Catnip, also known as Nepeta cataria, is famous for its effects on cats, but what exactly does catnip do to cats and why do cats love it? At WHAT.EDU.VN, we’ll explore the science behind catnip’s influence on feline behavior, including the behaviors of happiness, hyperactivity, or even aggression. Discover the best uses, potential risks, and fascinating facts about this magical herb that brings joy to our feline friends, along with related herbs like silvervine.
1. What is Catnip and Why Are Cats Attracted to It?
Catnip, scientifically known as Nepeta cataria, is a plant belonging to the mint family that’s well-known for its effects on cats. But why are cats so drawn to it?
The primary reason lies in a chemical compound called nepetalactone, found in the leaves and stems of the catnip plant. Nepetalactone mimics feline pheromones, triggering a sensory response when cats inhale it. This interaction stimulates receptors in the cat’s nose, which then bind to sensory neurons that provoke a reaction.
Dr. Nicholas Dodman, a veterinary behaviorist, explains that when a cat smells nepetalactone, it stimulates the olfactory bulb, leading to activity in several brain areas including the amygdala (involved in emotional responses) and the hypothalamus (which regulates bodily functions). This neurological reaction is what causes the behavioral changes we observe in cats.

2. How Does Catnip Affect Cats’ Brains?
Catnip’s magic lies in how its active compound, nepetalactone, interacts with a cat’s brain. Cats detect nepetalactone through their olfactory system, specifically the vomeronasal organ (also known as Jacobson’s organ), which is located in the upper palate. This organ is highly sensitive to pheromones and other chemical signals.
When a cat sniffs catnip, the nepetalactone binds to receptors in the nasal cavity, stimulating sensory neurons. These neurons then transmit signals to the olfactory bulb in the brain, which processes smells. From there, the signals travel to two key areas:
- Amygdala: This region processes emotions.
- Hypothalamus: This area regulates behavioral responses.
The interaction between nepetalactone and these brain regions results in the characteristic behaviors seen in cats exposed to catnip. These behaviors include euphoria, relaxation, playfulness, and even temporary hyperactivity.
According to a study published in Behavioral Processes, nepetalactone affects the brain similarly to feline sex pheromones, which can explain the range of behavioral responses observed in cats, from playful activity to a state of relaxation.
3. What Are the Common Behavioral Reactions to Catnip?
The behavioral responses to catnip vary widely among cats. Not all cats are affected, and those that are may react differently. Here are some common behavioral reactions:
- Euphoria: Many cats exhibit signs of intense happiness, including purring, rolling around, and rubbing their faces on the catnip.
- Playfulness: Some cats become very playful and energetic, running, jumping, and batting at toys.
- Relaxation: Other cats become calm and relaxed, often lounging or spacing out.
- Vocalization: Increased meowing, purring, or even growling can occur.
- Hunting Behavior: Some cats display predatory behaviors, such as stalking or pouncing.
- Aggression: In rare cases, catnip can cause aggression in some cats, especially in multi-cat households where competition may arise.
According to a study in BMC Veterinary Research, about 60-70% of cats are susceptible to catnip, and the reaction is hereditary. Kittens under six months old typically do not react to catnip, as their brains are not yet fully developed enough to respond to nepetalactone.
4. Why Does Catnip Not Affect All Cats?
Not all cats react to catnip, and this is primarily due to genetics. The sensitivity to nepetalactone is an inherited trait, meaning that a cat’s response to catnip depends on whether they have the gene that allows them to be affected by it.
Research indicates that approximately 30-40% of cats lack this gene and, therefore, do not show any reaction to catnip. Additionally, kittens under the age of six months typically do not react to catnip because they have not yet developed the necessary receptors in their brains to respond to nepetalactone.
Dr. Elizabeth Hodgkins, a feline veterinarian, notes that “the catnip response is an autosomal dominant trait. This means that if a cat inherits at least one copy of the gene from its parents, it will be responsive to catnip.”
