Many common plants, including pothos, lilies, and snake plants, are toxic to cats and can cause irritation, vomiting, or severe poisoning. This guide identifies the most dangerous houseplants, garden plants, and flowers, explains symptoms of plant toxicity, and outlines emergency steps to take if a cat ingests a harmful plant. Learn how to prevent poisoning by choosing pet-safe alternatives like cat grass and Boston ferns to create a cat-friendly home environment.
Pothos plants, also known as Devil’s Ivy (Epipremnum aureum), are a popular houseplant due to their low-maintenance care and attractive trailing vines. However, many cat owners are unaware that pothos are toxic to cats and can cause serious irritation if ingested.
If a cat chews on pothos leaves, it may experience drooling, pawing at the mouth, vomiting, or difficulty swallowing. While pothos poisoning is rarely fatal, it can cause severe discomfort and requires prompt intervention. Understanding why pothos are toxic, what symptoms to watch for, and how to keep cats safe is essential for responsible pet ownership.
According to the ASPCA Animal Poison Control Center, pothos plants account for 3.2% of all plant-related toxicity cases in cats each year. If you suspect your cat has been exposed to pothos, knowing how to respond can make all the difference.
Yes, pothos plants are toxic to cats, They contain insoluble calcium oxalate crystals, which cause intense irritation when chewed or ingested. These microscopic crystals act like tiny needles, embedding themselves in a cat’s mouth, tongue, and throat, leading to pain, swelling, and excessive drooling.
While pothos toxicity is not usually life-threatening, it can cause severe discomfort and secondary complications if left untreated. Cats that ingest large amounts may experience swelling of the throat, difficulty breathing, and vomiting.
Golden pothos (Epipremnum aureum) is one of the most common pothos varieties found in homes. While its vibrant green and yellow marbled leaves make it a popular choice for plant lovers, many pet owners wonder if golden pothos is safer than other types. The answer is no—golden pothos is just as toxic to cats as other pothos varieties.
All pothos varieties, including marble queen pothos, neon pothos, and jade pothos, contain the same toxic compounds. Golden pothos is not more toxic than other pothos plants, but its toxicity level remains the same across all Epipremnum aureum species.
Regardless of the variety, all pothos plants pose a risk to cats. This includes:
Pothos Variety | Toxic to Cats? |
Golden Pothos (Epipremnum aureum) | ✅ Yes |
Neon Pothos | ✅ Yes |
Marble Queen Pothos | ✅ Yes |
Jade Pothos | ✅ Yes |
Pearls and Jade Pothos | ✅ Yes |
Even if a cat only licks or chews on a pothos leaf, the calcium oxalate crystals can cause immediate irritation.

The toxicity of pothos plants comes from their high concentration of insoluble calcium oxalate crystals. These needle-like crystals are not digestible, meaning they cause mechanical irritation rather than chemical poisoning.
When a cat chews on pothos, the sharp raphides (needle-shaped crystals) embed into the soft tissues of the mouth, throat, and gastrointestinal tract, triggering pain, swelling, and inflammation. Unlike some toxic plants that affect internal organs, pothos primarily cause local irritation but can still be distressing for a cat.
Affected Area | Symptoms |
Mouth & Tongue | Drooling, pawing at mouth, difficulty swallowing |
Throat & Esophagus | Swelling, gagging, choking, difficulty breathing (in severe cases) |
Stomach & Intestines | Vomiting, diarrhea, loss of appetite |
Severity depends on the amount ingested. While some cats may only experience mild irritation, others could require immediate veterinary intervention.
Recognizing symptoms early is critical. The effects of pothos ingestion can appear within minutes to hours after exposure.
In rare but severe cases, throat swelling could lead to breathing difficulties, requiring urgent veterinary care.
If a cat chews on a pothos plant, symptoms may appear within minutes to a few hours. The severity depends on how much was ingested. Immediate action can help reduce discomfort and prevent complications.
Check your cat’s mouth and gently remove any remaining leaves or stems. Avoid using your fingers if the cat is in distress—flushing the mouth with water may be safer.
Use a clean, damp cloth or a pet-safe saline rinse to wipe the inside of the mouth. This helps remove calcium oxalate crystals that cause irritation. Offer small sips of water to soothe discomfort.
