is palo santo safe for cats?

Most of us like the feeling that a bubble bath or a glass of wine while sitting on the couch, eventually combined with aromatherapy, gives us when we are stressed. This form of relaxation that can help us relieve stress consists of burning incense sticks or scented candles, using essential oils or bath salts, and more.

A typical scented stick consists of a bamboo wood to which a fragrant powder of plants adheres, but there are also ready-to-burn, such as Palo Santo or “holy stick” (Bursera graveolens).The scent of this wood has notes of mint, citrus, and pine and is used for relaxation and purifying our space.

For cats, raw Palo Santo wood is not toxic if it is nibbled. Exposing them to the smoke, when is burning, can irritate their lungs. The only advantage Palo Santo has is that it is a good natural repellent for insects.

Regarding essential oils, it is advisable to use them when the cat is not around because they are concentrated extracts from plants, and most are harmful for our fluffs, including Palo Santo.

The majority of essential oils are bad for your cat, but there are some that are considered safe like lavender, copaiba, helichrysum, and frankincense oil.

Short description of Palo Santo

palo santo wood sticks and incense for cats

A Palo Santo tree is native to South America and belongs to the citrus family. The wood of the Palo Santo is available in the form of sticks, chips, or powder. It usually comes from the branches of the tree, so it is 100% natural. It also contains a very fragrant resin, which can be extracted and used separately. An analysis of Palo Santo essential oil showed that the main active constituents are limonene 89.33%, α-terpineol 11%, mentofuran 6.6%, and carvone 2%. (1)

The wood of the saints was used by indigenous people for spiritual ceremonies and healing – to relieve the symptoms of colds and flu, depression, emotional pain, and other ailments. It is said that its aroma induces relaxation and leads to meditation, but it also brings creativity and luck.

These benefits only exist when a Palo Santo tree dies naturally, and then it is allowed to decompose in five to eight years. In these years, the oil in the wood matures completely before being harvested and processed (this is why it is so expensive).

Palo Santo – Risks and Benefits for cats


Although Palo Santo is not poisonous to cats if they nibble it a bit, it contains d-limonene (a terpene found in most citrus peels), which is toxic. Depending on the concentration at which the pet is exposed (if it ingests wood or essential oil), according to the researchers, d-limonene poisoning shows the following clinical signs:

  • short or long-term hypersalivation,
  • digestive disorders,
  • ataxia,
  • shiver-like muscle tremors,
  • severe hypothermia,
  • irritation of the mouth,
  • and even death. (2)

This toxicity is due to the lack of the liver enzyme glucuronyl transferase – a compound that helps to eliminate the substances found in many essential oils, such as phenols, eugenols, and d-limonene, that cats do not have.

Also, wood consumption can lead to intestinal blockages once it reaches the digestive tract.

Exposure to smoke from burning Palo Santo wood (and smoke in general) can cause respiratory problems. Furthermore, its inhalation may result in irritation of the mouth and gums.

If cats with skin allergies come in contact with Palo Santo by ingesting the wood or essential oil, rub against the tree bark, or are in a room full of smoke, it can exacerbate their allergy.

Palo Santo essential oils are obtained by steam distillation of the fallen branches and dead trees. This unique chemistry does not occur when the trees are cut down. In other words, Palo Santo essential oil is a concentrated wood essence; therefore, it will have considerably higher amounts of d-limonene, which makes it unsafe for cats. Exposure to essential oils can irritate the whole body.

It is recommended to keep Palo Santo wood away from your cat’s prying eyes and sharp teeth. If you burn a stick from time to time, it is best to do it in a ventilated room.

Also, if you think your cat has ingested wood or has been exposed to the essential oil or smoke, go to the vet’s office immediately with your pet.


For some cats, Palo Santo wood stimulates play. They will nibble on it, purr, meow, and rub their head against it.

It is a good idea not to let your cat ingest it due to the medical complications that may occur later.

Burning Palo Santo wood won’t kill your cat, unless you set your house on fire! On the other hand, the smoke can cause asthma attacks and irritate the oral cavity and lungs.

Is Palo Santo spray/diffuser ok for my cat?

It is recommended not to use Palo Santo spray or a diffuser when your cat is nearby. The best you can do is to spray it when the cat is not around and let it sit for a while.

What About other Aroma Sticks and Oils?

Whether you use burning aroma sticks, essential oils, or diffusers, it is best to do this when the cat is in another room as it can cause your pet all sorts of reactions.

If your feline suffers from respiratory problems or skin allergies, it is recommended not to use any essential oils or aroma sticks at all because its health will deteriorate.

Are cats allergic to Palo Santo?