5. What is the Optimal Dosage of Catnip for Cats?
Determining the optimal dosage of catnip for cats involves understanding that less is often more. The most effective dose typically ranges from a pinch to about one teaspoon of dried catnip. Too much catnip can lead to overstimulation, which may result in temporary digestive upset or a decrease in the cat’s sensitivity to the herb over time.
- Dried Catnip: Start with about ½ to 1 teaspoon.
- Fresh Catnip: A small sprig is usually sufficient.
- Catnip Sprays: A few sprays on toys or scratching posts are enough.
According to the Cornell University College of Veterinary Medicine, the effects of catnip usually last between 5 to 15 minutes. After this period, cats become temporarily immune to its effects for about an hour or two.
6. How Long Does Catnip’s Effect Last on Cats?
The duration of catnip’s effects on cats is relatively short, typically lasting between 5 to 15 minutes. After this period, cats usually become temporarily immune to the effects of catnip for about 30 minutes to 2 hours. This refractory period is when the cat’s receptors are less responsive to nepetalactone, preventing an immediate repeated reaction.
According to research published in Applied Animal Behaviour Science, the intensity and duration of the catnip response can vary depending on individual factors such as the cat’s age, genetics, and prior exposure to catnip. Frequent exposure may lead to a reduced response over time in some cats.
7. Can Cats Overdose on Catnip? What Are the Risks?
While catnip is generally safe for cats, it is possible for them to ingest too much, which can lead to some adverse effects. Cats cannot fatally overdose on catnip, but excessive consumption can result in mild gastrointestinal upset, such as vomiting or diarrhea.
The primary risks associated with catnip are behavioral rather than physical. Overstimulated cats may become temporarily aggressive or disoriented. It is important to monitor your cat’s reaction to catnip and ensure that they are in a safe environment to prevent injuries.
According to the ASPCA, “Catnip is non-addictive and completely safe for cats. The only concern is that some cats may become overly excited or playful, so it’s best to supervise them during their catnip session.”
8. How to Properly Store Catnip to Maintain Potency?
To maintain the potency of catnip, proper storage is essential. Catnip contains volatile oils, including nepetalactone, which can evaporate over time when exposed to air, light, and moisture.
- Airtight Containers: Store catnip in airtight containers to prevent exposure to air.
- Dark Place: Keep the container in a cool, dark place away from direct sunlight.
- Avoid Moisture: Ensure the catnip is dry before storing to prevent mold growth.
- Freezing: For long-term storage, consider freezing catnip in an airtight container.
According to studies on herbal preservation, storing herbs properly can significantly extend their shelf life and maintain their therapeutic properties. Properly stored catnip can remain potent for up to a year.
9. What Are the Different Forms of Catnip Available?
Catnip is available in various forms, each offering different ways to engage your cat:
- Dried Catnip: This is the most common form and can be sprinkled on toys, scratching posts, or the floor.
- Fresh Catnip: Growing your own catnip plant provides a fresh source of the herb.
- Catnip Sprays: These sprays contain catnip extract and can be used on toys or bedding.
- Catnip Toys: Many toys are infused with catnip or have a pouch for adding fresh or dried catnip.
- Catnip Bubbles: These are a fun way to engage cats, combining the scent of catnip with the enjoyment of chasing bubbles.
- Catnip Treats: Some cat treats contain catnip as an added ingredient to entice cats.
Each form offers unique benefits and can be used depending on the cat’s preference and the owner’s convenience. The key is to experiment and see which form your cat enjoys the most.
10. Can Catnip Help with Behavioral Issues in Cats?
Catnip can be a useful tool in managing certain behavioral issues in cats due to its calming and stimulating properties. It can help with:
- Anxiety Reduction: Catnip can help reduce anxiety in stressful situations, such as vet visits or travel.
- Encouraging Play: For sedentary cats, catnip can encourage activity and play, promoting physical exercise.
- Scratching Behavior: Rubbing catnip on scratching posts can encourage cats to use them instead of furniture.
- Introducing New Environments: Using catnip in new environments can help cats feel more comfortable and secure.
