What is Grass?

Grass, a ubiquitous plant found in diverse climates across the globe, is a member of the Poaceae family. Its defining features are its long, slender leaves that sprout from a central stem. With numerous species ranging from short and delicate blades to tall and sturdy stalks, grass thrives in nearly every environment.

Aside from its aesthetic appeal in landscaping, grass plays a crucial role in the ecosystem. It serves as a source of food and shelter for countless animals, including insects, birds, and small mammals. Additionally, humans have utilized grass for millennia as a source of sustenance for livestock and even as a playing field for sports.

Beyond its ecological contributions, grass offers nutritional benefits. Rich in soluble and insoluble fiber, it promotes gut health and can aid in weight management. Furthermore, grass contains various vitamins and minerals that can enhance overall health.

While grass may not seem like an obvious food choice for felines, some cats are inexplicably drawn to it. Some theories suggest that consuming grass can help cats digest their food or assist with regurgitating hairballs. However, pet owners must be vigilant as not all grasses are safe for cats to eat. Certain species such as Bermuda grass and crabgrass can cause gastrointestinal distress while foxtail grass can become lodged in a cat’s throat or intestines.

Why Do Cats Eat Grass?

One theory is that cats eat grass to aid in digestion. In the wild, cats eat their prey whole, including the stomach contents of their prey which often contain plant matter. Eating grass can help cats break down their food and aid in digestion. So if you notice your cat eating grass after a meal, it might be their way of helping their digestive system.

Another theory is that cats eat grass to help them expel hairballs. As we all know, cats are meticulous groomers and can ingest a lot of hair while grooming. This hair can accumulate in their stomachs over time, leading to the formation of hairballs. Eating grass may help to stimulate their digestive system and aid in the passing of hairballs.

Cats are also known for being curious creatures, and they may simply enjoy the taste and texture of grass. It’s not uncommon for cats to explore new tastes and textures, so it’s possible that they eat grass simply because they like it.

Interestingly, some experts suggest that cats may be attracted to the chlorophyll in grass as it can have a calming effect on their stomachs. Additionally, some cats may eat grass as a form of self-medication to address certain deficiencies or ailments.

While there is no definitive answer as to why cats eat grass, it is generally considered safe for them to do so in moderation. However, as a pet owner, it’s essential to be cautious as not all grasses are safe for cats to consume. Some plants can be toxic and cause harm to your feline friend.

Types of Safe Grasses for Cats to Eat

While this behavior is natural, not all types of grass are safe for cats to eat. Knowing which grasses are safe and beneficial for your feline friend is essential. Here are five types of safe grasses for cats to eat:


Wheatgrass is an excellent choice for cat owners because it’s easy to grow indoors and provides essential nutrients that promote overall health. It’s high in fiber, which can help with digestion, making it an excellent option for cats who experience digestive issues.

Oat grass

Oat grass is another indoor-grown option that can benefit your cat’s digestive system. It contains antioxidants that boost their immune system and can help regulate their digestive system.

Barley grass

Barley grass is packed with vitamins and minerals that can promote good health in cats. In addition to its nutritional benefits, it contains chlorophyll, which can help freshen their breath.

Rye grass

Rye grass is safe for cats to eat in small amounts, but too much can be difficult for them to digest. It’s best to offer rye grass as an occasional treat rather than a regular part of their diet.


While not technically a type of grass, many cats enjoy eating catnip. It’s safe for them to consume in moderation and can even have a calming effect on some cats.

It’s important to remember that outdoor grasses may have been treated with harmful chemicals, so it’s best to stick with indoor-grown or pet-safe options. If your cat experiences any unusual symptoms after eating grass, such as vomiting or diarrhea, consult with your veterinarian.

Benefits of Eating Grass for Cats

In fact, it’s quite beneficial for them. Let’s dive into the benefits of eating grass for cats.

Firstly, eating grass aids digestion in cats. While cats do not have the necessary enzymes to break down fiber, the fiber in grass can help with the movement of food through their digestive system. This means that a little nibble on some grass might just be the solution if your cat is experiencing digestive issues or constipation.

Secondly, grass provides essential nutrients to cats. Vitamins such as A and D, as well as minerals like calcium and potassium can be found in grass. These nutrients are vital for maintaining your cat’s overall health and well-being. Next time you see your cat munching on some grass, don’t worry, they’re just getting their daily dose of vitamins and minerals.

Furthermore, eating grass can also help relieve stress and anxiety in cats. Chewing on grass can help cats relax and feel calmer which is similar to how humans may chew gum or snack on comfort foods when feeling stressed. So if your cat seems anxious or restless, encourage them to nibble on some grass to help calm their nerves.

However, it’s important to note that not all types of grass are safe for cats to eat. Some types of grass can be toxic and cause harm to cats if ingested. As a responsible pet owner, ensure that the grass your cat is eating is safe and free from any harmful chemicals or pesticides.

