What Is Aglaonema and Why Is It Toxic to Cats?
Aglaonema, also called Chinese Evergreen, is a popular indoor plant known for its striking variegated leaves and easy care. It thrives in low light and comes in many colorful varieties.
While beautiful, aglaonema belongs to the Araceae family and contains insoluble calcium oxalate crystals in its stems and leaves. These crystals are precisely what make the plant toxic to cats. When a cat chews on aglaonema, the crystals break off into the mouth and throat, causing immediate pain and swelling.
In homes where pets and plants coexist, awareness is essential.Cats are naturally curious creatures and often use their mouths to explore their surroundings. Because aglaonema doesn’t emit a strong odor or have a bitter coating, it may not immediately deter a curious feline. The danger lies in that one accidental nibble is enough to cause discomfort. Educating yourself on the risks is the first step in building a safe environment for your pet.

Aglaonema Toxic to Cats: Signs and Symptoms
If you suspect your cat has nibbled on aglaonema, watch closely for warning signs. Symptoms of aglaonema poisoning usually appear quickly, often within minutes.
Common Symptoms of Aglaonema Poisoning in Cats
- Oral irritation and pain (swollen, red mouth or tongue)
- Excessive drooling or foaming at the mouth
- Pawing at the mouth or face
- Vomiting and diarrhea
- Loss of appetite or refusal to eat
- Difficulty swallowing or breathing
In most cases, these symptoms are unpleasant but not life-threatening if treated quickly. However, if large amounts of the plant were eaten, watch for more serious reactions. Rapid, shallow breathing and severe gastrointestinal upset may require emergency care.
Beyond the immediate symptoms, be alert for subtle changes in behavior. Your cat may hide more often, avoid food bowls, or vocalize in discomfort. Any behavioral shift, especially after recent exposure to plants, should be treated seriously. Taking photos or notes of symptoms can be helpful when consulting with a veterinarian.
What to Do If Your Cat Eats an Aglaonema Plant
If your cat ate aglaonema, stay calm and act fast. Most cats recover with prompt care. Here’s what you should do:
- Remove the plant from your cat’s reach.
- Rinse your cat’s mouth with cool water.
- Do NOT induce vomiting unless a vet advises it.
- Call your veterinarian immediately.
- Monitor your cat for worsening symptoms.
Quick action and professional advice lead to the best outcomes. In most cases, cats recover fully from aglaonema poisoning.
It’s helpful to know your nearest emergency vet location and keep their contact information accessible. A pet first aid kit that includes saline rinse, gloves, and a dosing syringe can also be useful in handling minor exposures. Planning ahead ensures you’re not scrambling during a stressful situation.
Other Plants Toxic to Cats Like Aglaonema
Aglaonema isn’t the only plant that poses a threat. Other toxic houseplants include:
- Philodendron
- Pothos (Devil’s Ivy)
- Dumb Cane (Dieffenbachia)
- Peace Lily
- Arrowhead Vine
- Sago Palm
- Lilies (extremely toxic)
These plants also contain oxalates or other harmful compounds. Even a small nibble can result in severe reactions, especially with lilies and sago palms.
Toxic plants aren’t always exotic. Everyday garden plants like tulips, daffodils, and even certain herbs can pose dangers. It’s easy to overlook these risks when shopping for home decor or garden supplies. As a pet owner, having a go-to list of safe plants is a wise habit.

Plant | Safe for Cats? | Notes |
---|---|---|
Chinese Evergreen (Aglaonema) | ❌ No | Contains calcium oxalate crystals; causes oral irritation and vomiting. |
Spider Plant (Chlorophytum) | ✅ Yes | Non-toxic and safe. |
Aloe Vera | ❌ No | Can cause vomiting and diarrhea. |

Creating a “green corner” just for your cat can keep them happy and curious without risk.
How to Keep Cats Safe From Toxic Plants
Prevention is key when it comes to keeping your cat safe from toxic plants like aglaonema. Here are some effective tips:
- Keep your plants safe by placing them on tall shelves or hanging them where your cat can’t get to them.
- Use plant covers such as terrariums or decorative cages.
- Spray bitter scents like lemon or orange around plant bases.
- Provide alternative greens like cat grass or catnip.
- Entertain your cat with toys and interaction to reduce boredom chewing.
- Check plant safety before buying to ensure it’s non-toxic.
Another useful strategy is using motion-sensitive deterrents near high-risk areas. These can startle cats gently when they approach restricted zones, helping them associate plants with “off-limits” zones. Over time, this encourages safe habits and protects both pets and plants.