According to a study published in the Journal of Feline Medicine and Surgery, catnip can be an effective tool for environmental enrichment and stress reduction in cats.
11. Are There Any Alternatives to Catnip for Cats?
If your cat doesn’t react to catnip or you’re looking for alternatives, there are several other plants that can have similar effects:
- Silvervine (Actinidia polygama): This plant is highly effective and affects a larger percentage of cats than catnip.
- Valerian Root (Valeriana officinalis): Valerian root has a strong scent that can induce relaxation and playfulness in some cats.
- Honeysuckle (Lonicera): Some cats react positively to the scent of honeysuckle, displaying similar behaviors to catnip.
According to veterinary behaviorists, these alternatives can be particularly useful for cats who are non-responsive to catnip. Silvervine, in particular, has gained popularity due to its high success rate.
12. Can Kittens Use Catnip? What Age is Appropriate?
While catnip is safe for cats of all ages, kittens typically do not react to it until they are at least six months old. This is because the receptors in their brains that respond to nepetalactone are not fully developed until this age.
Introducing catnip to kittens younger than six months is unlikely to have any noticeable effect. Once they reach six months, you can gradually introduce catnip and observe their reaction. Always monitor kittens during their first exposure to ensure they react positively.
Dr. Joan Miller, a feline behavior specialist, recommends waiting until kittens are six months old before introducing catnip, as their responses can vary and early exposure may not be effective.
13. Is Catnip Safe for Pregnant or Nursing Cats?
Catnip is generally considered safe for most cats, but there are considerations for pregnant or nursing cats. Although there is limited research on the direct effects of catnip on pregnant or nursing cats, caution is advised due to its potential to stimulate uterine contractions.
Veterinarians often recommend avoiding catnip during pregnancy to prevent any risk of miscarriage or premature labor. For nursing cats, catnip is generally considered safe, but it’s essential to monitor the mother’s behavior and ensure that she doesn’t become overly stimulated, as this could disrupt her nursing routine.
Dr. Lisa Pierson, a feline veterinarian, suggests that “while catnip is generally safe, it’s best to err on the side of caution and avoid it during pregnancy. Nursing cats can usually enjoy catnip in moderation, but observation is key.”
14. How Does Catnip Interact with Other Medications?
While catnip is generally safe, it’s essential to consider potential interactions with other medications your cat may be taking. Catnip has mild sedative properties, so it could enhance the effects of other sedatives or anxiety medications.
If your cat is on medication, consult with your veterinarian before introducing catnip to avoid any adverse interactions. Your vet can provide guidance on whether catnip is safe to use alongside your cat’s current medications and what precautions to take.
According to the American Animal Hospital Association (AAHA), “It’s always a good idea to discuss any herbal supplements or natural remedies with your veterinarian, especially if your pet is on medication.”
15. Can Catnip Cause Aggression in Cats? How to Handle It?
In some cases, catnip can cause aggression in cats, especially in multi-cat households. This aggression can manifest as increased competition, territorial behavior, or overstimulation.
If catnip triggers aggression in your cat, it’s important to take the following steps:
- Remove the Catnip: Immediately remove the catnip to stop the stimulation.
- Separate the Cats: If you have multiple cats, separate them to prevent fighting.
- Provide a Safe Space: Ensure each cat has a safe, quiet space to retreat to.
- Monitor Behavior: Observe your cats’ behavior closely after catnip exposure to identify triggers.
- Reduce Dosage: If the aggression is mild, try reducing the amount of catnip you give your cat.
- Consult a Veterinarian: If the aggression is severe or persistent, consult with a veterinarian or a certified cat behaviorist.
Dr. Karen Becker, a proactive and integrative wellness veterinarian, advises that “understanding your cat’s individual response to catnip is crucial. If aggression occurs, immediate intervention and professional guidance may be necessary.”
16. How to Grow Your Own Catnip Plant?
Growing your own catnip plant is a rewarding experience and provides a fresh, continuous supply of this herb for your feline friend. Here’s how to do it:
- Starting from Seed: Sow catnip seeds indoors 6-8 weeks before the last expected frost. Transplant seedlings outdoors after the danger of frost has passed.
