Mint is one of the most recognizable herbs in the world. It’s used in teas, candies, chutneys, toothpaste, desserts, medicines, and even household products. Many homes also grow mint plants in balconies or kitchens. Because mint has such a strong, refreshing smell, cats often react to it by sniffing, rubbing, pawing, or even trying to chew the leaves.
This leads to the big question:
Can cats eat mint safely?
The answer is more complicated than basil, parsley, or cilantro, because some types of mint are safe, but others are toxic.
This guide explains everything you must know about mint and cats — including which types are safe, which are dangerous, how much is okay, symptoms of mint poisoning, and safe alternatives you can use instead.

Is Mint Safe for Cats?
The term “mint” refers to a broad group of plants. Some are safe in tiny amounts, while others can be toxic.
✔ Safe-ish (in tiny amounts):
- Spearmint (Mentha spicata)
- Peppermint (Mentha × piperita) — only tiny amounts
✘ Unsafe or toxic to cats:
- Pennyroyal mint (Mentha pulegium) — highly toxic
- Essential oils of any mint — toxic
- Mint-based balms, rubs, sprays, oils
So, while some types of mint leaves are non-toxic, the overall mint category requires caution.
Mint is not deadly in most cases, but cats can experience stomach upset, vomiting, diarrhea, and in some cases, neurological symptoms if the wrong type or too much is consumed
Why Are Some Mints Toxic to Cats?
Mint contains essential oils, especially:
- Menthol
- Pulegone
- Limonene
Cats’ livers cannot process essential oils effectively because they lack the necessary detoxification enzymes.
Even “safe” mint plants contain these compounds — just in lower levels.
Do Cats Like Mint?
Many cats are attracted to the smell of mint because it can mimic catnip. Catnip (Nepeta cataria) is part of the mint family, and some cats react similarly to spearmint or peppermint.
Cats may:
- Sniff mint intensely
- Rub their face against mint leaves
- Paw at mint
- Try to chew mint plants
- Roll around near mint
This reaction is sensory-based, not nutritional.
However, interest does NOT mean mint is good for cats.
Health Benefits of Mint for Cats (Minor and Not Necessary)
Mint is known for digestive and soothing benefits in humans, but cats cannot extract the same level of nutrients or effects.
Still, tiny amounts may offer:
1. Slight stomach-soothing effects
Spearmint leaves may help with minor digestive discomfort — but this is extremely mild in cats.
2. Breathing freshening (small effect)
The menthol aroma may provide a temporary fresh breath effect.
3. Enrichment via scent
Some cats enjoy the smell as sensory enrichment.
However, these benefits are so minimal that mint is never needed in a cat’s diet.
Risks of Mint for Cats
Mint comes with several serious risks if not managed properly.
1. Digestive Upset
Mint leaves can irritate a cat’s stomach. Symptoms include:
- Vomiting
- Diarrhea
- Drooling
- Gas
- Stomach pain
This is the most common side effect.
2. Pennyroyal Mint Is Highly Toxic
Pennyroyal contains pulegone, a compound that can cause:
- Liver damage
- Internal bleeding
- Collapsing
- Death (in severe cases)
Never grow pennyroyal in a home with cats.
3. Mint Essential Oil Is Toxic
Mint essential oils (peppermint oil, spearmint oil) should NEVER be used around cats. They can cause:
- Breathing difficulty
- Drooling
- Tremors
- Liver toxicity
- Seizures
Even diffused oil can be dangerous.
4. Mint Plants May Cause Skin Allergies
Some cats experience skin irritation after touching strong mint leaves.
5. Exposure Through Human Products