Observe your cat for drooling, pawing at the mouth, vomiting, or swelling. If symptoms are mild, they may resolve within a few hours. If there is persistent discomfort, difficulty breathing, or severe vomiting, seek veterinary care immediately.
Unlike some toxins, pothos affects the mouth and throat more than the stomach. Inducing vomiting can worsen irritation and is not recommended unless directed by a veterinarian.
Some cases require professional treatment. Seek veterinary care if your cat:
A veterinarian may provide:
Fact Check: The Pet Poison Helpline reports that around 15% of pothos toxicity cases in cats require veterinary treatment beyond home care (source).
Keeping pothos plants away from pets is the best way to prevent poisoning. Some cats are more curious than others, so extra precautions may be necessary.
Prevention Method | Effectiveness |
Placing plants out of reach (high shelves, hanging baskets) | ✅ Highly effective |
Using bitter-tasting deterrent sprays | ✅ Moderately effective |
Providing safe plant alternatives | ✅ Effective if cat prefers safe options |
Covering soil with smooth stones to deter digging | ✅ Prevents chewing from the base |
If a cat continues to chew on plants, redirecting its attention to safer options can help.
Many popular indoor plants contain toxic compounds that can cause vomiting, diarrhea, difficulty breathing, or organ damage in cats.
Plant Name | Toxic Compounds | Effects on Cats |
Pothos (Epipremnum aureum) | Calcium oxalate crystals | Oral irritation, drooling, vomiting |
Snake Plant (Sansevieria trifasciata) | Saponins | Nausea, vomiting, diarrhea |
Dieffenbachia (Dumb Cane) | Calcium oxalate crystals | Mouth pain, swelling, difficulty swallowing |
Aloe Vera | Saponins & anthraquinones | Vomiting, diarrhea, lethargy |
ZZ Plant (Zamioculcas zamiifolia) | Calcium oxalate crystals | Oral irritation, vomiting |
Peace Lily (Spathiphyllum) | Calcium oxalate crystals | Drooling, oral irritation, vomiting |
Philodendron | Calcium oxalate crystals | Swelling, vomiting, difficulty swallowing |
Monstera (Swiss Cheese Plant) | Calcium oxalate crystals | Oral irritation, drooling, vomiting |
Many of these plants are commonly kept indoors due to their low maintenance, but they should be placed out of reach or replaced with pet-safe alternatives.
Instead of pothos, consider pet-friendly plants that allow cats to safely satisfy their chewing instincts.
Cat-Safe Plant | Benefits |
Cat Grass (Dactylis glomerata) | Safe to chew, aids digestion |
Catnip (Nepeta cataria) | Provides mental stimulation |
Areca Palm (Dypsis lutescens) | Non-toxic decorative plant |
Boston Fern (Nephrolepis exaltata) | Safe and visually appealing |
Creating a designated cat-friendly plant area can help keep cats away from toxic plants while satisfying their curiosity.
Mild cases, where a cat only chews on a leaf, may resolve within a few hours. More severe reactions, such as vomiting or throat irritation, can last 12 to 24 hours. If a cat ingests a larger amount or has difficulty swallowing, symptoms may persist for several days, requiring veterinary care.
Severity | Expected Duration | Treatment Needed? |
Mild (drooling, mild irritation) | 1-4 hours | No, monitor at home |
Moderate (vomiting, swelling) | 12-24 hours | Possibly, consult a vet |
Severe (difficulty breathing, extreme pain) | 24+ hours | Yes, urgent vet care |
If a cat’s symptoms do not improve within 24 hours, a veterinarian should assess the situation.
Fatal cases are extremely rare, but severe reactions can lead to swelling in the throat, excessive vomiting, or dehydration, which can become life-threatening if left untreated. Most cats recover fully with prompt care.
Fact Check: The ASPCA states that while pothos toxicity causes discomfort, it is not classified as fatal unless complications arise.
If a cat appears completely normal after ingestion, it may have only had a small nibble. However, it is still advisable to:
Even if a cat shows no immediate symptoms, effects can sometimes appear a few hours later. Keeping an eye on behavior for the next 24 hours is the safest approach.
