Can Cats Eat Parsley? The Herb That's Surprisingly Risky

Parsley is a common garnish and cooking herb, but can cats eat parsley? The answer depends on the type of parsley — and one variety is actually toxic to cats. Here's what every cat owner needs to know.

Is Parsley Safe for Cats?

This is where it gets important: not all parsley is the same.

• Curly parsley (common parsley) — considered mildly toxic to cats by the ASPCA. It contains compounds called furanocoumarins that can cause photosensitivity and digestive upset.
• Spring parsley (Petroselinum crispum) — also listed as toxic to cats by the ASPCA.
• Italian flat-leaf parsley — similarly risky and best avoided.

The bottom line: all common varieties of parsley should be kept away from cats.

Symptoms of Parsley Toxicity in Cats

If a cat eats parsley, especially in larger amounts, symptoms may include:

• Vomiting and diarrhea
• Photosensitivity (skin sensitivity to sunlight)
• Lethargy
• Loss of appetite

A small accidental nibble is unlikely to cause a crisis, but regular exposure or larger amounts warrant a vet call.

What About Parsley Water or Parsley Supplements?

Parsley-infused water and parsley supplements marketed for pets do exist, but these are not recommended without explicit veterinary guidance. The concentration of active compounds can vary widely, and what's safe for dogs may not be safe for cats.

What to Do If Your Cat Eats Parsley

Monitor your cat for any symptoms. If they ate a significant amount or show signs of illness, contact your veterinarian. Keep your cat indoors and away from direct sunlight if you suspect photosensitivity.

It's always smart to have a pet first aid kit on hand:

👉 EVERLIT Pet Medic First Aid Kit (95 Pcs) — vet-approved, compact, and ready for any pet emergency.

Safe Plant Alternatives for Cats

If your cat loves chewing on greenery, give them something that's actually safe and designed for them:

👉 Wooden Cat Grass Planter with Potting Soil — a beautiful indoor cat grass planter with anti-digging grid.
👉 SmartyKat Sweet Greens Cat Grass Seed Grow Kit — easy to grow, safe for cats, satisfies their natural chewing instinct.

Final Thoughts

Parsley is not safe for cats — all common varieties are considered mildly toxic by the ASPCA. Keep parsley plants and parsley-containing foods away from your feline friend, and redirect their plant-chewing habit to safe cat grass instead.

Always consult your veterinarian if you're concerned about something your cat has eaten.
