.

Is It Safe for Cats to Eat Grass?

The answer is generally yes, but there are some important things to keep in mind.

Let’s start with why cats eat grass. It’s not entirely clear, but many experts believe that it serves a few purposes. For one, grass is a natural source of fiber that helps with digestion and can even act as a natural laxative for cats. Additionally, some cats just seem to enjoy the taste of grass – like how we might enjoy certain foods.

However, not all types of grass are safe for cats. Some common household plants, such as lilies, tulips, and daffodils, are toxic to cats and can cause serious health issues if ingested. This means that it’s crucial to ensure that the grass your cat is eating is non-toxic and free from any harmful chemicals or pesticides.

So how can you ensure that your furry friend is consuming safe grass? One option is to grow your own cat grass indoors. This way, you can control what types of seeds are used and ensure that the grass is grown without any harmful chemicals or pesticides. Alternatively, if you let your cat roam outside, make sure they only have access to grass that you know is safe.

It’s also important to monitor your cat’s behavior after they’ve eaten grass. While it’s generally safe, some cats may experience vomiting, diarrhea, or other digestive issues after eating it. If you notice any unusual symptoms or your cat consistently vomits after eating grass, it’s best to consult with a veterinarian to rule out any underlying health issues.

Nutritional Benefits of Grass for Cats

Cats are notorious for their love of grass, from rolling around in it to nibbling on it. While some may worry about the potential dangers of ingesting grass, such as pesticides or toxins, there are actually some nutritional benefits to this behavior.

One of the primary benefits of grass for cats is its fiber content. Fiber is crucial for regulating digestion and promoting healthy bowel movements, which can be especially important for cats who suffer from constipation or hairballs. By eating grass, cats can supplement their diet with this essential nutrient.

In addition to fiber, grass contains a variety of vitamins and minerals that can be beneficial for cats. For example, vitamin E is an antioxidant found in grass that can help support immune function and protect cells from damage. Grass also contains small amounts of vitamin C, potassium, calcium, and iron, all of which contribute to a healthy feline diet.

Another interesting benefit of grass for cats is its chlorophyll content. Chlorophyll is a pigment found in plants that gives them their green color. It has been shown to have some antibacterial properties and may even help promote wound healing. Furthermore, some pet owners believe that chlorophyll can freshen their cat’s breath.

While cats do not require grass to meet their nutritional needs, adding it to their diet can offer some potential benefits. However, it is vital to ensure that any grass your cat eats is free from pesticides or other harmful chemicals. Additionally, if your cat regularly eats grass and experiences digestive issues or other health problems, it is crucial to consult with a veterinarian to rule out any underlying health conditions.

The Role of Fiber in Cat Nutrition

Not only does it regulate bowel movements and prevent constipation, but it also promotes weight management and reduces the risk of diseases like diabetes and heart disease.

Grass is a popular source of fiber for cats, but why is it so great? This humble plant contains two types of fiber: insoluble and soluble. Insoluble fiber adds bulk to stool, promoting regular bowel movements and preventing constipation. This type of fiber is especially important for cats because they are prone to hairballs and other digestive issues. Soluble fiber, on the other hand, forms a gel-like substance in the digestive system that slows down the passage of food. This can help cats feel full for longer periods of time and prevent overeating.

While grass may provide some fiber benefits for cats, it should not be relied upon as the sole source of this important nutrient. A balanced diet that includes adequate amounts of fiber is key to supporting their digestive health and overall well-being.

It’s important for cat owners to ensure their furry friends are getting the right amount of fiber in their diet. Too much or too little can lead to digestive problems like diarrhea or constipation. If you are unsure about how much fiber your cat needs, consult with your vet.

In addition to its digestive benefits, fiber can also improve overall health by lowering cholesterol levels and reducing the risk of certain diseases such as diabetes and heart disease. Therefore, it’s important to prioritize fiber in your cat’s diet.

Hairball Control and Cats Eating Grass

While this behavior may seem harmless, it can indicate an underlying health concern. One of the most common reasons why cats eat grass is to aid in hairball control. Hairballs are a common issue among cats, and eating grass can help them alleviate the problem. But there are other reasons why cats eat grass, too.

For starters, some cats eat grass to aid their digestion or as a form of self-medication when they have an upset stomach. However, if your cat is frequently eating grass and vomiting afterward, this may indicate an underlying digestive issue that requires medical attention. It’s always better to be safe than sorry, so don’t hesitate to consult with your veterinarian if you notice any concerning behavior or symptoms.

Furthermore, some studies suggest that cats may eat grass due to a lack of certain nutrients in their diet. As obligate carnivores, cats need a diet rich in meat-based protein. However, some commercial cat foods may not provide all the necessary nutrients for optimal health. If your cat lacks fiber in their diet, they may turn to eating grass as a source of fiber. Similarly, if they lack certain vitamins or minerals, they may try to supplement their diet by eating grass.

So, what can you do as a responsible cat owner? First and foremost, monitor your cat’s behavior and ensure they’re not trying to alleviate an underlying health issue. Secondly, ensure that your furry friend has a balanced diet with all the necessary nutrients to reduce the likelihood of them eating grass excessively.

