Herbs not only offer culinary and medicinal benefits to humans but can also benefit our feline friends. If you’re a pet parent, you might be surprised to learn that there are several herbs that are safe for cats. Creating a cute little cat garden with these herbs can provide both visual appeal and potential health advantages. Let’s explore which herbs are safe for cats, and which ones should be avoided.

Herbs Safe for Cats

While the following herbs have generally been found to be safe for most cats, it’s still recommended to consult your veterinarian before introducing significant or regular usage.

Valerian is a lesser-known alternative to catnip and silver vine. This pungent herb acts as a stimulant for cats, transforming even the laziest (read: chubbiest) cats into the feline equivalent of Richard Simmons. Consider adding valerian to your indoor cat garden. Interestingly, valerian is also used among humans for relaxation purposes.

Witch Hazel

Believe it or not, veterinarians sometimes suggest using witch hazel to treat feline acne. Simply dampen cotton balls with witch hazel and gently wipe your cat’s chin once or twice a day.


Echinacea Plant

Culinary Herbs

These herbs may not offer specific medicinal benefits, but they are flavorful and safe for felines:

  • Basil
  • Cilantro/Coriander
  • Dill
  • Rosemary
  • Thyme


Catnip Plant

Of course, we can’t forget about catnip! This member of the mint family contains an essential oil called nepetalactone that drives many cats wild. However, not all cats carry the catnip-reacting gene.

It’s important to note that if a cat consumes large quantities of catnip (or any garden mint variety), it may lead to vomiting and diarrhea. Always supervise the amount of loose catnip or catnip buds your cat is exposed to.

Herbs to Avoid

Garlic and Chives

Garlic and chives pose the greatest danger to cats. In fact, all members of the allium family—including onions, leeks, scallions, and shallots—are toxic to felines. Even a small ingestion of these herbs can damage a cat’s red blood cells, potentially leading to anemia or even death.

Marijuana Plant

While Bob Marley’s statement that “herb is the healing of a nation” may hold true for humans, it’s not the case for cats. Marijuana is toxic to both cats and dogs. Ingesting any form of the plant, including edibles and tinctures, may result in symptoms such as prolonged depression, vomiting, incoordination, sleepiness or excitation, hypersalivation, dilated pupils, low blood pressure, low body temperature, seizure, coma, and rarely, death.


German Chamomile Plant

While many sites list chamomile as safe for cats, this is a dangerous generalization. Some types of chamomile are toxic to both cats and dogs. While German chamomile is considered safe, other variations, such as English, Garden, Roman, and True chamomile, can cause contact dermatitis, vomiting, diarrhea, anorexia, and allergic reactions in pets.

St. John’s Wort

If your cat spends time outdoors, avoid growing St. John’s Wort where they can consume it. Ingesting enough of this herb can cause photosensitization in pets, leading to ulcerative and exudative dermatitis.

Other Herbal Irritants

Avoid growing the following herbs in your cat garden, as they can cause vomiting and diarrhea in pets:

  • Lemongrass
  • Mint
  • Oregano
  • Tarragon

Before trying any herbs safe for cats, it’s essential to consult with your veterinarian. You can also check out the complete list of toxic and non-toxic plants and herbs for cats provided by ASPCA.

Remember, a healthy and happy cat is a cherished companion. So, go ahead and create a safe and appealing cat garden full of herbs that will provide both enjoyment and potential health benefits.
