Yes, aglaonema (Chinese evergreen) is toxic to cats; calcium oxalate crystals trigger mouth pain, drooling, vomiting, and swelling.
You care about plants and your cat. The big question—are aglaonema plants toxic to cats? Yes. The sap packs needle-like crystals that sting the mouth and throat. Most cases stay mild to moderate. Quick action at home and timely vet care keep things on track.
What Aglaonema Is And Why Cats React
Aglaonema, often sold as Chinese evergreen, sits in the Araceae family. The leaves and stems contain insoluble calcium oxalate crystals, called raphides. When a cat chews a leaf, those tiny spikes press into the gums and tongue. The result is sharp pain, drooling, pawing at the face, and a cat that wants nothing more than to spit and pull away.
The crystals act mechanically. They don’t pass into blood in a way that causes liver or kidney failure. The main worry is local injury, swelling, and fluid loss from heavy drooling or vomiting. Kittens, seniors, and cats with airway trouble need quick attention, since swelling can escalate faster in small or fragile patients.
Cat Symptoms After Aglaonema And First Aid
Chewing even a small piece can spark a big reaction. Look for sudden drooling, licking lips, gagging, retching, or a meow that sounds different. Some cats paw at the mouth or refuse food. Eye contact with sap can cause redness and squinting. Skin contact can tingle or itch. You asked, are aglaonema plants toxic to cats? Yes—and the signs usually start fast.
First aid starts with gentle decontamination. Offer a small amount of fresh water to sip. Rinse the mouth by loading a syringe with lukewarm water and letting it dribble along the cheeks, not straight down the throat. Do the same for eyes with sterile saline if available. Keep your cat calm and indoors. Save a leaf or snap a photo of the plant for the vet.
Aglaonema Exposure Cheat Sheet
| Exposure | Likely Signs | Onset |
|---|---|---|
| Quick nibble on a leaf | Drooling, lip licking, pawing at mouth | Within minutes |
| Several bites chewed | Drooling, gagging, vomiting, refusal to eat | Minutes to 30 minutes |
| Stem chewed (more sap) | Marked mouth pain, swelling, repeated vomiting | Minutes |
| Sap on tongue/gums | Burning pain, head shaking, whining | Immediate |
| Sap in eye | Redness, squinting, tearing, rubbing | Immediate |
| Sap on skin | Itch, redness, mild rash | 10–60 minutes |
| Large chew, small kitten | Heavy drool, repeated vomit, listless | Minutes |
| Allergic-type sensitivity | Hives or face puffiness | Minutes to 1 hour |
| Chronic small bites | On-off drool, low appetite, mild weight loss | Over days |
| Airway swelling warning | Noisy breath, panting, open-mouth breathing | Minutes—urgent |
Severity hinges on how much was chewed, sap exposure, and your cat’s size. Mouth pain tends to peak within an hour. Many cats bounce back within a day once the mouth settles, as long as they can drink and keep food down.
Are Chinese Evergreen Plants Poisonous To Cats? Signs And Safety Steps
Yes. Chinese evergreen is the same plant group. The crystal load varies by variety, yet the response looks similar across the range. You can verify plant status on the ASPCA Chinese Evergreen listing. That page names the plant as toxic to cats and dogs due to insoluble calcium oxalates.
Practical steps at home help: move the plant away, rinse the mouth, offer a little water or tuna juice, and watch breathing. If vomiting repeats, or your cat refuses to swallow saliva, ring your clinic. Bring a leaf sample or a clear photo for quick ID.
When To Call A Vet
Call now if any of the following show up: open-mouth breathing, wheeze, repeated vomiting, drool you can’t keep up with, weak stance, or a cat that hides and won’t sip water. Kittens under six months, seniors, and cats with heart or airway disease should be seen sooner rather than later.
Share the plant name, how much was chewed, when it happened, and what you’ve done already. If you used a mouth rinse, say how much. If you gave any meds, list the dose. Photos of the plant and the chewed leaf save time at triage.
What A Vet May Do
Clinic care aims to ease pain, control nausea, and protect airways. A vet may repeat the rinse under better light, treat pain with a fast-acting shot, and give an anti-nausea drug. Dehydrated cats receive fluids under the skin or by IV. Severe swelling can call for oxygen and close watching. Eye exposure earns a longer saline flush and a stain test to rule out scratches.
Blood tests usually look normal, since this plant acts locally. If signs don’t match the story, imaging can check for a string, bone, or other foreign body. Most cats go home the same day once drooling slows and swallowing looks steady.
How Vets Sort Out Look-Alikes
Many houseplants share this crystal-based sting. Dieffenbachia and philodendron cause near-identical mouth pain. Peace lily fits too. A vet checks leaf shape, stem texture, sap color, and your photos to pin the source. The pattern of pain without organ failure keeps the list short. Sudden collapse or black stool points away from aglaonema and calls for a wider search.
Recovery Timeline And Home Care
Mild cases improve within 4–12 hours. Eating can lag until the tongue feels better. Offer soft, smelly food in small portions—think warmed wet food or broth-soaked kibble. Keep water bowls at two or three spots. A wide, shallow dish makes it easier for a sore mouth.
