Pothos (Epipremnum aureum) is one of the most popular houseplants in the world. It is cheap, nearly impossible to kill, and available in every garden centre and hardware store. It is also genuinely toxic to cats, and if you have both a cat and a pothos plant, one of them needs to go.
This guide covers exactly what pothos does to cats, how serious it is, what symptoms to watch for, and — most importantly — the best safe alternatives that give you the same aesthetic without the risk.
Yes, Pothos Is Toxic to Cats
Pothos is listed as toxic to cats on the ASPCA Animal Poison Control database. The plant contains insoluble calcium oxalate crystals — microscopic, needle-shaped structures packed into specialised cells throughout the plant's tissue. When a cat bites or chews any part of a pothos plant, these cells rupture and fire the crystals into the soft tissue of the mouth, tongue, and throat.
The crystals do not dissolve. They physically embed in the tissue and cause intense burning and irritation within seconds of contact. This is the mechanism behind most of the symptoms you will see.
What Pothos Does to Cats: Symptoms in Detail
The reaction is usually immediate and obvious. Within seconds of chewing:
- Intense oral burning sensation
- Excessive drooling — often dramatic
- Pawing at the mouth and face
- Vomiting
- Difficulty swallowing
- Reluctance to eat or drink
In most cases, the intensity of the immediate burning sensation stops cats from eating large amounts. The pain kicks in before they can consume enough to cause serious harm. However, some persistent cats will continue chewing despite the discomfort, and repeated exposure over time can cause chronic oral irritation and gastrointestinal issues.
In larger ingestions, swelling of the mouth, tongue, and throat is possible. Any sign of throat swelling or breathing difficulty is a veterinary emergency.
Is Pothos Fatal to Cats?
Pothos is not fatal in the way that true lilies are. It does not cause kidney failure. The vast majority of pothos ingestion cases resolve within a few hours without lasting harm. However:
- The distress it causes is real and significant
- Throat swelling, while uncommon, can be dangerous
- Repeated low-level exposure causes cumulative oral and gastrointestinal damage
- Some cats are more sensitive than others
The conclusion is still clear: pothos should not be in a household with cats. Not on a high shelf (cats can reach almost anywhere), not in a hanging basket (they will learn to jump for it), not anywhere in the home.
All Pothos Varieties Are Equally Toxic
One of the most common questions: is golden pothos safer than marble queen? Is neon pothos less toxic than standard green?
No. All pothos varieties — golden, marble queen, neon, pearl and jade, global green, satin (though technically Scindapsus), and all other cultivars — are the same species (Epipremnum aureum) and contain the same concentration of calcium oxalate crystals. No variety is safer than another. The toxicity is in the plant's tissue regardless of leaf colouration or variegation.
The Full Toxic Family: Plants Related to Pothos
Pothos is one of several popular houseplants that share the same calcium oxalate mechanism. If you are removing pothos, also check your home for:
- Philodendron (heartleaf, Brasil, velvet-leaf, split-leaf) — same mechanism, same toxicity
- Monstera (deliciosa, adansonii) — the Swiss cheese plant, also toxic
- Scindapsus (pictus, treubii) — sold as “satin pothos” or “silver pothos”, equally toxic
- Peace Lily (Spathiphyllum) — same family, same toxicity class
- Dieffenbachia (Dumb Cane) — very high oxalate content, can cause severe swelling
- Caladium — high calcium oxalate content, toxic to cats
All of the above should be removed from cat households.
What to Do If Your Cat Eats Pothos
If you have seen your cat chew on pothos or suspect they have:
- Remain calm — this is not usually a life-threatening emergency
- Rinse your cat's mouth gently with water if they will allow it — this can help dislodge crystals
- Call your vet or the ASPCA Animal Poison Control Center: 888-426-4435
- Watch for drooling, vomiting, pawing at the face — these are expected
- Go to the vet if symptoms are severe, persist beyond 2 hours, or if you see any throat swelling
Do not induce vomiting unless specifically instructed to by a veterinarian.
The Best Safe Alternatives to Pothos
The good news: there are several cat-safe plants that fill exactly the same role as pothos — trailing or climbing, low-light tolerant, beginner-friendly, low-maintenance. Here are the best replacements by use case.
For Hanging Baskets and Trailing Displays
- Swedish Ivy (Plectranthus australis) — the closest like-for-like replacement. Fast-growing, glossy, scalloped leaves that trail identically to pothos. Non-toxic. Will look nearly identical in a hanging basket.
- String of Turtles (Peperomia rotundifolia) — slower but visually distinctive, with tiny patterned leaves. Non-toxic and charming.
For Low-Light Shelves
- Prayer Plant (Maranta leuconeura) — striking patterned leaves, tolerates low to medium indirect light, completely non-toxic. Moves with the light throughout the day.
- Cast Iron Plant (Aspidistra elatior) — indestructible in low light, non-toxic, architectural. Nothing kills it.
For Glossy Green Leaves
- Baby Rubber Plant (Peperomia obtusifolia) — thick, dark, glossy leaves that look similar to jade pothos. Non-toxic and drought-tolerant.
- Wax Plant / Hoya (Hoya carnosa) — slow-growing but eventually rewarding with fragrant waxy star-shaped flower clusters. Non-toxic.
For Fast Growth and Propagation
- Spider Plant (Chlorophytum comosum) — produces runners constantly, tolerates almost any condition, non-toxic. Cats are attracted to it but it is safe.
Frequently Asked Questions
What happens if a cat eats a small amount of pothos?
Expect immediate oral burning, excessive drooling, and likely vomiting. Most cats stop eating quickly because of the pain. Call your vet if symptoms persist beyond 2 hours or if your cat stops eating entirely. Most small ingestions resolve within a few hours without treatment.
Is pothos toxic to cats if they just smell it?
No. The toxin requires chewing or ingesting plant material to cause harm. Simply being near a pothos plant or sniffing it does not cause toxicity. The risk is from direct ingestion only.
Can I keep pothos in my home if I put it somewhere my cat can't reach?
This is not reliable. Cats are exceptional climbers and jumpers. A plant placed somewhere “out of reach” is a plant your cat has not yet reached. The only safe approach is to rehome the pothos or replace it with a non-toxic alternative.
How long after eating pothos do symptoms start?
Almost immediately — usually within seconds to minutes of contact. The calcium oxalate crystals cause burning as soon as they contact tissue. If your cat has eaten pothos and you are not seeing symptoms, they likely ate a very small amount. Still worth calling your vet to confirm the situation is low-risk.
