Is Lavender Safe for Cats? The Purrfect Answer on Aromatherapy for Felines


Lavender is a popular herb known for its pleasant floral scent and calming properties. Some of the active compounds found in lavender oil, including linalool and linalyl acetate, have been shown in studies to have anxiolytic (anxiety reducing) and sedative effects when inhaled.[1] Because of this, lavender is commonly used in human aromatherapy to combat stress, anxiety, and promote relaxation and restful sleep.

Like humans, many pets also experience stress and anxiety. Cats in particular are very sensitive to smells in their environment. Some cat owners have started exploring using lavender, through diffusers or calming collars, to help soothe anxious or stressed cats. But is it safe to diffuse lavender around cats? Are there any risks to be aware of?

In this article, we’ll explore the potential benefits and risks of using diffused lavender for cats. We’ll look at appropriate dosages, vet recommendations, what oils to avoid, and owner experiences. By the end, you’ll have the information to decide if diffusing lavender is right for your feline friend.


Potential Benefits

Some potential benefits of diffusing lavender around cats in moderation include:

Reducing stress and anxiety – Lavender has a calming effect and its scent may help relax anxious or stressed cats. Some studies show lavender can reduce signs of anxiety in animals.1

Promoting restful sleep – The sedative properties of lavender may help cats sleep more soundly. The calming scent can potentially aid insomnia and restlessness.

Relieving motion sickness – Diffusing lavender in the carrier or car may help alleviate motion sickness, nausea, and vomiting in traveling cats.

Repelling insects – Lavender has insect repellent properties. The scent may help deter fleas, ticks, and other insects that bother cats.

Improving mood – Inhaling lavender has been shown to lift mood and reduce signs of depression in humans. There’s some evidence it may have similar effects in cats.

Pain relief – Early research shows lavender essential oil may have mild pain-relieving properties when applied topically. It may provide cats some natural pain relief.

The relaxing and sedative effects of lavender are most notable. When used properly, the scent may have a calming effect and help with common feline anxiety issues.

Potential Risks

While lavender can have benefits, it also carries some risks for cats. The main concern is cats ingesting lavender, either by eating the plant or essential oil. According to The Spruce Pets, ingesting lavender can lead to gastrointestinal irritation and liver damage in cats. Lavender contains compounds like linalool and linalyl acetate that are toxic to cats.

Lavender essential oil is especially dangerous if ingested, as noted by Dutch. Even small amounts of lavender oil can cause nausea, vomiting, and liver issues. Topical application may lead to skin irritation in some cats as well.

Inhaling diffused lavender is likely safe in moderation, but airborne oils may still cause respiratory irritation for some cats. It’s best to closely monitor your cat’s reaction and watch for any signs of distress when diffusing lavender around them.

Dosage and Application

When diffusing lavender around cats, it’s crucial to use only small amounts. According to the ASPCA, lavender and other essential oils should be diluted to 0.5-1% before use around cats.

A safe dilution for a standard 100 mL diffuser would be 0.5 to 1 mL of lavender oil diluted in 99 to 99.5 mL of water. Always start with the lowest dilution of 0.5% and monitor your cat’s reaction before increasing the amount.

Only diffuse lavender for short periods of 15-30 minutes maximum per use. Make sure your cat is not trapped in the same room and can walk away if they don’t like the smell. Never diffuse oils continuously all day around cats.

It’s also important not to let the oils touch your cat’s skin, fur or paws directly. Wipe down any surfaces where oils could have condensed with soap and water.

According to PetMD, some veterinarians recommend placing the diffuser across the room from where your cat sleeps or spends most of their time, to allow adequate ventilation and dilution of the oils.

In summary, always use lavender oil safely around cats – diluted, in short diffusing durations, not continuously, and kept away from direct skin contact.[1]

Cats vs Other Pets

When it comes to using lavender around pets, there are some key differences between cats and other common household pets like dogs. Lavender contains a compound called linalool which can be toxic to both cats and dogs if ingested in large quantities. However, cats tend to be more sensitive to essential oils like lavender.

