Cat Grass vs. Catnip

Sure, all cat owners—and even those without cats—have heard about catnip. It has been a staple in the cat world for what seems like an eternity. Once upon a time, it was even believed to help humans with ailments.

You might think cat grass is just another name for catnip. After all, it’s clearly a plant for cats. This isn’t the case—it’s entirely different. So, what makes these two cat-friendly plants stand apart? Let’s get to know each one a little better.

Overview of Catnip

Catnip is extremely popular among the feline population for its feel-good qualities. Although catnip is a plant that freely grows in most environments, it can also come in dried, spray, or essential oil form.

You can find catnip littering the cat product section of any local or online pet store. Manufacturers make toys, treats, and sprays with catnip for your feline’s leisurely pleasure.

Maybe your cat isn’t much of a catnip candidate. Have you ever given your cat a toy or spray of catnip only to notice no change? It’s not your imagination. Some kitties, as we will learn later, are immune to the effects.

Overview of Cat Grass

When you hear cat grass, you may dismiss it as just another term for catnip, but this isn’t the case. It’s just regular grass that companies set up for you to grow indoors—kind of like a Chia Pet.

Some kitties love to chew on plants. Others may have an issue with hairballs. Companies designed cat grass containers that you self-grow indoors just for your felines to chomp on. It’s ordinary grass without any added chemicals or additives that can hurt your beloved pet.

Just consider cat grass a mixtape of ordinary grasses including wheat grass, oat grass, barley grass, and rye grass single or combined for your feline’s munching pleasure.

All About Catnip

Catnip goes by many names like catwort, catmint, and scientifically, Nepeta cataria. It’s actually one of the over 600 mint plant varieties and hybrids. It was used in traditional medicine for eons, so it wasn’t just valuable to our furry friends.

Catnip was introduced to America in the 18th century and was a feline favorite ever since. While it works great for most, you may find it surprising that not all cats have the same reaction to its compounds.

Is Catnip a Drug?

In a sense, catnip is like a drug for cats. It changes the brain and momentarily alters behavior for roughly 20 minutes. There is a part of catnip that is tantalizing to a cat’s sensory. It’s called nepetalactone. When nepetalactone binds to receptors in your cat’s nose, it activates a sensory response in the amygdala and hypothalamus. This triggers behaviors such as rolling, rubbing, “zoomies,” purring, or even staring at “something”..

However, it is non-toxic and non-addictive. Its effects are short-lived, lasting only 5-15 minutes, after which the cat becomes immune. A break is needed for the effects to reoccur.

Interestingly, showing signs of catnip exposure is hereditary and doesn’t show up in kittens until after at least 3 months of age. An estimated total of 30-40% of cats have no reaction when they are exposed to catnip.

Is Catnip Safe?

Catnip is very safe for cats. At worst, if your cat is exposed to larger amounts of catnip, it can cause irritation or general upset. And you may have one of the 30-40% of cats that has no reaction or change in behavior at all.

Can Cats Overdose?

No, cats can’t overdose on catnip. However, if they eat too high of a dose, it can lead to some not-so-pleasant side effects like nausea or diarrhea.

All About Cat Grass

Cat grass is a blend of many kinds of grass grown from seeds. You grow this grass indoors, making it different from lawn grass where there aren’t chemicals, and the grass types are specific.

For most kitties, cat grass can be an excellent alternative to harassing common houseplants. There are some other benefits, too.

Is Cat Grass Safe?

Cat grass is perfectly safe for your feline. It puts roughage in their diet and keeps them from chewing on potentially toxic plants. It’s far better to get them some cat grass to chew on rather than having them eat a dangerous plant in your home.

Remember to always consult a vet before introducing anything new to your cat’s environment. You can always consult a vet online.

Can Cats Digest Cat Grass?

Cats are obligate carnivores, so you might wonder if they can digest cat grass. Some cats will actually regurgitate the grass, and some will show no interest at all. If they do eat it, it can act as a laxative to clear out their system.

It’s a pretty widespread idea in the pet owner world that our furry friends only eat grass when they have an upset stomach. However, some cats just enjoy munching on it.

How Long Does Cat Grass Live?

The life of cat grass depends on many factors. Standard containers that come with cat grass only allow the grass to live for a short time, typically less than 6 weeks.

However, if you plant your cat grass in a deep pot where the roots can take hold, one batch can last several months.