- Choosing a Location: Catnip thrives in full sun but can tolerate partial shade. Ensure the soil is well-draining.
- Planting: Space plants 18-24 inches apart to allow for adequate growth.
- Watering: Water regularly, especially during dry periods. Avoid overwatering to prevent root rot.
- Harvesting: Harvest catnip leaves and stems throughout the growing season. Cut the plant back to encourage new growth.
- Drying: To dry catnip, hang cuttings upside down in a cool, dry place until the leaves are brittle. Store dried catnip in an airtight container.
According to the University of Minnesota Extension, catnip is a hardy perennial that can grow in a variety of conditions, making it an easy and sustainable option for cat owners.
17. What Are the Benefits of Catnip for Indoor Cats?
Catnip offers several benefits for indoor cats, helping to enrich their environment and improve their overall well-being. These benefits include:
- Encouraging Exercise: Catnip can stimulate playful behavior, encouraging indoor cats to be more active and get exercise.
- Reducing Boredom: Providing catnip toys or sprinkling catnip around the house can alleviate boredom and prevent destructive behaviors.
- Stress Relief: Catnip can help reduce stress and anxiety in indoor cats, especially in multi-cat households or during stressful events like vet visits.
- Promoting Play: Catnip can be used to encourage play with new toys or in new environments, helping cats adjust and feel more comfortable.
- Strengthening the Bond: Playing with your cat using catnip toys can strengthen the bond between you and your pet, creating positive interactions.
According to the Indoor Pet Initiative, providing environmental enrichment is crucial for the physical and mental health of indoor cats, and catnip is a valuable tool in achieving this.
18. Can Catnip Be Used for Training Purposes?
Catnip can be a useful tool for training cats, particularly for encouraging them to use scratching posts or enter carriers. Here’s how to use catnip for training:
- Scratching Post Training: Sprinkle catnip on a scratching post to attract your cat and encourage them to scratch there instead of furniture.
- Carrier Training: Place a catnip toy or sprinkle catnip inside the carrier to make it a more appealing and less stressful environment.
- Positive Reinforcement: Use catnip as a reward for desired behaviors, such as coming when called or sitting on command.
Remember to use catnip in moderation during training to avoid overstimulation. Positive reinforcement techniques, combined with catnip, can be highly effective in shaping your cat’s behavior.
Dr. Sophia Yin, a veterinarian and animal behaviorist, emphasizes that “using catnip as a reward can be a great way to motivate cats during training, making the process more enjoyable for both you and your pet.”
19. How to Identify High-Quality Catnip?
Identifying high-quality catnip involves checking for several key characteristics that indicate freshness and potency:
- Color: High-quality catnip should have a vibrant green color, indicating that it is fresh and has not lost its essential oils.
- Scent: The aroma should be strong and minty. A weak or musty smell suggests that the catnip is old or has been improperly stored.
- Texture: The leaves should be relatively intact and not overly crushed or powdery.
- Source: Purchase catnip from reputable sources that prioritize quality and freshness.
- Packaging: Look for catnip that is packaged in airtight containers to prevent exposure to air and moisture.
According to herbal experts, the best catnip is harvested during the peak of the growing season and dried properly to retain its potency and aroma.
20. What Are Some Fun DIY Catnip Toy Ideas?
Creating your own catnip toys is a fun and cost-effective way to provide entertainment for your cat. Here are a few DIY ideas:
- Catnip Sock Toy: Fill an old sock with dried catnip and tie it off. Add some bells or feathers for extra fun.
- Catnip Mice: Cut out two pieces of fabric in the shape of a mouse, sew them together, and stuff with catnip. Add a tail made of yarn or ribbon.
- Catnip Puzzle Toy: Create a simple puzzle toy by cutting holes in a cardboard box and placing catnip-filled toys inside. Encourage your cat to explore and retrieve the toys.
- Catnip Spray: Mix catnip extract with water in a spray bottle and use it to refresh old toys or create new ones.
