What is Catmint and Why Do Cats Love It?
Catmint, scientifically known as species within the genus Nepeta, is a fragrant herb cherished by gardeners for its attractive foliage and long-lasting blooms. However, its most famous attribute, particularly for cat owners, is its profound effect on domestic cats. While often confused with catnip (Nepeta cataria), other varieties of catmint can elicit a similar, albeit sometimes milder, euphoric response in many felines. This fascination stems from a chemical compound called nepetalactone, found in the plant's essential oils. When cats inhale nepetalactone, it stimulates their olfactory receptors, leading to a cascade of behaviours that can include rolling, rubbing, drooling, and general playful excitement.
- Nepetalactone in catmint triggers feline euphoria.
- Cats exhibit varied behaviours like rolling and rubbing.
- Not all cats respond equally to catmint.
- Gardening with catmint can benefit curious pets.
The nepetalactone molecule is thought to mimic feline pheromones, temporarily overriding their usual behaviours with a state of intense pleasure. This reaction is genetically determined; not all cats possess the gene that makes them sensitive to nepetalactone. Kittens under six months and some adult cats may show little to no interest. For those that do respond, the effects are typically short-lived, lasting only about 5 to 15 minutes, after which the cat becomes temporarily immune and may not react again for an hour or more.
The appeal of catmint for cats is more than just a fleeting amusement. It can provide mental stimulation and enrichment, particularly for indoor cats. Introducing them to a safe, plant-based sensory experience can be a wonderful way to engage their natural instincts. As a plant, catmint is also relatively robust and easy to grow, making it a popular choice for gardens frequented by cats, provided it is planted in a location where the plant's well-being is also considered.
Which Cats Respond to Catmint?
The mystery of feline sensitivity to catmint lies largely in genetics. It's estimated that between 50% and 80% of adult cats carry the gene that predisposes them to react to nepetalactone. This means that if your cat doesn't seem interested, it's not a reflection on the plant or your cat's personality, but simply a matter of genetics. Younger kittens often don't show a strong reaction until they are several months old, and some adult cats, despite having the gene, may simply not be very responsive. It's worth noting that while lions, tigers, and other big cats also react to nepetalactone, the intensity and specific behaviours can differ from domestic cats.
For those cats that are sensitive, the reaction is generally predictable. They might sniff the plant, chew on a leaf, and then engage in a 'rolling' behaviour, often arching their backs and rubbing their heads and bodies against the plant or the ground nearby. Some cats may become very playful, batting at imaginary objects or running around, whilst others might become quite relaxed and even appear drowsy after the initial excitement wears off. The intensity of the response can vary, with some cats having a mild curiosity and others exhibiting a full-blown 'high'.
The presence of nepetalactone is the primary driver of a cat's interest. It’s the 'magic ingredient' that unlocks this unique feline behaviour. If you're unsure whether your cat will respond, you could try introducing a small amount of dried catmint or a catnip toy first, as these often contain concentrated oils.
Common Misconceptions: Catnip vs. Catmint
It's important to distinguish between catnip (Nepeta cataria) and other varieties commonly referred to as catmint. All catnips are catmints, but not all catmints are catnip. Catnip is specifically Nepeta cataria and is known for its potent nepetalactone content, often producing the most pronounced reactions in cats. Other popular garden varieties like Nepeta x faassenii (often sold as 'Walker's Low' or 'Six Hills Giant') also contain nepetalactone, but often in lower concentrations. This means they might still attract cats, but the reaction could be less intense or may only affect the most sensitive individuals. If your primary goal is to attract cats, Nepeta cataria is generally the most reliable choice.
Growing Catmint for Your Feline Friends
If you're considering planting catmint to delight your cat, understanding its growing needs will ensure a healthy, fragrant plant. Catmint thrives in full sun to partial shade and prefers well-drained soil. It is remarkably drought-tolerant once established, making it a low-maintenance addition to any garden. Many varieties, such as the widely available 'Walker's Low', form bushy mounds and produce spikes of lavender-blue flowers from late spring through to autumn, providing colour and scent for months. This long flowering period means a continuous source of potential interest for your cat.
Plant catmint in a designated area away from your vegetable patch or prize-winning flowers if you want to limit your cat's interaction and prevent them from trampling other plants. Consider a low border or a dedicated sensory garden section for your feline friend.
When planting, ensure the soil is not too rich or wet, as this can lead to root rot. Good drainage is key. For established plants, a light pruning after the first flush of flowers can encourage a second bloom and keep the plant tidy. This is particularly useful if your cat tends to flatten the plant. The fragrance is most potent when the leaves and stems are bruised or crushed, which is precisely what happens when a cat interacts with it.
Which Catmint Varieties Are Best?
While Nepeta cataria (catnip) is the most potent, other garden varieties offer a slightly different experience. 'Six Hills Giant' is a vigorous grower with a strong scent that often attracts cats. 'Walker's Low' is a popular, compact choice that blooms profusely. For a more contained plant, 'Little Trudy' is a dwarf variety. When selecting, look for descriptions that mention attractiveness to cats or high essential oil content. It's also wise to consider the plant's mature size and habit to ensure it fits your garden space and can withstand enthusiastic feline attention.
The fragrance is the key attractant for cats. Ensure you provide plants with good air circulation and adequate sunlight to promote healthy growth and maximum oil production.
When introducing the plant to your cat, it's best to let them discover it naturally. You might initially find your cat is more interested in the soil than the plant itself, or they might simply ignore it. Patience is often rewarded. If your cat shows interest, allow them supervised access. Be aware that some cats can become over-excited and might chew on or dig around the plant. If this becomes an issue, you may need to fence off the area or offer the plant only in moderation.
Beyond the Buzz: Other Benefits of Catmint
Whilst the primary draw for many is the feline fascination, catmint offers substantial benefits to gardeners and the wider ecosystem. Its hardy nature and long flowering season make it a superb plant for adding colour and texture to borders and containers. The lavender-blue flowers are a magnet for pollinators, including bees, butterflies, and hoverflies, contributing positively to garden biodiversity. This makes it a valuable plant for wildlife gardens, not just for attracting cats.
From a horticultural perspective, catmint is incredibly versatile. It can be used as a ground cover, an edging plant, or grown in drifts for a more naturalistic effect. Its aromatic foliage also has the advantage of being largely deer and rabbit resistant, a welcome trait for gardeners battling common pests. The plant's ability to tolerate poor soil and dry conditions means it's an excellent choice for difficult spots or for low-water gardening schemes. Pruning after flowering encourages reblooming and maintains a tidy appearance.
The resilience of catmint makes it a gardener's friend. It’s a plant that gives back, offering beauty, attracting beneficial insects, and providing a unique sensory experience for our feline companions. Its evergreen or semi-evergreen foliage can also provide some winter interest in milder climates, though it typically benefits from a cut back in early spring to encourage fresh growth.
Catmint in the Garden Design
Integrating catmint into your garden design is straightforward. It pairs well with other drought-tolerant perennials and ornamental grasses, creating a harmonious, naturalistic look. Consider planting it alongside plants that appreciate similar conditions, like salvias, sedums, or achilleas. The soft grey-green foliage of catmint can provide a lovely contrast to plants with darker or more vibrant leaves. If you're planting smaller varieties, they can tuck nicely into rockeries or be used to spill over the edges of raised beds.
For those interested in companion planting, the aromatic nature of catmint might offer some pest-repelling qualities, though this is often anecdotal. However, its primary companion role is certainly with cats. Providing them with safe access to a plant they naturally adore can enhance their quality of life, offering a natural outlet for their instincts and curiosity, much like providing them with a stimulating toy or a scratching post.
