While humans are often visually oriented, cats experience their surroundings largely through their sense of smell. Their nose is about 14 times more sensitive than ours, helping them detect food, other animals, and even moods. But many scents we find pleasant can be problematic or even dangerous for cats.

Which scents cats should avoid

Many people love scented candles or room sprays with essential oils, but some of these substances are highly toxic to cats. In particular, tea tree, eucalyptus, and citrus oils can cause poisoning, since cats lack certain enzymes needed to break them down. Studies show that even small amounts can lead to symptoms such as drooling, trembling, or difficulty breathing.

It's not just essential oils — heavily perfumed detergents, air fresheners, or floor cleaners can also affect cats. A study published in the Journal of Feline Medicine and Surgery found that cats in households with intense artificial fragrances more often suffer from respiratory issues.

Which scents cats love

While many artificial fragrances are problematic, there are also scents proven to attract and calm cats. These include:

  • Valerian: Has an effect similar to catnip and can help reduce stress.
  • Olive wood: Many cats love to rub against it, as it gives off gentle scents.
  • Lavender (in very small amounts!): Can have a calming effect, but should only be used in natural form without additives.
