Are Pothos Toxic to Cats?
Last Updated: April 2026 · Pet Safety Guide
Direct Answer
Yes, pothos are toxic to cats (and dogs). All parts of the plant contain insoluble calcium oxalate crystals that cause immediate oral pain, swelling, drooling, and difficulty swallowing if chewed or ingested. While rarely fatal, pothos ingestion requires veterinary attention if symptoms are severe.
Why Pothos Irritates Cats
Pothos, also sold as devil's ivy or golden pothos, contains insoluble calcium oxalate crystals. These are microscopic, needle-like crystals stored in the plant tissue. When a cat bites a leaf or stem, the crystals can irritate the lips, tongue, mouth, and throat almost immediately.
This is different from a toxin that quietly damages an internal organ over time. Pothos usually causes fast, painful mouth irritation, which is why many cats spit it out quickly. That does not make it safe: swelling, vomiting, and difficulty swallowing can still happen, especially if a cat chews more than a small nibble.
Symptoms of Pothos Ingestion
| Symptom | What It Can Mean | Urgency |
|---|---|---|
| Drooling or lip licking | Mouth irritation from crystals | Monitor closely |
| Pawing at the mouth | Pain or burning sensation | Call for advice |
| Vomiting | Plant material or irritation | Call vet if repeated |
| Swollen mouth or tongue | Stronger local reaction | Contact vet promptly |
| Trouble breathing or swallowing | Possible throat swelling | Emergency care |
What to Do
- Move the plant away so your cat cannot chew more leaves or stems.
- Remove loose plant material from the mouth if you can do so safely. Do not force your cat's mouth open if they are distressed.
- Offer water to help rinse the mouth. Do not induce vomiting unless a veterinarian specifically tells you to.
- Call your veterinarian or the ASPCA Animal Poison Control Center at 888-426-4435, especially if symptoms are more than mild drooling.

Safe Alternatives to Pothos
If you love the trailing look but have a curious cat, choose plants that give a similar cascading effect with a safer profile.
Spider Plant
Arching leaves and baby plantlets; forgiving and commonly listed as non-toxic.
Boston Fern
Soft, full fronds; needs more humidity than pothos but gives a lush trailing look.
Lipstick Plant
Trailing stems and red blooms; a strong alternative for hanging baskets.
Peperomia
Compact, varied foliage; good for shelves where a shorter plant is better.
If You Keep Pothos Anyway
Some cat owners keep pothos successfully by placing it completely out of reach, but “out of reach” has to account for climbing, jumping, and falling vines. Hanging baskets can still be risky if vines trail low enough to bat or bite.
- →Trim long vines before they hang into a cat-accessible path.
- →Use a closed plant cabinet or room your cat cannot enter.
- →Offer safer enrichment, such as cat grass, so houseplants are less interesting.
- xDo not rely on bitter sprays alone; determined cats often ignore them.
