Cats using gardens as their personal litter boxes is a common frustration for many homeowners. The lingering odours, unsightly messes and potential health risks make finding an effective deterrent a priority.
Among the various solutions, some plants emit scents that cats find unappealing, encouraging them to steer clear of treated areas. One such plant is the Scaredy Cat Plant (Coleus canina), which has gained attention for its strong, skunk-like smell that is said to repel cats, dogs and other wildlife.
This semi-succulent perennial produces small, attractive blue flowers and thrives in sunny locations with well-drained soil. It’s also known for being low-maintenance and drought-tolerant, making it a practical choice for gardeners looking to protect their outdoor spaces. However, its effectiveness as a cat deterrent is debated.
, the plant emits a scent that is generally unpleasant to cats, leading them to avoid its vicinity.
However, the publication also notes that Coleus canina is not hardy and may require indoor protection during colder months. This means its effectiveness may be seasonal, limiting its use for year-round cat prevention.

While the Scaredy Cat Plant can be part of the solution, other plants also work as natural deterrents due to their strong scents:
- Lavender: While pleasant to humans, lavender’s aroma is often overwhelming for cats, making it an effective repellent.
- Rosemary: This aromatic herb has a scent that many cats dislike. It’s also an evergreen plant, providing protection all year round.
- Rue: Traditionally used as a natural insect repellent, rue’s strong smell is also known to deter cats. However, it should be handled with care as it can cause skin irritation.
- Pennyroyal: A member of the mint family, pennyroyal emits a powerful scent that cats tend to avoid.
- Curry Plant: This herb, with its distinct curry-like aroma, is often considered effective in discouraging cats from entering garden spaces.

To maximize the effectiveness of these natural deterrents, consider the placement of the plants, which should be around the perimeter of your garden, near entry points, or in areas where cats frequently dig or relieve themselves. Plan for dense planting, and try having a thick arrangement of plants to create a stonger barrier.
