What Plants Do Cats Hate? Cats vs. Plants

The Ultimate Guide to Cat-Repellent Plants

Why Do Cats Dislike Certain Plants?

Cats, known for their curious and playful nature, often exhibit a strong dislike for specific plants. While some foliage may seem inviting to us, it can trigger a completely different reaction in our feline friends. Understanding why cats detest certain plants can provide insight into creating a safe and cat-friendly environment.

Sensitive Smell

Cats have a highly developed sense of smell. What might seem like a pleasant fragrance to us could be overwhelmingly strong or off-putting to them. Plants such as lavender, rue, or Coleus Canina emit scents that humans might find appealing but are repulsive to cats due to their sensitivity to certain aromatic compounds.

Defensive Mechanisms

Plants have developed various defense mechanisms to deter animals from eating them. Some of these deterrents are chemicals or compounds that create an unpleasant taste or smell. For example, citrus plants contain oils in their peels that cats find offensive. These natural defenses evolved in plants to protect them from being consumed by herbivores, and cats, in turn, avoid these plants due to their unappealing properties.

Genetic Predispositions

Cats may have genetic predispositions that make them naturally averse to certain scents or tastes. This aversion can be an instinctive response passed down through generations. For instance, the Scaredy Cat Plant (Coleus Canina) emits an odor that's similar to a skunk's scent, triggering a response in cats to avoid it.

Toxicity Awareness

Cats possess an innate ability to recognize and avoid toxic substances. Some plants that repel cats, such as rue, also happen to be toxic if ingested. Cats might inherently sense the potential danger and avoid these plants, showcasing an instinctive avoidance of potentially harmful substances.

Individual Preferences

Similar to humans, cats have individual preferences and aversions. What repels one cat might not bother another. Their unique personalities, past experiences, and sensitivities contribute to their likes and dislikes when it comes to plants.

Understanding why cats dislike certain plants can aid in creating a safe and enjoyable environment for both your pet and your garden. While these plants might deter cats, it’s crucial to remember that each cat is different, and supervision in the garden remains essential to prevent accidental ingestion of any potentially harmful foliage.


Crafting a Cat-Safe Oasis: Plants that Cats Hate

For cat owners who adore gardening but worry about their furry companions, creating a cat-friendly garden is a delightful challenge. Cats' inquisitive nature often leads them to explore green spaces, but certain plants can pose health hazards. Fortunately, there are various cat-repellent plants you can cultivate to keep your garden lush and your feline friend safe.

Coleus Canina (Scaredy Cat Plant)

Known for its ability to repel cats, Coleus Canina, or the Scaredy Cat Plant, emits an odor that felines find off-putting. This plant, resembling traditional coleus with a unique fragrance reminiscent of skunks, effectively deters cats while being harmless to humans.


Loved by humans for its soothing scent, lavender acts as a natural cat repellent due to its strong aroma, which cats detest. Planting lavender not only adds beauty and fragrance to your garden but also helps keep cats away.


Rue, characterized by its attractive blue-green foliage and delicate yellow flowers, emits a scent that cats find repulsive. However, caution is advised with Rue, as it can be toxic to both cats and humans if ingested. It’s best planted in areas inaccessible to pets.

Citrus Plants

Citrus plants like oranges and lemons contain oils in their peels that are offensive to cats. Incorporating these citrus trees or plants into your garden landscape can effectively discourage cats from exploring certain areas.

Plectranthus (Coleus) Caninus

Also known as the "Dogbane" plant, Plectranthus Caninus is closely related to the Scaredy Cat Plant and shares similar cat-repelling properties. Its strong smell is unappealing to cats, making it an excellent addition to your garden.

Crafting a cat-friendly garden involves more than just planting these cat-deterring species.

Consider these tips:

Ensure Safety: While these plants discourage cats, some felines may remain curious. Supervising your pet outdoors is essential to prevent them from ingesting potentially harmful plants.

Research Toxicity: While Rue has cat-repelling qualities, it can also be toxic. Always research the toxicity of plants and place them strategically to avoid accidental ingestion by your cat.

Create Cat Zones: Designate certain areas of your garden specifically for your cat. Incorporate safe plants like catnip, wheatgrass, or oat grass, creating a space where your pet can play and relax.

By strategically planting cat-deterring species and considering your cat's safety, you can create a beautiful, safe haven for both your garden and your beloved pet.

Remember, while these plants help deter cats, it's crucial to remain vigilant about your cat's activities in the garden.
