Is Rosemary Toxic to Cats?

Published in Pet Plant Toxicity 3 mins read

No, rosemary is generally considered non-toxic to cats. This aromatic herb, a popular addition to many gardens and kitchens, is also deemed safe for dogs and horses.

Understanding Rosemary's Safety for Felines

According to leading animal poison control information, rosemary (scientific name: Salvia rosmarinus) does not pose a significant toxic threat to cats. This means that if your curious feline takes a nibble of a rosemary plant, it's unlikely to cause severe poisoning.

While classified as non-toxic, it's always a good practice to prevent pets from consuming large quantities of any plant material. Ingesting an excessive amount of even a non-toxic substance can sometimes lead to mild digestive upset, such as vomiting or diarrhea, simply due to the plant matter itself.

Other Lamiaceae Family Members: What to Watch Out For

Interestingly, while rosemary is safe, some other common herbs belonging to the same Lamiaceae (mint) family are considered toxic to cats. It's crucial for pet owners to be aware of these distinctions to ensure their home environment is safe for their furry friends.

Here are some Lamiaceae family members that pet owners should keep away from cats:

  • Catnip: Paradoxically, despite its well-known stimulating effects on cats, catnip is listed as toxic. While many cats react positively to it, large ingestions could potentially cause mild issues.
  • Lavender: Known for its soothing aroma, lavender plants can be toxic if ingested by cats.
  • Marjoram: This culinary herb is also identified as potentially harmful to felines.
  • Mint: Various species of mint can be toxic to cats, leading to gastrointestinal upset.
  • Oregano: A common kitchen staple, oregano should also be kept out of reach from cats.

Safe vs. Unsafe Herbs for Cats

To help pet owners easily identify which common herbs from this family are safe and which are not, here's a quick reference:

Herb Toxicity Status for Cats Notes
Rosemary Non-toxic Generally safe; avoid excessive ingestion.
Catnip Toxic Can cause mild issues despite common use.
Lavender Toxic Keep away from curious felines.
Marjoram Toxic Can lead to gastrointestinal upset.
Mint Toxic Various mint species are harmful.
Oregano Toxic Another common culinary herb to avoid ingestion.

What to Do If Your Cat Ingests a Plant

If you suspect your cat has ingested any part of a plant, especially one known to be toxic, or if they show any signs of illness (such as vomiting, diarrhea, lethargy, or changes in behavior), it's always best to contact your veterinarian or a pet poison control center immediately. For reliable information on toxic and non-toxic plants, resources like the ASPCA Animal Poison Control Center are invaluable.

Taking proactive steps to identify and remove potentially harmful plants from your cat's environment is the best way to ensure their safety and well-being.