Skip milk. It doesn’t bind these crystals. Don’t force food or water. If your cat won’t drink by the 6–8 hour mark or keeps vomiting, call again. Watch for lip swelling, noisy breath, or a head-low posture. Most cats return to normal in a day or two once pain calms.
Preventive House Rules That Work
- Place aglaonema in rooms the cat can’t reach, or behind a closed door.
- Use high shelves, plant cabinets, or hanging planters with sturdy hooks.
- Offer cat grass or wheatgrass as a safe chew outlet near favorite nap spots.
- Rotate enrichment: window perches, wand play, puzzle feeders, scent trails.
- Try a motion-air burst near plant stands; set it to a low pulse and test space.
- Use a bitter leaf spray made for plants; patch-test a corner leaf first.
- Keep plant tags with the Latin name taped under the pot for quick ID.
- Teach “leave it” with tiny treats; reward nose-turns away from leaves.
Safe Plant Alternatives With A Similar Look
You can keep a lush room without putting your cat at risk. Pick non-toxic choices with pattern or shine. Spider plant has playful arching leaves and lands on the safe list; see the ASPCA spider plant listing. Mix textures and pot heights to build the same layered vibe you get from aglaonema.
Safe Houseplant Swaps
| Safer Plant | Cat-Safe Status | Care Notes |
|---|---|---|
| Spider Plant (Chlorophytum) | Non-toxic to cats | Bright, indirect light; easy watering rhythm |
| Boston Fern (Nephrolepis) | Non-toxic to cats | Likes humidity; keep soil lightly moist |
| Areca Palm (Dypsis) | Non-toxic to cats | Bright room; allow top inch to dry |
| Ponytail Palm (Beaucarnea) | Non-toxic to cats | Needs bright light; sparse watering |
| Calathea / Goeppertia | Non-toxic to cats | Indirect light; steady moisture and warmth |
| Prayer Plant (Maranta) | Non-toxic to cats | Medium light; likes humidity |
| Peperomia Mix | Non-toxic to cats | Bright, indirect light; light watering |
| Hoya (Wax Plant) | Non-toxic to cats | Bright light; let soil dry between sips |
| Burro’s Tail (Sedum morganianum) | Non-toxic to cats | Bright window; lean soil; gentle handling |
| African Violet (Saintpaulia) | Non-toxic to cats | Soft light; water from below if possible |
Non-toxic doesn’t mean snack food. Cats can still gag on leaves or dirt. Keep pots steady, soil topped with stones if your cat digs, and safe chews nearby.
Myths That Cause Trouble
- “A tiny bite can’t hurt.” A quick nibble can spike mouth pain and drool.
- “Cats avoid bad plants.” Many chew from play, stress, or boredom.
- “Milk fixes plant burns.” It doesn’t neutralize these crystals.
- “Only leaves matter.” Stems carry sap too and can sting more.
- “Vomiting clears the problem.” Mouth pain can still need meds.
Caregiver Checklist For Plant Safety
- Identify every plant by Latin name; tape tags under pots.
- Store aglaonema where the cat can’t reach or swap it out.
- Add cat grass and daily play to cut plant-chewing urges.
- Stage water bowls in two rooms; refresh twice a day.
- Keep a 10–20 mL syringe and sterile saline in a drawer.
- Save your clinic’s number and a taxi option in your phone.
- Photograph any chewed leaves before cleanup.
- Log time, signs, and any home steps in a note app.

Frequently Asked Questions
How Much Aglaonema Is Dangerous For A Cat?
Even a bite can cause sharp mouth pain and drool. Larger chews raise the odds of vomiting and short-term refusal to eat. Kittens and small cats react faster since a little sap goes a long way.
If your cat won’t swallow saliva or keeps retching, call your clinic for same-day care.
What Can I Safely Do At Home Right Away?
Move the plant, offer a small drink, then rinse the mouth with lukewarm water using a syringe along the cheek. If sap reached the eye, flush with sterile saline for several minutes.
Skip milk, oils, or home remedies. Those don’t bind the crystals and can upset the stomach.
Could Mouth Burns Turn Into A Blocked Airway?
Most cats only have local pain and drool. Airway trouble is uncommon, yet any noisy breath, open-mouth breathing, or face puffiness is an emergency. Keep your cat calm and go in.
Bring a plant photo or the leaf. That speeds treatment choices at triage.
How Do I Keep Plants Without Tempting My Cat?
Use doors, tall shelves, hanging planters, or a glass cabinet. Provide cat grass and daily play to drain chewing urges. A motion-air burst near a plant stand teaches distance.
Finish with safe swaps like spider plant or calathea to build a lush, cat-friendly corner.
Will My Cat Need Blood Tests Or An IV?
Not always. These plants act locally, so labs can be normal. Vets add bloodwork if signs don’t fit or if another issue might be hiding. Fluids help if dehydration sets in from vomiting.
Most patients go home the same day once drooling slows and appetite perks up.
Wrapping It Up – Are Aglaonema Plants Toxic To Cats?
Yes, they are. The plant’s crystals jab the mouth, spark drool, and can lead to vomiting. Quick rinsing, calm handling, and a call to your clinic steer most cases toward a smooth finish. Keep the look you love with non-toxic swaps, and stage safe chews so leaves lose their appeal. If anyone in the house asks again—are aglaonema plants toxic to cats? The answer is still yes, and now you’ve got a plan.
