Is rosemary extract safe for cats

As cat owners, we are always concerned about the safety and well-being of our feline friends. With the increasing popularity of natural remedies and holistic approaches to pet care, many cat owners are turning to herbal supplements and extracts to enhance their cats’ health. One such herb that has gained attention is rosemary extract. In this article, we will delve into the question: Is rosemary extract safe for cats?

The Basics of Rosemary Extract

Rosemary (Rosmarinus officinalis) is a fragrant herb that has been used for centuries in cooking, aromatherapy, and traditional medicine. It is native to the Mediterranean region and is known for its distinctive aroma and flavor.

When it comes to cats, rosemary extract is often used as a natural preservative in commercial pet foods and treats. It is believed to have antioxidant properties and can help prevent the spoilage of food by inhibiting the growth of bacteria.

Understanding Cat Physiology

Before we can determine whether rosemary extract is safe for cats, it’s important to understand their unique physiology. Cats are obligate carnivores, which means they require a diet primarily composed of animal protein. Their digestive systems are designed to process meat efficiently, but they lack certain enzymes necessary to metabolize certain compounds found in plants.

This difference in metabolism between cats and humans is why some foods that are safe for us can be toxic to our feline companions. It’s crucial to consider these physiological differences when evaluating the safety of any herbal supplement or extract for cats.

Is Rosemary Extract Safe for Cats?

The safety of rosemary extract for cats is a topic of debate among experts. While there isn’t a definitive answer, it’s important to consider the available scientific research and expert opinions.

Expert Opinions

According to the American Society for the Prevention of Cruelty to Animals (ASPCA), rosemary is listed as a plant that is potentially toxic to cats. The essential oil derived from rosemary contains compounds like camphor and 1,8-cineole, which can be harmful to cats when ingested in large quantities.

However, it’s worth noting that the ASPCA’s list includes plants that are toxic in large amounts but may not necessarily pose a risk when used in small quantities or as a preservative in commercial pet foods.

Scientific Studies

While there is limited scientific research specifically focused on the effects of rosemary extract on cats, some studies have explored the potential benefits and risks of rosemary in general.

A study published in the Journal of Ethnopharmacology found that rosemary extract exhibited antioxidant properties and had potential anti-inflammatory effects in rats. However, it’s important to remember that animal studies may not always translate directly to cats.

Another study published in Toxicology Reports examined the toxicity of rosemary extract on mice. The study found that high doses of rosemary extract could cause liver damage in mice. However, it’s important to note that mice and cats have different metabolic systems, so caution should be exercised when applying these findings to feline health.

The Potential Risks

While there isn’t conclusive evidence about the safety of rosemary extract for cats, it’s essential to be aware of potential risks associated with its use.

  • Allergic Reactions: Cats can develop allergies to various substances, including plants. Some cats may exhibit allergic reactions such as skin irritation or gastrointestinal upset when exposed to rosemary extract.
  • GI Upset: Cats have sensitive digestive systems, and introducing new substances can sometimes lead to gastrointestinal upset, including vomiting and diarrhea.
  • Neurological Effects: Compounds like camphor found in rosemary extract have the potential to affect the central nervous system of cats. Ingesting large quantities could lead to symptoms such as tremors, seizures, or even coma.

Safe Alternatives and Precautions

If you’re concerned about the safety of rosemary extract for your cat but still want to incorporate natural remedies into their routine, there are safe alternatives available. It’s always best to consult with your veterinarian before introducing any new supplements or extracts into your cat’s diet.

  • Cat-Safe Herbs: There are several herbs that are generally considered safe for cats, such as catnip, chamomile, and valerian root. These herbs can be used in moderation and under veterinary guidance for various purposes.
  • Natural Antioxidants: Instead of relying solely on rosemary extract as a preservative, look for cat foods that use other natural antioxidants like vitamin E or tocopherols.
  • Monitor Your Cat: Pay close attention to your cat’s behavior and overall well-being when introducing any new substance. If you notice any adverse effects, discontinue use immediately and consult your veterinarian.


The question of whether rosemary extract is safe for cats doesn’t have a straightforward answer. While some experts caution against its use due to potential toxicity, there is limited scientific research specifically focused on cats. As responsible cat owners, it’s important to consider the available information, consult with our veterinarians, and make informed decisions about our cats’ health and well-being.

Ultimately, every cat is unique, and what may be safe for one cat might not be suitable for another. By staying informed, seeking professional advice, and observing our cats’ reactions, we can provide them with the best possible care while celebrating their individuality and unique needs.
