The Fascinating World of Catnip: Effects on Cats and Kittens

Catnip: The Mysterious Herb

Have you ever given your cat catnip and watched their reactions? Some cats roll around, others rub against surfaces, and others become vocal.

The active ingredient in this mysterious herb that elicits these reactions is nepetalactone. Catnip, also known as catmint, is a herb that belongs to the mint family.

This herb has been used for centuries for various purposes, from treating coughs in humans to repelling pests. In this article, we will explore the fascinating world of catnip and examine its effects on our furry friends.

Catnip Response in Cats

Cats are the only animals that display a response to catnip. This herb has an autosomal dominant trait meaning it’s inherited from one or both parents.

About 50% of cats are affected by this trait, while the rest are unaffected. This response to catnip is linked to the sensory neurons in the olfactory system that are responsible for detecting certain scents like nepetalactone.

When cats come in contact with catnip, they respond with various behaviors such as rubbing against the surface, sniffing, licking, chewing, rolling over, and vocalizations. Interestingly, cats under three months of age are not affected by catnip as they haven’t yet developed the olfactory neurons that are linked to nepetalactone.

Varying Reactions to Catnip

While most cats react positively to catnip, others don’t seem affected by it at all. There are also a few cats that develop an adverse reaction to catnip.

Factors such as the cat’s age, sex, and breed can influence their reaction to this herb. Male cats tend to have a more intense response to catnip than females, while kittens may not respond until they’re around six months old.

Some cats are also more susceptible to catnip than others, depending on their genetic makeup. For instance, Siamese cats and other Oriental breeds tend to have a stronger response to catnip than other breeds.

Dog owners may also be surprised to know that their furry friends can be affected by catnip the same way cats are.

Nepetalactone and Nepetalic Acid

The active ingredient in catnip is nepetalactone, which is an organic compound. This compound is produced by the plant as a metabolic byproduct, and cats are attracted to it.

When cats come in contact with nepetalactone, it triggers a behavioral response. Another compound found in catnip is nepetalic acid, which is believed to be a byproduct of the plant’s photosynthesis.

Unlike nepetalactone, this compound doesn’t elicit a response in cats. However, it plays a role in repelling pests.

Repelling Pests with Catnip

Catnip has long been used in pest control due to its ability to repel insects like mosquitos. The active compound in catnip, nepetalactone, has been found to be 10 times more effective than DEET (a chemical found in most insect repellents).

It’s also a natural alternative to synthetic pesticides, making it a safer and environmentally friendly option. In addition to repelling mosquitos, catnip is also effective against other pests like cockroaches, termites, ticks, and flies.

This natural repellent can be used in gardens, homes, and even in personal bug sprays.


Catnip is a fascinating herb that has been used for centuries for various purposes. Its ability to elicit a response in cats has made it popular among pet owners.

Understanding the science behind catnip and how it affects our feline friends is essential in ensuring their well-being. Take some time to experiment with catnip and observe how your cat reacts to it.

You might be surprised at how entertaining it can be!

Catnip and Kittens

Kittens are adorable, playful, and curious little creatures that can take over our hearts in an instant. As they grow and develop, they become more and more curious about their surroundings, including the world of catnip.

However, it’s essential to know the age limit for cats and the response to catnip in kittens before introducing it to them.

Catnip Response in Kittens

Kittens are not affected by catnip until they reach the age of three to six months, where their olfactory neurons begin to develop and become sensitive to nepetalactone. This response to catnip develops over time and is not present in all kittens.

In most cases, kittens develop an attraction to catnip as they age, but there are some exceptions where they may not respond to it at all. As cute and cuddly as kittens can be, it’s important to know that moderation is key when it comes to introducing them to catnip.

Overindulging in catnip can lead to various behaviors such as hyperactivity, irritability, and even aggressive behavior. Thus, it’s essential to observe how your kitten responds to it before giving them free access to the herb.

Growing Catnip for Sustainability

Catnip is a relatively easy herb to grow, and with a little effort, you can grow it in an indoor container garden, providing a fresh supply for your feline friend. Growing catnip indoors is a sustainable and convenient way to ensure you always have fresh catnip without having to go to the store to get it.

Catnip is easy to care for and can thrive in various growing conditions. It requires plenty of sunlight, well-draining soil, and regular watering.

You can start growing catnip from seeds or cuttings, and with proper care, your plant can last several years.

Safety of Catnip

Catnip can provide environmental stimulation for cats, which can be both entertaining and beneficial for their well-being. The herb has been known to relax cats, reduce stress, and increase physical and mental activity.

However, as with any herb, there are also potential risks to be aware of.

Positive Effects of Catnip

One of the most well-known effects of catnip is its ability to stimulate cats. Catnip can be a great environmental enrichment tool that promotes physical and mental activity.

It can encourage cats to play, explore, and interact, which can improve their overall well-being. In addition to the stimulation it provides, catnip has a relaxing effect on some cats.

It can help reduce stress, anxiety, and promote calmness and relaxation in cats that are prone to being easily agitated.

Potential Risks of Catnip

While catnip is generally safe for cats, there are potential risks to be aware of. Catnip can exacerbate coughing and wheezing in cats with feline asthma, and excessive consumption can lead to digestive issues, such as vomiting and diarrhea.

In addition, the herb can be a choking hazard if ingested in large quantities. Thus, it’s important to keep an eye on your cat when giving them access to catnip.


Catnip is a fascinating herb that offers a variety of benefits for cats. By understanding the effects of catnip on kittens, growing it sustainably, and being aware of its potential risks, you can provide your feline friend with a fun and stimulating environment that promotes their overall well-being.

In conclusion, catnip is a fascinating herb that has been used for centuries for various purposes. While most cats respond positively to catnip, it’s essential to know the risks associated with excessive consumption and to monitor your cat’s behavior.

Understanding the response to catnip in kittens and growing it sustainably can provide a fun and stimulating environment for your feline friend. The positive effects of catnip, such as reducing stress and promoting physical and mental activity, make it a popular choice among pet owners.

However, it’s crucial to be aware of its potential risks, such as exacerbating feline asthma and causing digestive issues. Overall, by understanding the science behind catnip and being a responsible pet owner, you can provide your cat with a safe and stimulating environment that promotes their overall well-being.
