Which Essential Oils Are Toxic to Cats?

Essential oils are highly concentrated plant oils that have unique chemical properties. They are often used for their therapeutic and aromatic qualities and have been touted as natural remedies for many ailments. While essential oils may have beneficial properties, they can also be toxic to cats. Essential oil toxicity can occur when a cat is exposed to the oil directly, inhaled, orally ingested, or by contact with broken skin. This article will discuss which essential oils are toxic to cats, symptoms of toxicity, and what to do if you think your cat has been exposed to an essential oil.

The vast majority of essential oils are safe for cats in small amounts and when properly diluted. However, it is important to remember that even the most natural products can be harmful to cats if they are used incorrectly or in large doses. For example, if an undiluted essential oil is rubbed into the skin or inhaled it can cause a variety of problems including irritation, burns, seizures, respiratory distress, gastrointestinal upset, and liver damage.

Undiluted essential oils are dangerous to cats because they are so strong and can quickly irritate and overwhelm the delicate tissues of a feline. This is true whether the oils are applied directly to the skin or inhaled from a diffuser. Essential oils that are inhaled can be absorbed through the lungs, and if inhaled for long periods of time, they can lead to a variety of complications including respiratory failure, depression or lethargy, loss of coordination, nervous system signs such as tremors, weakness, or unsteadiness, gastrointestinal distress (vomiting or diarrhea), respiratory distress, low body temperature, rapid heart rate, and even death.

It is important to keep in mind that there is very little published experimental data regarding the toxicity of pure essential oils in animals. This is due to the wide range of compounds that make up essential oils and the difficulty in performing experiments with them because it would require exposing animals to potentially fatal substances.

Unlike humans, cats do not have the enzymes necessary to metabolize certain chemicals in some essential oils. These chemicals, known as phenols, are particularly concentrated in some oils and can have a profoundly negative effect on the liver and other organs.

When a cat inhales essential oils, they are rapidly absorbed into the bloodstream and pass through the kidneys and liver where they can cause toxicity. Signs of toxicity in cats include depression or lethargy, tremors, seizures, gastrointestinal upset, vomiting, respiratory distress, hypothermia, and liver failure.

If a cat is exposed to essential oils, it is critical to seek immediate veterinary care. A veterinarian can perform blood work to determine if the liver and kidneys are affected. Treatment for essential oil toxicity is usually supportive, with fluid therapy, nebulized medications for breathing support, stomach protectants, pain control and medications to help the liver.

As a cat owner, you know your pet best and should always monitor them for signs of discomfort or illness. If your cat seems lethargic or if you see them showing signs of respiratory distress, neurological signs such as confusion or unsteadiness, or if they have a rash or red areas on their skin or mucous membranes contact your local vet immediately.
