A little kitchen herb garden is a whole vibe — fresh basil, pretty pots, that “I have my life together” energy. But if your cat likes to sample your windowsill, you need to know which herbs are safe and which are a hard no (some are genuinely dangerous). Here’s the cat-safe herb rundown.
✅ Cat-safe herbs
These are ASPCA non-toxic to cats (verify any specific plant on the ASPCA database):
- Basil — non-toxic; a curious nibble is fine.
- Rosemary — non-toxic and pretty pet-safe.
- Thyme & sage — non-toxic in normal amounts.
- Cilantro (coriander) — non-toxic.
- Dill — non-toxic.
Note: “non-toxic” means not poisonous, not “should be a snack” — a cat gorging on any herb can get a mild upset stomach.
⛔ Herbs to avoid
| Herb | Why |
|---|---|
| Chives, garlic, onion, leeks (Allium family) | Toxic — damage red blood cells; can be serious |
| Mint (large amounts) | Can cause GI upset; peppermint essential oil is worse |
| Oregano | Can cause GI upset in larger amounts |
| Lavender (the plant) | Mildly toxic; lavender essential oil is toxic to cats |
The big one: never grow chives, garlic, or onions where your cat can reach them — the Allium family is genuinely toxic. And skip essential oils entirely around cats.
Herbs cats actually love
Some herbs are cat-approved treats: catnip (the classic “high”), catmint, valerian, and cat grass (cereal grasses). Growing these gives your cat a safe, enriching thing to munch — and keeps them out of your basil.
Grow them a safe green
The easiest peace treaty between your herb garden and your cat: give the cat its own greens. A tray of cat grass satisfies the chewing instinct so your kitchen herbs stay intact.
A safe green for your cat to graze so your herb garden stays yours. Sprouts in days — here’s how to grow it.

Is basil safe for cats?
Yes — basil is ASPCA non-toxic. A nibble is fine; a huge amount could cause mild stomach upset like any plant.
Are chives or garlic safe for cats?
No — the Allium family (chives, garlic, onion, leeks) is toxic to cats and can damage red blood cells. Keep them out of reach entirely.
Is mint toxic to cats?
Small amounts of the plant are usually just mildly upsetting, but peppermint essential oil is toxic. Don’t diffuse mint oils around cats.
What herbs can I safely grow with a cat?
Basil, rosemary, thyme, sage, cilantro, and dill are non-toxic — plus cat-approved catnip, catmint, and cat grass.
The bottom line
Most cooking herbs — basil, rosemary, thyme, sage, cilantro, dill — are cat-safe. The hard no’s are the Allium family (chives, garlic, onion) and essential oils. Want total peace? Grow your cat its own catnip and cat grass so your kitchen herbs stay off the menu.
