Sure, you’ve seen your cat nibble on grass from time to time, but is it safe? Read on to find out whether cats can eat grass and if it offers any benefits.

What Cats Eat

Cats are obligate carnivores, which means that they require animal protein to survive. Their bodies are not designed to process plant matter. However, some cats do enjoy eating grass. It is not clear why they do this, but it is thought that it could be for one of the following reasons: to fulfill a nutritional need, to help with digestive problems, or simply because they like the taste.

Cats are obligate carnivores

Cats are obligate carnivores, which means that they require animal protein to survive. Cats are not able to properly digest plant matter, so it’s important to make sure that their diet consists mainly of meat.

While cats may occasionally nibble on grass, it’s not an essential part of their diet and should not make up a significant portion of their food intake. If you’re concerned that your cat isn’t getting enough greens in their diet, talk to your veterinarian about adding a supplement or switching to a food that contains more plant-based ingredients.

Cats eat small prey

Cats are obligate carnivores, meaning that they haven’t evolved to digest carbohydrates and they require animal protein to survive. In the wild, cats eat mostly small prey–likely because larger prey is more difficult to take down and because smaller prey is easier to eat in one sitting. Domestic cats don’t typically have to worry about hunting for their food, but their wild instincts still remain.

Many people believe that grass-eating is a behavior that cats display when they’re feeling ill, but this isn’t always the case. Some cats simply enjoy the taste of grass, while others may eat grass as a way of self-medicating if they’re feeling nauseous. If your cat is eating an abnormal amount of grass or if you notice them vomiting after eating grass, it’s important to take them to the vet as they may be sick.

Whether or not you should allow your cat to eat grass is up to you, but it’s generally considered safe. If you’re concerned about your cat’s health, talk to your vet about whether or not grass-eating is normal behavior for your pet.

Why Cats Eat Grass

Many people think that cats eat grass because they are sick or have an upset stomach. However, that is not the only reason why cats eat grass. Some cats actually like the taste of grass. It is also a good source of fibre for them. Cats may also eat grass to help them get rid of hairballs.

Some believe it is for hairballs

Hairballs are a common issue for cats, especially those that groom themselves frequently. It is believed by some that cats eat grass to help them with hairballs, as the grass acts as a natural laxative and can help them pass the hair through their system.

Some believe it is for indigestion

Although the jury is still out on why cats eat grass, there are some theories. One theory is that cats eat grass to help with indigestion or as a way to settle their stomachs if they are feeling nauseous. It is believed that the grass acts as a natural laxative and helps to move things along.

Another theory is that cats eat grass for added nutrients and vitamins that may be lacking in their diet. Cats are obligate carnivores, which means that their bodies are designed to digest and use only animal-based proteins. However, this does not mean that they do not benefit from other nutrients found in plants.

So, while we may not know definitively why cats like to nibble on grass from time to time, there are some plausible explanations. If you are concerned about your cat eating grass, make sure that the plant is safe for them to ingest and monitor them closely to make sure they do not start showing any adverse effects.

The Dangers of Cats Eating Grass

Cats may eat grass as a way to relieve an upset stomach. However, grass can actually be harmful to your cat and can cause vomiting, diarrhea, and other digestive issues. If you think your cat is eating grass to vomit, it’s best to take them to the vet to rule out any other health issues.

Pesticides and herbicides

While there are benefits to cats eating grass, there are also some dangers to be aware of. One of the main dangers is that grass may be treated with pesticides or herbicides that can be harmful to cats if ingested. It’s important to only allow your cat to eat grass from areas that are known to be pesticide and herbicide free. If you’re not sure, it’s best not to take the risk.

Another danger of cats eating grass is that they may ingest harmful toxins from certain plants. Some plants, such as lilies, can be deadly for cats even if only a small amount is ingested. If you have any plants in your home that could be harmful to Cats, make sure they are out of reach and not within easy swatting distance!


Fertilizers can be very dangerous to cats if they consume too much. Fertilizers contain a variety of chemicals that can be harmful to cats, including nitrogen, phosphorus, and potassium. These chemicals can cause stomach and intestinal upsets, vomiting, and diarrhea. In severe cases, they can lead to liver and kidney damage. If your cat ingests too much fertilizer, it is important to take them to the vet immediately.


Based on the available evidence, it appears that grass eating by cats is a normal behavior with potential benefits. If your cat is an outdoor cat, try to provide a safe area of grass for them to eat. If your cat is indoor-only, you may be able to grow grass or provide dried grass for them to eat.