Like any other ingredients, you will know if your pet is allergic to something only when it comes in contact with it, and Palo Santo makes no exception!

If your cat already has a skin allergy it is better not to use incense sticks in its presence, as it can exacerbate its skin condition.

If your pet has asthma, try not to burn Palo Santo sticks or expose it to any other smoke because it can cause an asthma attack.

Which cat breeds are most affected by the incense smoke?

In general, short-nosed cat breeds are the most affected by smoke. They have shorter facial bones, and the soft tissues are modified- for this reason, the Persian, Himalayan, and Burmese breeds are the best known to have respiratory problems.

What should I do if my cat came in contact with Palo Santo?

If your cat inhaled too much smoke from your burning incense, ventilate the room, move your cat to a smoke-free area, open the windows or take it outside for fresh air. If you see any unusual behavior (sneezing too much, drooling, or showing signs of asthma attack) take your pet to the veterinarian as soon as possible.

If your cat ate too much wood or ingested essential oil and you see it trembling, vomiting, hypersalivating, or it does not coordinate its movements, take it to the veterinary clinic for the proper treatment and care.

Is Palo Santo similar to catnip?

These two plants are not related, but some cats react to Palo Santo as they do to catnip.

Cats will bite the wood, purr, meow, rub their face against it, and they will want to play – this is why it is said that Palo Santo stimulates play.

Palo Santo Vs. Sage

Unlike Palo Santo, sage is safe for cats (along with basil) – cats can ingest it without any toxic effects to them. However, be careful not to expose your kitty to the essential oils (either directly or through a diffuser). As we mentioned at the beginning of the article, cats lack the liver enzyme that breaks down chemicals found in essential oils, so even a low dose can be considered harmful.

Is Peppermint or Patchouli Incense Safe For my Fluffy Pets?

Peppermint plant is considered poisonous to cats – skin exposure and ingestion can be toxic for our felines. It is poisonous whether applied directly to the skin, used in diffusers, or a drop was licked from the ground. Therefore, do not use peppermint incense sticks or essential oils as they are very harmful to your cat.

Patchouli plant is related to mint (like catnip), but is not safe for cats. Mint-based essential oils and aromas contain chemicals that are too strong for our little cats, making them difficult for their bodies to process.

Unlike peppermint, patchouli is not considered toxic, but the likelihood of strong side effects on your cat’s health is high.

Can I use air fresheners for my cat?

In general, air fresheners are composed of over 100 chemicals, including volatile organic compounds (such as limonene) – that is why it is recommended to use them when your cat is not in the room. Do not apply it directly on your pet or allow your cat to lick the product!

It is best to use pet-friendly air fresheners, such as Feliway, Enviroscent Plug-in Air Freshener Kit, Mrs. Meyer’s Room Freshener and other because they contain natural fragrances.

Are scented candles safe for my cat?

scented candles for cats

Cats have a very sharp sense of smell, and the strong scents bother most of them; therefore, they may avoid the rooms where fragranced candles are used. However, if your cat is nearby, make sure the room is well ventilated so that the fumes and smell of the candle do not cause problems to your pet.

Regardless of the candle type (natural or artificial, scented or not), there is always the risk that your cat will flip it and burn itself or even set the house on fire. So, be careful!

Best and Worst essential oils and incense sticks for Cats

No matter what essential oil you choose to use, all of them have the potential to be dangerous to our cats, but there are some that are considered safer, such as:

  • lavender,
  • copaiba,
  • helichrysum,
  • jasmine,
  • cedarwood,
  • vetiver,
  • eucalyptus,
  • and frankincense oil.

It is best to use them in a diffuser, as they are very dilute this way.

The following plants or essential oils should be avoided:

Peppermint – raw peppermint and essential oil are poisonous to cats because it contains phenols, which are very harmful to our little felines.

Lemongrass – raw lemongrass is safe for cats, but in small quantities; Lemongrass essential oils can be fatal to cats.

Tea tree essential oil can be poisonous to cats if it is not diluted or if the dose is too high (before it is applied to the skin). Although tea tree oil was once considered a safe remedy for fleas, it is now recommended not to use it in cats.

Lavender plants and essential oils are toxic to cats if ingested and can cause nausea and vomiting.

Chamomile, in small doses, is considered quite safe for cats, but if ingested in large quantities or long-term it can be harmful to your cat. It contains a wide range of toxic substances for our little felines, such as tannic acid, anthemic acid, chamazulene, bisabolol, and volatile oils. (3)

Rosemary – although fresh rosemary leaves can’t cause any damage for cats, the essential oil is harmful to them.

Thyme – like peppermint, it contains phenols, which are dangerous to your cat and can make it sick.
