3 Things to Know About Cat Grass Before Giving it to Your Cat

Is cat grass tastier to your cat than your prized philodendron (RIP)? Will it help you save your plants? Is cat grass safe?

The short answer is yes, yes and yes but there’s more to the story. 

Mia (my cat) loves plants and as you are reading this article, I imagine you’ve probably caught your feline friend munching on houseplants or backyard grass too...

Did you know there’s a safer, healthier alternative called cat grass?

Let’s explore why cats love it, how it benefits them (backed by science!), and what you need to know before introducing it to your pet.

Why Do Cats Eat Grass? The Surprising Reason!

Cat grass isn’t just any random patch of greenery. It typically refers to a mix of grasses such as wheatgrass, barley, oat, or rye. Unlike the grass in your yard (which may have seen better days, I don't judge), cat grass is grown specifically for feline consumption and is free from harmful pesticides or fertilizers.

So why do cats eat it? While cats are obligate carnivores, meaning they thrive on meat-based diets (they're basically tiny lions, after all), they occasionally enjoy munching on plants. Some theories suggest that cats instinctively eat grass for its fiber content, which aids digestion and helps expel hairballs.

Others believe it’s simply an enjoyable sensory experience—like a salad bar for your kitty...if salad bars also involved occasional projectile vomiting (more on that later).

But why do cats eat grass in the first place? The main dominating theories include:

• Digestive aid: Grass contains fiber, which helps move things along in your cat’s gut. The fiber acts as a gentle laxative, helping to clear the digestive tract.
• Hairball control: It may help cats pass hairballs naturally instead of hacking them up. Veterinarians believe the fiber in cat grass can bind to hair in the stomach, facilitating its passage through the digestive system.
  
• Nutritional boost: Some experts believe grass provides trace vitamins or minerals. Cat grass, particularly wheatgrass, contains small amounts of vitamins A, C, and E, as well as folic acid. 
• Instinct: Wild cats eat grass, too! It might just be in their DNA. Some researchers propose that the instinct to eat grass is a holdover from their wild ancestors who consumed whole prey, including the indigestible parts like bones and fur.

When I first introduced outdoors to my cat Bengal, Mia, she sniffed grass suspiciously before taking a cautious bite. Within seconds, she was hooked—chewing happily like it was the best thing ever. But then…she threw it up! At first, I panicked, but after some research, I realized this was completely normal (and a sign I should probably invest in a better vacuum).

If you're introducing cat grass to your pet for the first time, here’s a useful guide on cat training that might help.

Is Cat Grass Safe for All Cats, Including Kittens?

For the most part, yes, cat grass is safe for all cats, including kittens. However, there are a few precautions to keep in mind:

Introduce Gradually

If your cat has never tried cat grass before, start slow. This helps you monitor their reaction and ensures they don’t overindulge.

Avoid Overeating

While safe, too much of a good thing can upset your cat’s stomach and will induce vomiting. Mia often eats it until she vomits (which I never know if it's her intention altogether).

I often let her limit herself but if I am on a roadtrip or will go indoors soon after, I stop her to avoid accidents and messes.

Check for Allergies

Though rare, some cats may have sensitivities to certain types of grass. Always consult your vet if you notice unusual symptoms.

For kittens, cat grass can be a great way to introduce them to safe chewing habits while keeping them away from toxic houseplants (bye-bye, precious lilies!), it’s especially important to watch for overconsumption. 

Tiny digestive systems can be sensitive, so let them nibble a little at a time.

Why Does Your Cat Eat Grass—Only to Throw It Up?

Ah, the age-old mystery: why does your cat eat grass only to vomit it back up? While it might seem alarming, this behavior is usually harmless. Grass acts as a natural emetic (something that induces vomiting), helping cats expel indigestible materials like fur or bones they might have swallowed.

Think of it as nature’s way of giving your cat a little digestive reset. However, if vomiting becomes frequent or excessive, consult your veterinarian to rule out underlying health issues.

Myth vs. Fact: Tummy Troubles Edition!

Myth: My cat barfing up grass means they're clearly plotting my demise!
Fact: They’re just decluttering their stomach—blame the furballs, not your cat’s vendetta.

Is Cat Grass the Same as Regular Grass? Understanding the Difference

Not all grass is created equal. The stuff in your yard is not the same as cat grass.

Regular lawn grass may contain (particularly if it's not your own lawn):

• Pesticides and herbicides

• Harmful fertilizers

• Tough, indigestible blades

Cat grass, on the other hand, is:

• Grown specifically for cats

• Soft, easy to chew, and digestible

• Free from toxic chemicals

Letting your cat snack on backyard grass is good, but it involves more risk than providing a controlled and safe alternative indoors. When I can, I stick to cat grass to keep her safe.

Many cat owners wonder if grass can be a good supplement to their cat's diet. While cat grass has benefits, it's important to ensure your cat gets proper nutrition. Here’s a complete guide on feeding cats to help you make informed choices.

How Does Cat Grass Help with Digestion and Hairballs?

Hairballs are the price our cats pay for being so clean. But cat grass may help reduce hairballs by keeping digestion moving smoothly.

• Fiber boost: The high fiber in cat grass helps move hairballs and other indigestible materials through the digestive tract by adding bulk to the stool and stimulating intestinal contractions. 
• Natural laxative: For constipated kitties, chewing on cat grass can act as a mild laxative due to its high fiber content. 
• Folic Acid: Found in many types of cat grass (like wheatgrass), folic acid supports oxygen circulation in the bloodstream and overall health. Folic acid is essential for red blood cell production, which carries oxygen throughout the body.

Of course, cat grass isn’t a cure-all. 

If your cat suffers from frequent hairballs, adjusting their diet might also help. Check out these tips on balanced feline nutrition.

Pro Tip: If your long-haired kitty struggles with frequent hairballs, consider adding cat grass and regular brushing to their routine.

Can Cat Grass Replace Regular Cat Food?

Nope. Cat grass is great, but it’s not food.

While cat grass offers plenty of benefits, it’s not a substitute for regular cat food.

Cats are obligate carnivores and require specific nutrients like taurine and protein found only in animal-based diets. While cat grass has fiber and a few nutrients, it doesn’t provide the protein, fats, and essential vitamins cats need.

Think of it as a healthy snack, not a meal replacement. Your cat still needs high-quality wet or dry food to stay healthy. 

Cat grass is a great supplement, but it can't replace a well-balanced diet. If you're unsure about what to feed your cat, check out our complete guide on cat nutrition.

Myth vs. Fact: Dietary Delusions!

Myth: My cat is turning green; they're evolving into a plant-based superhero!
Fact: They're still a carnivore with a refined palate for chicken, fish, and maybe a tiny bit of grass.

Common Cat Grass Problems and How to Fix Them

Grass is turning yellow? Too much water or not enough light. Adjust as needed.

Mold growing in the soil? Increase air circulation and let the soil dry out slightly between waterings.

Cat isn’t interested? Try mixing a little into their food or placing it near their favorite nap spot. Some cats take time to warm up to it.

Walking on a Leash Outdoors: Even Better Than Cat Grass?

While cat grass is great, outdoor time on a leash is even better. It provides:

• Exercise – Helps burn off that zoomie energy.

• Mental stimulation – New smells, sights, and sounds.

• Safe outdoor experience – No risk of running off or getting lost.

A well-fitted cat harness is a must. If your cat has never worn one before, start slow and use treats to make it a positive experience. Read our guide on walking cats on a leash.