Here are some tips to keep in mind:

  • Provide your cat with high-quality food that meets their nutritional needs.
  • Offer your cat occasional treats that contain fiber, such as small pieces of cooked vegetables or fruits.
  • Keep your cat indoors and away from potentially harmful plants or pesticides.
  • Consider providing your cat with a designated grassy area indoors, such as a planter filled with cat grass, to satisfy their natural instinct to nibble on greens.

Potential Risks of Eating Grass for Cats

While it may seem like a harmless and natural behavior, it’s crucial to know the potential risks of eating grass for cats. As an expert on this topic, I’ve gathered some research notes to help you keep your cat safe and healthy.

First and foremost, the grass that cats consume might have been treated with pesticides or other chemicals that can be harmful to their digestive system. Exposure to these chemicals can lead to severe health issues. It’s imperative to ensure that any grass your cat eats is from a safe source that is free from harmful chemicals.

Moreover, if the grass is not properly washed, it can carry bacteria and parasites that may cause illness in cats. Therefore, it’s essential to make sure any grass your cat eats is clean, fresh and free from these harmful agents.

Another risk of eating grass is intestinal irritation or blockages. Cats are not able to fully digest the fibrous material in grass, which can cause blockages in their digestive tract leading to vomiting, diarrhea or even more severe health issues if left untreated. So, it’s vital to monitor how much grass your cat consumes and ensure they do not eat too much.

Furthermore, just like humans, cats can develop allergies to grass. Allergic reactions can cause skin irritations, respiratory issues and other symptoms. Therefore, it’s essential to watch for any allergic symptoms in your cat after they have eaten grass.

As a responsible pet parent, it’s crucial to monitor your cat’s behavior when they eat grass and only allow them to consume safe and clean sources. If you notice any concerning symptoms after your cat has eaten grass, it’s best to consult with a veterinarian as soon as possible.

How to Make Sure Your Cat is Getting Enough Nutrients

One of the ways to achieve this is by ensuring that they are getting enough nutrients in their diet. Here are five sub-sections that will help you make sure your cat is getting all the nutrients they need.

Understand the Nutritional Needs of Cats

Cats are obligate carnivores, which means that their diet should consist mainly of animal protein. This is because they require certain nutrients, such as taurine, arginine, and arachidonic acid, which are found only in meat to survive. Without these nutrients, cats can develop serious health issues such as blindness, heart problems, and skin disorders. Therefore, it’s essential to understand what your cat needs and how to provide it.

Choose a High-Quality Cat Food

When it comes to choosing a cat food, look for brands that list meat as the first ingredient. Avoid those that contain fillers such as corn or soy. A well-balanced diet is essential for your cat’s overall health and well-being. A good quality cat food will provide your cat with all the essential nutrients they need to thrive.

Add Supplements to Their Diet

In addition to high-quality cat food, consider adding supplements such as omega-3 fatty acids or probiotics to your cat’s diet to support overall health. Omega-3 fatty acids can help reduce inflammation and improve joint health, while probiotics can help support healthy digestion. However, before adding any supplements to your cat’s diet, consult with your veterinarian.

Monitor Your Cat’s Grass Eating

While it is generally safe for cats to eat grass in small amounts, it is important to monitor them and ensure they’re not consuming any potentially harmful plants or pesticides. If you notice excessive vomiting or other signs of illness after your cat has eaten grass, seek veterinary attention immediately. Feeding your cat a well-balanced diet that meets their nutritional needs can reduce their desire to eat grass.

Consult with Your Veterinarian

If you have concerns about your cat’s diet or nutritional needs, consult with your veterinarian. They can provide you with recommendations on how to meet your cat’s specific dietary needs. Your veterinarian can also advise you on the appropriate supplements to add to your cat’s diet to support their overall health.


In conclusion, cats have been munching on grass for centuries, and it’s a natural behavior that serves a purpose. While some experts believe that cats eat grass for the taste and texture, there are several reasons why they indulge in this habit. One of the primary reasons is to aid digestion and hairball control. Grass contains fiber that helps move food through a cat’s digestive system and can facilitate the expulsion of hairballs. Moreover, some types of grass contain folic acid, which is beneficial to a cat’s health.

However, not all types of grass are safe for our feline friends. Some plants can be toxic or treated with harmful chemicals. Therefore, it’s crucial to ensure that any grass your cat consumes is clean and free from harmful agents.

To reduce your cat’s excessive desire to eat grass, provide them with a well-balanced diet that meets their nutritional needs. Opt for high-quality cat food with meat as the first ingredient and consider adding supplements such as omega-3 fatty acids or probiotics to support overall health.

As responsible pet owners, we should monitor our furry friend’s behavior when they eat grass and consult with a veterinarian if we notice any concerning symptoms or behaviors. By understanding our cat’s nutritional needs and providing them with proper care, we can ensure they live happy and healthy lives without relying solely on grass consumption.

In summary, while cats may enjoy nibbling on blades of greenery now and then, it’s essential to make sure they’re getting everything they need from their diet so that they don’t rely too heavily on this behavior.
