Are ZZ Plants Toxic to Cats? What Every Pet Parent Needs to Know Before It’s Too Late

You bring home a gorgeous new houseplant that seems impossible to kill and looks impressive in any corner of your home. A ZZ plant. Shiny leaves, deep green color, low maintenance… it’s plant perfection.

But then your cat walks up, sniffs it, and gives it that look—the one that says, “I’m going to chew this just to see what happens.”

If you’ve found yourself typing are ZZ plants toxic to cats in a mild panic, you’re not alone. Many pet parents worry about their plants, especially when their curious feline friends see them as toys or snacks.

Let’s talk about the real risks, what symptoms to look out for, and how to keep your cat and plants safe.

First Things First: Yes, ZZ Plants Are Toxic to Cats

Unfortunately, the answer is yes. ZZ plants (Zamioculcas zamiifolia) are toxic to cats. Every part of the plant—leaves, stems, and roots—contains calcium oxalate crystals, which can irritate your cat’s mouth and stomach and even cause more serious reactions if enough is ingested.

Now, does this mean your cat is going to collapse after a nibble? Not likely. But even a small bite can lead to some uncomfortable symptoms.

So, while ZZ plants won’t usually be fatal, they’re not feline-friendly.

What Happens If a Cat Chews on a ZZ Plant?

If your cat takes a nibble, you might notice some of the following signs:

• Drooling
• Pawing at the mouth
• Vomiting
• Decreased appetite
• Swelling of the lips, tongue, or mouth
• Whining or acting unusually quiet

Calcium oxalate crystals are tiny, sharp particles that embed themselves in the soft tissues of the mouth and throat. That’s why one bite can lead to drooling or mouth discomfort.

Most of the time, the reaction is mild and passes within a day. But in rare cases, if a cat eats a larger amount or is sensitive, it could lead to more serious symptoms.

Real Talk: Will It Kill My Cat?

Highly unlikely. There are no widely reported deaths from ZZ plant ingestion in cats. But that doesn’t mean it’s harmless.

Think of it like this: it’s not poison in the sense of instant danger, but it’s still irritating, uncomfortable, and not something you want your cat dealing with.

If your cat is older, has a weak immune system, or already has a sensitive stomach, the reaction might hit harder.

And let’s be honest—none of us want to see our pet drooling in pain or throwing up, even if it’s temporary.

What Should You Do If Your Cat Eats a ZZ Plant?

Here’s a quick step-by-step:

1. Stay Calm

Easier said than done, but try. A little nibble is rarely serious.

2. Check Their Mouth

Look for redness, swelling, or excessive drooling. If your cat lets you, check if any plant bits are still in their mouth and gently remove them.

3. Offer Water or Rinse the Mouth

If they’re drooling a lot, offer water. You can also gently wipe or rinse their mouth using a clean, damp cloth (not forcefully). This helps get rid of the crystals causing irritation.

4. Watch for Vomiting or Lethargy

Most cats bounce back quickly, but call your vet if your kitty starts vomiting repeatedly, seems very tired, or refuses to eat.

5. Call the Vet If You’re Worried

Even if symptoms seem mild, there’s no harm in asking your vet for advice. A quick call can give you peace of mind.

Should You Get Rid of Your ZZ Plant?

Not necessarily.

If you can place it in a high spot or a room your cat doesn’t access, keeping it might still be possible. But if your cat is a determined climber or chewer, it’s probably not worth the risk.

Some people keep their ZZ plant inside a terrarium or behind glass—a smart move if you love the plant but want peace of mind.

If your cat is always looking for new leaves to chew, swapping your ZZ for a cat-safe plant might be better.

Cat-Safe Alternatives to ZZ Plants

Looking for greenery that won’t hurt your cat? Try one of these:

• Spider Plant – Non-toxic and fun for cats to bat around.
• Areca Palm – Safe and adds a tropical feel.
• Calathea (Prayer Plant) – Pet-friendly and beautiful.
• Parlor Palm – Gentle on cats and perfect for low light.
• Bamboo Palm – Safe, leafy, and low-maintenance.

These options let you enjoy houseplants without stressing over your curious little furball.

How to Cat-Proof Your Houseplants

Even non-toxic plants can cause tummy trouble if eaten in large amounts. So here’s how to keep your cat away from any plant:

1. Use Citrus or Bitter Sprays

Cats usually hate the smell of citrus. A gentle pet-safe deterrent spray can do wonders.

2. Aluminum Foil or Double-Sided Tape

Place foil or sticky tape around the base of your plant. Most cats don’t like the texture and will avoid it.

3. Create a Cat Garden

Give your cat their safe plants like cat grass or catnip. This distracts them from going after your other greenery.

4. Keep Plants in Hanging Pots or High Shelves

Out of sight, out of reach.
