When it comes to pampering our feline companions, the list is endless: cozy beds, stimulating toys, premium food, and even the occasional treat.
But there’s one addition that’s often overlooked and yet incredibly beneficial for your cat’s health and happiness: cat grass. If you’ve ever seen your cat nibble on plants or grass, you might have wondered why. Could it be mere curiosity, or does it fulfill a deeper need?
In this article, we’ll uncover the secret benefits of cat grass, explore why your cat craves it, and share tips on introducing this green delight into your home. Let’s dive in and discover why this simple plant is a must-have for your feline friend.

What Is Cat Grass?
Cat grass refers to specific types of grasses that are safe and beneficial for cats to eat. Common varieties include wheatgrass, oat grass, rye, and barley. These grasses are easy to grow indoors and provide a safe, chemical-free alternative to outdoor plants that may be harmful to your pet.

Unlike houseplants, which can sometimes be toxic, cat grass is grown specifically for your feline’s enjoyment and well-being. It’s important to note that cat grass is different from catnip; while catnip triggers playful or euphoric behavior due to its active compound nepetalactone, cat grass serves a more nutritional and digestive purpose.
Why Do Cats Eat Grass?
The sight of a cat eating grass might seem odd at first. After all, cats are obligate carnivores, meaning their primary diet consists of meat. However, there are several reasons why your feline friend might be drawn to nibbling on greens:
Digestive Aid: Cat grass can help with digestion by inducing vomiting to expel hairballs or other indigestible materials. This natural behavior helps prevent blockages in the digestive tract.
Nutritional Boost: Grasses for cats are rich in essential nutrients like fiber, folic acid, and vitamins. These nutrients can support overall health, including better digestion and oxygen transportation in the blood.
Instinctual Behavior: Cats in the wild often eat grass as part of their natural instincts. It’s believed that this behavior helps cleanse their system or make up for missing elements in their diet.
Curiosity and Enjoyment: Some cats simply enjoy the texture and taste of grass. The act of chewing can also be mentally stimulating and provide a fun activity for your indoor cat.

The Secret Benefits of Cat Grass
1. Improved Digestion
One of the primary benefits of cat grass is its role in aiding digestion. The high fiber content helps regulate your cat’s digestive system, preventing issues like constipation. Additionally, if your cat ingests something it shouldn’t have, such as a piece of string or plastic, the grass can help it pass through their system more easily.
2. Natural Hairball Remedy
Indoor cats often groom themselves excessively, leading to the accumulation of hair in their stomach. Cat grass acts as a natural hairball remedy by either helping cats vomit the hairballs or enabling them to pass through the digestive tract. This can reduce the frequency of hairballs and make your cat more comfortable.

3. Boosts Immunity
Grasses for cats, such as wheatgrass, are loaded with vitamins A, C, and E. These antioxidants support a strong immune system, keeping your cat healthier and more resistant to illnesses. The chlorophyll found in cat grass also has detoxifying properties, which can help cleanse your cat’s system of toxins.
4. Stress Relief and Enrichment
Providing cat grass indoors can offer mental stimulation and stress relief for your feline friend. Chewing on grass gives indoor cats an opportunity to engage in a natural behavior, which can reduce anxiety and boredom. This is particularly beneficial for cats with limited outdoor access.

Chewing on cat grass can promote better dental hygiene by naturally cleaning your cat’s teeth and gums. While it’s no replacement for regular dental check-ups, it’s a simple way to support oral health.
6. Hydration Support
Cat grass contains a significant amount of water, which can help keep your cat hydrated. This is especially useful for cats who don’t drink enough water on their own.
