Cats are always curious about everything around them. They find unique and creative ways of entertaining themselves, like climbing onto shelves or leaping and trying to fit themselves into cardboard boxes.

As pet owners, we often find ways to bring excitement into the mix. From interactive cat toys and treats to cooperative games, each serves as a mood booster for our best friends. 

But perhaps one of their favorite things in the world is catnip. It’s a mysterious herb that can make cats do funny and fascinating things. Catnip comes in dry and fresh variants, and some toys even have this herb in them. 

Before you go buying the first product you see online, we’re here to tell you all about what catnip is. We’ll discover why it affects cats, its safety, and the best ways to use it.

What Is Catnip?

Catnip is an herb that's member of the mint family, which has varying effects on cats

Nepeta cataria is the scientific name of catnip. It’s a flowering plant that’s a member of the mint family. Catmint, catnep, and catwort are just some of its other names.

This herb from the mint family has square stems, soft green leaves, and clusters of pale purple or white flowers. It can grow in well-drained soil in full sun. It’s local in the regions of Africa, Europe, and Asia, but it’s also grown in some parts of North America.

The important chemical compound in catnip is called nepetalactone, which triggers different reactions in cats. This chemical compound is found in the stem, leaves, and seeds of the plant. However, not all cats react the same way. 

According to a study published in BMC Veterinary Research, around two out of three cats react to catnip. This means that there’s a chance that your cat won’t be affected or show any interest in this herb.

It’s also important to remember that kittens three months old and younger don’t usually show any reactions to catnip. It’s mainly because their sensory systems are still too young to respond to nepetalactone. Senior cats, on the other hand, can also lose their interest over time due to old age.

What Does Catnip Do to Cats​?

So, what happens when you give your cat some catnip? The effects vary depending on how it’s used. First, it starts with the nose. 

When your cat sniffs the herb, the nepetalactone affects their nasal tissue receptors. They send signals to the cat’s brain to the parts that control their behavior and emotions, which are the hypothalamus and amygdala. 

This process makes cats roll and flip around, rub their heads, vocalize a lot, and play with so much energy. 

Now, when it is eaten, it can have a calming effect. This could be the reason why your cat can be acting hyper one minute, then suddenly stop, stare blankly, and just appear to be extremely relaxed. 

How Long Do the Effects of Catnip Last?

The effects of catnip on cats can last for about 10 to 15 minutes. After that, your cat will become temporarily immune to the herb. It may take a few hours before the immunity wears off, so give the herb sparingly. 

What Are the Benefits of Catnip for Cats?

While it’s true that many pet parents enjoy and get excited to see how their cats may react to catnip, many might not know that it also has health benefits. Here are some ways catnip supports a cat’s mental and physical health.

Mental Stimulation

Catnip keeps your pet’s environment interesting. Because of their love of exploring textures and scents, this can help them be mentally stimulated. It’s significantly useful for indoor cats, especially since they don’t get to experience natural stimuli outside. 

Stress Relief

Catnip also has a calming effect on cats, making it useful when they are stressed or anxious. It’s also sometimes used for promoting good sleep and naps. Catnip is very useful if you’re visiting places that are new and scary for your cat, such as vet visits and grooming salons. 

Encourages Exercise

The herb also serves as a way to promote exercise and play. It works by stimulating the cat’s senses and behavior, encouraging them to get up and play. The spontaneous burst of activity works great in helping cats maintain a healthy weight and overall fitness. 

Training Tool

Catnip works great in introducing cats to new objects and toys. If you want to give your cat new stuff, simply apply the catnip to it, and it’ll have an easier time. This also helps tremendously in redirecting destructive behavior, such as scratching furniture.

Bonding and Socialization

Sharing playtime with catnip toys creates enjoyable bonding moments between you and your cat. It makes the cat’s life much more interesting and fun, especially with you right by their side. 

Is Catnip Actually Safe for Cats?

While catnip is beneficial for cats, there are some instances when it’s not. This can often come from giving too much catnip or giving all the time. 

  • Overstimulation. Too much catnip can make some cats restless, hyperactive, and even aggressive. This can manifest in signs such as biting and swatting. Because of this, it’s important to monitor your cat and only give small amounts. 

  • Digestive Upset. When eaten in large amounts, cats can experience digestive upset. This can result in vomiting or diarrhea. While it’s not that dangerous, it can be very uncomfortable for your cat. Limiting helps avoid tummy troubles. 

Vet Tips: How to Use Catnip Effectively

A vet is slowly petting a white cat and making it comfortable.

There are many ways to give catnip to your cat. It may depend on your pet’s preference and how you plan to use it. Also, it’s always good to consult with our pet behaviorists to check your cat’s behavior and the best ways to use catnip.

Here are some ideas on how to use it effectively in your cat’s routine based on the type.

  1. Dry Catnip

Dry catnip is one of the most popular forms of this herb. You can sprinkle it on their bedding, toys, or scratching posts. It’s highly potent and affordable compared to other types. Also, it’s easy to purchase. Several pet stores offer several varieties and options.  

Store it in the freezer or in an airtight jar to keep it aromatic and fresh.

  1. Fresh Catnip

If you prefer to grow these plants at home or have a source for fresh catnip, your cat can enjoy chewing on the leaves. It not only provides additional entertainment for them, but its potency is at its highest. 

However, make sure to monitor your cat for any signs of stomach upset. Catnip can be too strong for cats that are sensitive. 

  1. Catnip Spray

If cleaning up pieces of dried herb and catnip leaves is something that you won’t be able to do, opt for the spray variants. These are convenient and clean, as you’ll only need to spritz them on toys, furniture, and other items.

You can use the spray to stimulate your cat’s response to an object. If you want to let your cat use a new toy or scratching post, just apply a few sprays.

  1. Catnip Toys

There are many catnip toys for cats available in pet supply stores. These include crinkly balls, small plushies, and various forms of toys infused with catnip. 

How Much Catnip Should You Give?

The correct amounts of catnip will vary depending on the cat and the form of catnip you choose to give. You can give small amounts at first. Try out a pinch of dried herb, a small piece of fresh leaf, or a spritz of the spray. 

Don’t do this daily, but try giving once or twice a week. When giving, observe your cat’s behavior and adjust the amount when you give catnip again. You should also notice if your cat wants more or less. 

"Catnip is one of the many ways we can make our cats smile."

Final Thoughts on Catnip

Fresh leaves, a stuffed toy, or sprayed on a scratching post, catnip can add color and fun to your cat’s life. It can calm them when they are stressed or boost their energy when they’re feeling a little down.

Just remember to use catnip wisely. Always monitor your cat’s reaction to the herb, and use it in moderation. Give the right amounts and you’ll keep your cat’s experience exciting and fresh.
