Your houseplants share the same home with you, your kids, and your pets, so it’s vital to know whether any plants you own are toxic. Is ZZ plant toxicity something you should be worried about? Learn all about its toxicity and other properties in our guide.

How Poisonous Is ZZ Plant?

The ZZ plant is only mildly toxic. Unlike many other indoor plants, ingesting it isn’t normally fatal to humans, cats, or dogs. It’s often even omitted from most official lists of poisonous houseplants because of this.

Why Is the ZZ Plant Toxic?

The reason that the ZZ plant or Raven ZZ plant is considered to be mildly toxic is that it contains calcium oxalate, a crystalline salt present in a variety of different plants, including some that are used for food, like spinach. It isn’t poisonous but is an irritant that can cause a variety of symptoms, like skin inflammation and itching if touched and diarrhea and kidney stones if ingested.

Because touching the sap can cause a burning feeling on sensitive skin, keep your ZZ plant out of reach of your pets whenever possible.

Cats like to nibble on leaves occasionally, which is why your ZZ plant must stay out of their reach. Its sap can irritate your cat’s mouth, causing a burning and painful sensation. Another way your cat can get in contact with the toxins contained in the ZZ plant is by trying to sharpen its claws on it.

ZZ Plant Symptoms: What Happens If Your Cat or Dog Eats Part of a ZZ Plant?

If your cat or dog eats a ZZ plant’s leaf, stem, or root, it may first of all feel an unpleasant burning in its mouth. Depending on how much it has eaten, it can also experience digestive problems, diarrhea, and vomiting. It’s also possible that your pet will start scratching itself, drooling, or whimpering because of the unpleasant sensations it is experiencing.

Handling ZZ Plant Exposure in Pets

If your pet has ingested a part of the ZZ plant, don’t panic. Check your pet’s mouth for any pieces of the plant that you can remove. Wipe its mouth with a wet soft cloth and give it plenty of water to drink to dilute the toxins. You should contact your vet, as well, if your furry friend has serious symptoms.

Can I Touch My ZZ Plant?

If your skin comes in contact with the sap, wash your hands with soap immediately. Also, avoid rubbing your eyes or face until you’ve washed off all the sap. 

What to Do if a Child Eats ZZ Plant

If a child eats even a small part of the ZZ plant’s leaves or stems, here’s what to do. Remove any pieces from the child’s mouth and wipe it gently with a soft cloth. Give them some water to drink to wash off the remainder of the sap. Call your local poison helpline if you’re not sure how much of the plant the child has swallowed.
