Yes, devil’s ivy is poisonous to cats. The ASPCA classifies it as toxic to cats, dogs, and horses. The good news: while it causes real pain and distress, it rarely leads to life-threatening complications. Most cats recover fully with appropriate care.
Why Devil’s Ivy Is Toxic
Devil’s ivy (also called golden pothos or Epipremnum aureum) contains tiny, needle-shaped crystals called insoluble calcium oxalates packed inside its leaves and stems. When a cat bites into the plant, these microscopic crystals shoot out and physically pierce the soft tissues of the mouth, tongue, and throat. Think of them as thousands of invisible splinters embedding into delicate tissue all at once.
This is a mechanical injury, not a chemical one. The crystals don’t need to be digested or absorbed into the bloodstream to cause harm. The damage starts the moment a cat chews. That immediate, intense pain is actually somewhat protective: most cats stop eating the plant quickly, which limits how much they ingest.
Symptoms to Watch For
Signs of pothos poisoning tend to appear quickly, often within minutes of chewing. The most common symptoms include:
- Pawing at the mouth, a telltale sign of oral pain
- Excessive drooling
- Swelling of the mouth, tongue, and lips
- Vomiting
- Difficulty swallowing
- Refusing food
Some cats will also hide or become withdrawn, which is a typical feline response to pain. In more significant exposures, swelling in the mouth and throat can make breathing harder, though this is uncommon precisely because the immediate burning sensation discourages cats from eating large amounts.
What to Do If Your Cat Eats It
Start by removing any plant material from your cat’s mouth if you can do so safely. Rinse the mouth gently with water to help flush out crystals still sitting on the tissue surface. Don’t try to induce vomiting unless a veterinarian specifically tells you to.
If your cat is drooling heavily but otherwise alert and breathing normally, call your vet or the ASPCA Animal Poison Control Center (888-426-4435) for guidance. Mild cases with minimal ingestion often resolve on their own within a few hours as the irritation subsides. If you notice any swelling around the face or throat, difficulty breathing, or your cat refuses to eat or drink for more than several hours, get to a veterinarian promptly. The biggest concern with more serious cases is swelling that could restrict the airway, along with dehydration from an inability to swallow comfortably.
Veterinary treatment is mostly supportive: managing pain, reducing inflammation, and ensuring your cat stays hydrated until the irritation heals. Most cats bounce back within 24 to 48 hours.
Keeping Your Cat Safe Around Plants
Devil’s ivy is one of the most popular houseplants in the world, and its long trailing vines can be irresistible to playful cats. Simply placing the pot on a high shelf isn’t always enough since determined cats can climb or bat at dangling vines. A few strategies that actually work:
Hang the plant from the ceiling in a spot with no nearby furniture a cat could use as a launchpad. Keep vines trimmed short so they don’t dangle within reach. Move toxic plants into a room your cat doesn’t have access to, or use a closed terrarium or glass cabinet. Some owners use mesh fencing or cat gates around plant areas, though many cats can jump right over a standard gate.
If your cat is a chronic plant chewer, the safest move is replacing devil’s ivy entirely. Several vining plants look similar and are completely nontoxic to cats. Swedish ivy is a popular choice with a similar trailing growth habit and is recommended by the Pet Poison Helpline as pet-safe. Lipstick plant is another trailing option that adds color with its bright red flowers and poses no risk to cats. Spider plants and Boston ferns also work well as hanging alternatives that won’t cause harm if nibbled.
Providing cat grass or catnip plants gives your cat a safe outlet for the chewing instinct that draws them to houseplants in the first place. Cats often gravitate toward greenery because they enjoy the texture, and offering an approved option can redirect that behavior away from anything toxic.
