What Does It Mean When Cats Eat Grass? Unraveling Feline Behavior

Cats love meat, but many cat owners have noticed that their feline friends sometimes nibble on the grass, which goes against their nature. For years, this unusual behavior has confused both pet owners and scientists and raised many questions. Does it aid digestion, or does it satisfy their taste buds? This article will unravel the myth and science behind this green treat for cats and “What exactly does it mean when cats eat grass?” Join us as we explore the reasons behind this behavior.

What Does It Mean When Cats Eat Grass

Why Do Cats Eat Grass Sometimes? | Reason Behind Cats Eating Grass?

Since cats are carnivores, the majority of their diet consists of meat. This is because carnivores mostly hunt against other animals. However, sometimes, you’ll see your cat grazing outside. Both house cats and big cats like lions have been observed engaging in this action. There exist several reasons why cats consume grasses.

Cats acquire the majority of their nourishment from meat because they are obligate carnivores and natural hunters. However, you will occasionally notice your cat munching on grass in the backyard. Both domesticated cats and big cats like tigers and lions have been observed to exhibit this behavior. There are several reasons why cats eat grass.

Nutritional Benefits of Grass for Cats

Cats consume grass to supplement their diet with vital elements. Although they must eat meat for survival, obligate carnivores can supplement their low mineral and vitamin intake by eating some plant food. Other B-vitamins found in grass, such as Folic Acid, are necessary in a cat’s body. These include niacin, which affects metabolism; vitamin K, which is useful for the blood clotting process as well as thiamine, used by the body to produce energy, amongst others. Furthermore, the pigment chlorophyll, which is very much present in the grass and enhances it with its antioxidant characteristics, makes it look greenish-yellow. Some experts claim that cats have an inherent knowledge of eating grass, which will provide fiber requirements, improve digestion, and drive bowel movements. Hence, indoor cats often chew leaves from plants despite the lack of vegetables in their diet.

Grass as a Natural Laxative for Cats

Cats eat grass to relieve themselves from digestive distress or to eject content by vomiting. Cats are known to be very cautious about their grooming, which may sometimes make them accidentally swallow hair, resulting in hairballs in their system. Eating grass can help them disgorge hairballs and other indigestible things causing discomfort. Furthermore, grass may benefit because of its natural laxative properties, which aid the digestive process. However, not all cats who eat grass vomit or have alterations in their bowel habits. This shows that cats’ responses to grass-eating may vary depending on the individual.

Soothing an Upset Stomach

When cats have an upset stomach, they sometimes seek out grass. Ingesting grass blades can trigger a cat’s vomiting reflex, which helps them expel uncomfortable items that are difficult to digest. While this may provide temporary relief, pet owners must ensure that vomiting does not repeat frequently, as it may indicate underlying health issues that require veterinary attention.

Self-Medicating Habit

Plant material consumption may aid in expelling internal parasites, benefiting the cat’s evolution and digestive health. This behavior has been recognized as a self-medicating mechanism to relieve the discomfort caused by parasite infections. Wild cats eat mostly raw meat, which makes them more prone to parasites. The natural tendency for domestic cats to do this may have evolved from a strategy for controlling pests. While domestic cats are less likely to acquire such infestations, especially with regular veterinarian care, the intrinsic propensity to consume grass may remain an evolutionary legacy.

Boredom and Mental Stimulation

If your cat has access to outside space, it could munch grass for fun or just because it is there. In addition to keeping them engaged and providing a welcome change of pace, chewing on grass blades helps stimulate their minds. Some cats may view this activity as a hobby because it gives them an opportunity to play and discover their surroundings. Indoor cats may also seek out houseplants or specially cultivated cat grass, indicating a desire for stimulation and sensory enrichment in their daily life.

Instinctual Behavior or Learned Response?

Cats are famous for their inquisitive nature. It’s possible that they’re just trying out different kinds of plants because they’re interested. Additionally, outside cats picked up this habit from their mothers or other cats. Regular grass consumption in cats can indicate a learned behavior, especially if they seek it out when not feeling well. However, there is still substantial controversy about whether this behavior is entirely innate or impacted by external influences.

Grass Tastes Good

According to some scientists, cats eat grass just because they enjoy the flavor and texture of it. Cats have diverse interests and preferences, just as humans. Some researchers believe grass contains catnip-like substances that, when swallowed, may provide cats with a delightful experience. Whatever the cause, it’s evident that grass is still an interesting and exciting component of cat behavior, contributing to their distinct and different personalities.

What Should I Do If My Cat Eats Grass?

Cats eating grass should not alarm you as this is normal for them, and as long as the grass is free from any poison or pesticides, it should be safe. However, suppose you find your cat eating grass continuously or having other symptoms such as vomiting, diarrhea, or lack of strength. In that case, you should contact a veterinarian who will diagnose these signs and eliminate some possible underlying diseases.

What Types of Grass Can Cats Eat?

Grass that cats eat should be free from any pesticides or other poisonous substances. Wheatgrass (Triticum aestivum) and oat grass (Avena sativa) are common types of indoor cat grass found in pet stores. Such plants provide good sources of nutrients for cats without causing harm to them. Alternatively, barley grass (Hordeum vulgare) does not contain toxins, making it beneficial to animals instead. Make sure you buy a product whose label certifies that no chemicals were used on it because this can otherwise be harmful to your feline friends. Moreover, cats should be slowly introduced to new varieties of these plant types so as not to upset their stomachs upon sudden change of diet.

Tips for Cat Owners

For cat owners looking to accommodate their pet’s grass-chewing habits safely, here are a few helpful tips:

  • Grow Your Own Cat Grass – Consider growing and keeping a small tray of cat grass indoors. This gives your cat access to a clean and safe source of grass.
  • Monitor Outdoor Eating Habits – Keep an eye on your cat outside to ensure they don’t consume grass from lawns that may have been treated with pesticides or herbicides.
  • Introduce Grass Gradually – – If your cat is not used to eating grass, gradually introduce it into their habitat to avoid digestive upset.
  • Offer a Balanced Diet – You should provide your cat with a balanced diet that includes all the nutrients it needs. Your cat may not need to hunt for grass or other supplemental food sources as much if this happens.
  • Provide Plenty of Water – Fresh, clean water should always be available. Proper hydration can aid digestion and may reduce the need for your cat to indulge in grass.
  • Regular Vet Check-Ups – Make sure your cat’s grass-eating habits don’t indicate a health problem by scheduling regular checkups with the veterinarian.


In summary, some pet owners may think it is strange or concerning when their feline pets eat grass, but the fact is that it is entirely normal and even beneficial for them. Understanding this behavior driven by instinct can assist cat parents in keeping a safe and healthy environment for their pets. Through adequate precautions and focusing on your cat’s needs, eating grass should not raise eyebrows; instead, it becomes an inbuilt biological urge toward better health. So, the next time you see your feline friend nibbling on some grass greens, know that it’s perfectly normal and part of being a cat. Keep an eye out for changes in your pet’s behavior or health, and always visit a veterinarian if you have any concerns about their well-being.