In conclusion, while it may seem strange for cats to eat grass, it can actually provide several benefits for their health and well-being. As long as the grass is safe and free from any harmful chemicals, cat owners can encourage their feline friends to indulge in this natural behavior. So go ahead and grow some indoor grass plants for your cat to munch on – their health will thank you for it.

In summary, the benefits of eating grass for cats are:

  • Aiding digestion
  • Providing essential nutrients
  • Relieving stress and anxiety

Risks of Eating Grass for Cats

While it’s natural for cats to eat grass, there are some potential risks associated with this behavior that you should be aware of.

One of the biggest risks of cats eating grass is the ingestion of harmful chemicals. Grass that has been treated with pesticides, herbicides, or fertilizers can be toxic to cats if ingested. These chemicals can cause mild stomach upset or even more severe health issues like seizures and death.

Another risk is the possibility of your cat ingesting parasites or bacteria when eating grass. Outdoor cats can come into contact with harmful organisms that can make them sick if ingested. This could lead to gastrointestinal issues or other diseases.

Additionally, some types of grass can be difficult for cats to digest and may cause irritation or blockages in their digestive system. Long blades of grass can become wrapped around a cat’s tongue or stuck in their throat, ultimately leading to discomfort or requiring surgery.

Despite the risks, eating grass can provide some benefits for cats, such as aiding in digestion and eliminating hairballs. To keep your cat safe while still allowing them to enjoy these benefits, it’s important to monitor their grass intake and ensure they only eat safe options. Consider providing indoor plants or specially grown cat grass that is free of harmful chemicals and parasites.

How to Provide Safe Access to Grass for Your Cat

Cats are natural explorers, and they are often curious about their surroundings. One of the things that piques their interest is grass. Eating grass can provide some benefits for cats, such as aiding digestion and eliminating hairballs. However, not all types of grass are safe for cats to consume. Some grass may be treated with pesticides or fertilizers that can be harmful to cats. Therefore, it’s crucial to provide safe access to grass for your feline friend.

Growing Cat Grass Indoors

Growing cat grass indoors is one of the safest ways to provide your cat with access to grass. You can purchase seeds specifically designed for cats at most pet stores or online retailers. These seeds are typically a blend of wheat, oats, barley, or rye.

To grow cat grass, plant the seeds in a shallow container with potting soil and keep it in a sunny area of your home. Once the grass has grown to a few inches tall, you can offer it to your cat. However, make sure to monitor their behavior and ensure they are not consuming too much.

Using Pre-Grown Cat Grass

If you don’t want to grow your own cat grass, you can also purchase pre-grown cat grass from a pet store. This type of grass is already grown and typically comes in a small pot or container. You can place the container in an area where your cat has access to it, such as near their food or water bowls.

Pre-grown cat grass is convenient and requires minimal effort on your part. However, make sure to check the label and ensure that the grass is free from any harmful chemicals or pesticides.

Creating an Outdoor Enclosure

If you have space and resources, creating an outdoor enclosure for your cat is another way to provide safe access to grass. This will allow your cat to enjoy the outdoors safely and have access to natural grass. However, make sure to choose an area that is free from toxic plants and chemicals.

When creating an outdoor enclosure, ensure that it’s secure and escape-proof. Supervise your cat while they are outside to prevent them from eating any harmful plants or grass.

Using a Cat Grass Planter

A cat grass planter is another option for providing safe access to grass for your cat. These planters typically come with a cover that allows the grass to grow while keeping it safe from other pets or children. You can place the planter on a windowsill or balcony where your cat has access to it.

Cat grass planters are convenient and require minimal space. However, make sure to monitor the cleanliness of the planter and ensure that the grass is free from any potential hazards such as dirt or insects.

In summary, the age-old question of whether cats can eat grass is not a simple one to answer. While some experts argue that felines have a natural inclination towards consuming vegetation, others believe it’s purely for digestive reasons. Nevertheless, incorporating a small amount of plant material into their diet can be beneficial for most cats. Not only does it aid digestion and provide essential nutrients like vitamins A and D, calcium, and potassium, but chewing on grass can also help alleviate stress and anxiety in our furry friends.

However, there are potential risks associated with this behavior as well. Cats who ingest grass treated with pesticides or fertilizers could suffer from toxic poisoning. Outdoor cats may come into contact with harmful organisms that could make them ill if consumed. Moreover, certain types of grass may cause irritation or blockages in their digestive system.

To ensure your cat’s safety while still providing access to grassy greens, consider growing cat grass indoors or purchasing pre-grown options from pet stores. You could also create an outdoor enclosure or use a cat grass planter to keep your furry friend safe from harmful substances outside. It’s crucial to monitor your cat’s behavior and ensure they’re not overindulging in their green snacks.

As responsible pet owners, we must remain vigilant about the potential dangers associated with feeding our feline friends greens while acknowledging the benefits they receive when done safely and in moderation.
