# Is Hedera Ivy Toxic to Cats? English Ivy Poisoning Is hedera ivy toxic to cats? Yes. English ivy (Hedera helix) is toxic to cats, and eating the leaves or berries can cause vomiting, drooling, abdominal pain, and wobbliness [1]. The plant is common indoors and outdoors in the United States, so many cats live within reach of it. This article is educational and is not a substitute for veterinary diagnosis or treatment. ## Quick Answer - English ivy is toxic to cats, dogs, and horses. The toxic principles are triterpenoid saponins, mainly hederagenin [1]. - The foliage is more toxic than the berries, so a cat chewing leaves is the bigger concern [1]. - Common signs include vomiting, abdominal pain, hypersalivation (drooling), and diarrhea [1]. - Neurologic signs such as wobbliness or unsteadiness can occur, and these warrant urgent care. - If your cat ate ivy, call your veterinarian, the ASPCA Animal Poison Control Center at (888) 426-4435, or Pet Poison Helpline at (855) 764-7661. Do not induce vomiting unless a veterinarian tells you to. ## Is English Ivy Toxic to Cats? Yes. English ivy, whose scientific name is Hedera helix, is listed as toxic to cats by the ASPCA Animal Poison Control Center [1]. It is also toxic to dogs and horses [1]. The plant belongs to the Araliaceae family, and it goes by many common names, including branching ivy, glacier ivy, needlepoint ivy, sweetheart ivy, and California ivy [1]. Hahn's self branching English ivy is the same species and carries the same toxicity [2]. This matters because ivy is sold in many forms. You may find it as a hanging basket, a potted table plant, a topiary, or a ground cover in the yard. A cat does not need to eat a whole plant to get sick. Chewing a few leaves is often enough to cause signs. ### Which Parts of the Plant Are Toxic? The leaves and foliage are the most toxic part of English ivy [1]. The berries also contain the toxic principle, but they are less toxic than the foliage [1]. In practice, most cat exposures involve leaves, since cats nibble on hanging vines or low-growing plants. Any product made from the plant should also be treated as a risk. Ivy extracts appear in some human cough preparations and in feed additives for animals. A European Food Safety Authority panel reviewed a common ivy leaf extract used as a feed additive and concluded it was safe up to set levels in complete feed for several species, including cats, at 600 mg/kg [3]. That finding applies to a measured, manufactured additive in commercial feed. It does not mean a cat can safely chew on your houseplant. The dose, the plant part, and the form are completely different. ### Is Hedera Helix Cat Toxicity the Same as Other Ivies? Hedera helix is the classic English ivy, and it is the plant most people mean when they say "ivy." Other plants called ivy may belong to different species with different toxins. If you are unsure what your cat ate, bring a photo or a cutting to your veterinarian. Identification guides for cats and plants can help you sort out what is in your home. Our article on [Plants Toxic To Cats](/knowledge/veterinary-medicine/toxicology-and-food-safety/plants-toxic-to-cats) covers several common species, and [What Plants Can Be Toxic To Cats](/knowledge/veterinary-medicine/toxicology-and-food-safety/what-plants-can-be-toxic-to-cats) explains how to check a plant you cannot name. ## The Toxic Principle and What It Does in the Body The toxic principles in English ivy are triterpenoid saponins, chiefly hederagenin [1]. Saponins are soap-like compounds. When a cat chews the plant, these compounds contact the mouth, stomach, and intestinal lining. That contact irritates the digestive tract. The result is the classic cluster of signs: vomiting, abdominal pain, drooling, and diarrhea [1]. Drooling often starts first because the mouth and throat are irritated right away. Vomiting and diarrhea follow as the plant material moves through the gut. Saponins can also affect the nervous system in some cases, which is why wobbliness and unsteadiness are reported with ivy poisoning. The exact mechanism is not fully worked out in veterinary research, but the clinical picture is well recognized. If your cat seems drunk, off balance, or weak after chewing a plant, treat it as an emergency. ## Ivy Poisoning Symptoms in Cats Signs usually appear within a few hours of ingestion. Mild cases may involve