At What Age Can Cats Have Catnip?
May 4, 2025
Cats are playful and curious creatures, and catnip is one of the most exciting treats for them. However, pet owners often wonder, what age can cats have catnip?
While catnip is a common delight, it’s important to know when it’s appropriate to introduce it to your cat. Offering catnip too early may not be effective, as kittens under a certain age won’t respond to it.
How Catnip Affects Kittens Under Six Months
For kittens under six months, catnip doesn’t have much effect. Their bodies are still developing. They lack the necessary receptors in their brains to respond to the compound found in catnip. This compound, called nepetalactone, affects adult cats by triggering a euphoric response.
However, kittens do not exhibit this behavior until their sensory systems mature. As a result, kittens younger than three to six months usually show no interest in catnip, even if it’s placed in front of them.
Kittens are more likely to start responding to catnip as they age. Around three months, the receptors in their brains begin to develop. Even then, their reactions may be milder compared to adult cats. This delayed response is simply part of their growth process, and it does not mean they are not able to enjoy catnip later.
Why Kittens Don’t Respond to Catnip Early
Kittens’ inability to respond to catnip early on can be traced back to the development of their neural pathways. The sensitivity to catnip develops as they grow, particularly as their sensory system matures. The compound nepetalactone in catnip interacts with receptors in the brain that are not yet present or fully functional in very young kittens.
As a kitten matures, these receptors begin to work. They can then experience the usual reactions, such as excitement, playfulness, or relaxation.
This lack of response isn’t a problem; it simply reflects the kitten’s stage of development. Just like their other senses, the ability to react to catnip is learned and not innate in the early months of life.
What Age Can Cats Have Catnip?
The best time to introduce catnip to a cat is around six months of age. At this point, most cats have developed the necessary brain receptors to respond to catnip. When you offer it, be sure to use small amounts at first. The goal is to see how your cat reacts without overwhelming them. Some cats may not be interested at all, while others may show signs of excitement or curiosity.
It’s also important to remember that not all cats will respond to catnip. Sensitivity to catnip is hereditary. This means some cats might never react, even after reaching the appropriate age. The first introduction should be done cautiously to gauge your cat’s reaction.
Signs That Your Cat is Ready for Catnip
Knowing when your cat is ready for catnip can be simple. Look for signs of maturity and curiosity in your cat. If your cat is over six months old and exhibits playful behaviors, it may be time to try offering catnip. A cat that shows interest in new toys or smells is more likely to respond positively to catnip. However, if your cat is still indifferent or shows no interest, you can try again in a few weeks or months.
In some cases, a cat may show little interest in catnip even after reaching the proper age. This does not mean there is a problem, but rather that your cat’s genetic makeup may make them immune to the effects of catnip.
Effects of Catnip on Adult Cats Explained
For adult cats, catnip can have a variety of effects. The most common response is a burst of excitement, where the cat may roll, rub, or play vigorously with the herb. Some cats become relaxed, calm, or even sleepy after engaging with catnip. The effects are typically short-lived, lasting anywhere from 10 to 15 minutes. Afterward, most cats lose interest for a while before becoming sensitive to the catnip again.
The effects vary widely from cat to cat. While one cat may become highly energetic, another may simply enjoy a more laid-back feeling. The intensity of the reaction depends on the cat's unique sensitivity and individual preferences.
Can Older Cats Enjoy Catnip Too?
Yes, older cats can enjoy catnip. In fact, senior cats can benefit from the stimulation catnip provides. Just like adult cats, older cats with the right receptors will respond to catnip. While older cats might not react as intensely as younger ones, they can still enjoy the calming effects or the playful energy that catnip can bring.
How Often Should You Give Catnip to Cats?
Catnip should be offered in moderation. While it’s safe for cats, giving it too often may cause them to lose interest. A few times a week is usually enough to keep your cat engaged without overloading their senses.
Some cats may become desensitized if exposed to catnip too frequently. Therefore, keeping it occasional makes sure they continue to enjoy it when they do receive it.
Each cat’s tolerance and interest level can vary. For that reason, adjust the frequency according to your pet's response. Some cats may love catnip so much that they want it daily, while others may be content with a once-in-a-while treat.
Different Ways to Introduce Catnip to Cats
There are several ways to introduce catnip to your cat. You can sprinkle it on their favorite toys, use catnip-infused scratching posts, or even offer it in a bowl for them to sniff and explore. Some pet owners use catnip sprays on their furniture or beds to attract their cats and encourage play.
Best Types of Catnip for Cats to Enjoy
Not all catnip is the same. The type of catnip can affect how much your cat enjoys it. Fresh catnip tends to have the most potent scent and is the most attractive to cats. Dried catnip is also effective but may lose its potency over time. Some catnip is more concentrated or finely ground. This brings a stronger aroma that could attract more attention from your cat.