One study found that cats are uniquely deficient in the enzyme that helps metabolize linalool compared to other mammals like dogs and humans (source). This means cats’ bodies break down lavender more slowly, allowing it to build up to potentially toxic levels in their system. For this reason, lavender should always be used with greater caution around cats versus dogs.

In mild concentrations, brief exposure to lavender is generally not harmful to most pets. However, it’s recommended to avoid diffusing lavender oil around cats for extended periods of time or applying it directly onto their fur. Dog owners do not need to be quite as cautious, as studies show dogs can typically tolerate low-moderate levels of lavender without issue. But it’s still smart to minimize a dog’s exposure and monitor for any signs of irritation.

Overall, lavender should be used minimally around cats, if at all. While dogs appear less sensitive, it’s still wise to err on the side of caution and limit their exposure as well. Cat owners should be especially vigilant given cats’ unique metabolism of the key lavender compound linalool.

Owner Experiences

Many cat owners have shared their experiences using lavender around their cats. Some report that their cats seem to enjoy and be calmed by the scent of lavender. For example, one cat owner said “I tried a lavender scent cat repellent, but my cat adores it and sleeps near it” (source). Other owners have had less positive experiences, noticing respiratory issues or reactions in their cats when exposed to lavender. One owner asked “I recently bought a lavender diffused mattress topper (so when we sleep it releases a lavender scent) my cat was laying on the bed and started wheezing, is this caused by the lavender?” (source). Overall, experiences seem mixed, with some cats enjoying lavender’s aroma while others have adverse reactions.

Vet Recommendations

Veterinarians generally advise against using lavender around cats. According to the ASPCA, lavender plants and oils can be toxic to cats1. The lavender plant contains linalool and linalyl acetate, compounds that can cause gastrointestinal upset, lethargy, and skin irritation in cats. Inhaling lavender oil can also irritate a cat’s respiratory tract.

While some cat owners claim diffusing small amounts of lavender oil has calming effects, vets recommend erring on the side of caution. The safest approach is to avoid lavender plants and oils entirely. There are no definitive studies proving lavender’s safety for cats. Vets advise cat owners to use products specifically formulated for feline use when a calming scent is desired.

If a cat ingests part of a lavender plant or oil, immediately contact an emergency vet. Signs of lavender poisoning include drooling, vomiting, diarrhea, tremors, and lethargy2. With prompt treatment, cats can fully recover from lavender poisoning.

Oils to Avoid

Some essential oils are toxic and unsafe to use around cats. According to the ASPCA Poison Control Center, the top essential oils to avoid around cats include:

  • Wintergreen oil
  • Peppermint oil
  • Pine oil
  • Citrus oils like lemon, orange, etc. (contain d-limonene)
  • Eucalyptus oil
  • Clove oil
  • Ylang Ylang oil
  • Rosemary oil
  • Sandalwood oil

These oils can cause various symptoms in cats when inhaled or ingested, from drooling and vomiting to liver damage and neurological problems. It’s best to avoid diffusing or applying these oils directly around cats. Check with your vet before exposing your cat to any essential oil, even ones considered relatively safe.

Final Verdict

After reviewing the benefits and risks, my final recommendation for using lavender essential oil around cats is to exercise caution. Lavender oil does have calming properties that can be beneficial for some cats, but the chemical composition can also be an irritant for cats with sensitivities. Use only therapeutic-grade, high quality lavender oil, and always diffuse it in moderation. Start with very short exposure times (30 minutes or less per day) and watch your cat closely to evaluate their reaction. Some cats may show irritation like coughing or watery eyes. If you notice any concerning signs, immediately stop diffusing lavender in your home. It’s also wise to check with your veterinarian, as they can evaluate your individual cat and advise if lavender exposure seems appropriate. With careful precautions, some cats can enjoy the soothing benefits of lavender. However, it’s not worth the risk for cats with sensitivities. Evaluate your cat’s unique tolerance and adjust accordingly to make the safest choice for their health.