one or two episodes of vomiting and some drooling. More significant cases can include repeated vomiting, painful belly, diarrhea, and neurologic signs. Watch for these signs after a known or suspected exposure: - Vomiting, sometimes repeated - Drooling or excessive salivation - Abdominal pain (your cat may guard the belly, cry, or resist being picked up) - Diarrhea - Wobbliness, unsteady walking, or a drunken gait - Loss of appetite - Lethargy or hiding ### Timeline: When Do Signs Show Up? Most cats show signs within a few hours of eating ivy. Vomiting and drooling tend to come first. Diarrhea and belly pain can follow over the next several hours. Neurologic signs, when they happen, may appear alongside the stomach signs or shortly after. Some cats eat a small amount and have mild signs that settle with supportive care. Others eat more or are more sensitive and need hospitalization. You cannot predict which way it will go from the outside, so a call to a veterinarian is the right first step. ### Cat Ate Ivy Leaves: What You May See at Home If you catch your cat in the act, save the chewed plant material if you can. Note roughly how much seems to be missing and when it happened. Take a photo of the plant. This information helps your veterinarian and the poison control team assess the exposure. If you did not see it happen, the clues are sudden vomiting, drooling, or a wobbly walk in a cat with access to ivy. Cats are good at hiding plant chewing, so a new plant in the house plus sudden stomach signs is a reasonable suspicion. ## What to Do Right Now Call for advice before you do anything else. Your options are your own veterinarian, an emergency veterinary hospital, the ASPCA Animal Poison Control Center at (888) 426-4435, or Pet Poison Helpline at (855) 764-7661. These services can tell you whether the exposure is likely to be serious based on your cat's size, the amount eaten, and the timing. Do not induce vomiting unless a veterinarian tells you to. Making a cat vomit at home can cause aspiration, where vomit enters the lungs, and it can be dangerous if the cat is already wobbly or depressed. It can also be the wrong move for some toxins. Let a veterinarian decide. Do not give human medications, milk, oil, or home remedies. Do not wait to see if signs get worse before calling. Early advice is cheaper and safer than waiting for a sick cat. If your cat is vomiting repeatedly, cannot stand, is having trouble breathing, or is unresponsive, go to an emergency hospital now. Do not spend time on the phone first if your cat looks critical. ## How Veterinarians Treat Ivy Poisoning in Cats Treatment depends on how much was eaten, how long ago it happened, and how sick your cat is. There is no antidote for English ivy saponins, so care is supportive. Your veterinarian may start with a physical exam and questions about the exposure. If ingestion was recent and your cat is stable, they may give medication to control vomiting and, in some cases, administer activated charcoal to bind plant material still in the gut. They will decide whether decontamination is safe for your cat. Most cats need fluids to correct dehydration from vomiting and diarrhea. Anti-nausea medication and stomach protectants ease the gut irritation. A bland diet may be started once vomiting is controlled. Cats with neurologic signs are monitored closely and may need hospitalization. Blood work is often recommended to check hydration, electrolytes, and organ values. This is not because ivy is known to cause liver or kidney failure, but because vomiting and poor intake can throw off a cat's internal balance, especially in kittens, seniors, and cats with other health problems. Your veterinarian calculates any medication dose from your cat's weight and health status. There is no standard home dose for this situation. ## Outlook After Ivy Ingestion The outlook is generally good with prompt care. Many cats with mild exposures recover within a day or two with supportive treatment. Cats with heavy exposures or neurologic signs may need longer hospitalization but often still recover. The risk goes up when treatment is delayed, when a cat has underlying disease, or when the exposure is large. Kittens and older cats tend to have less reserve. If your cat is in one of these groups, call sooner. If your cat has swallowed part of a plant and you are not sure what it was, our guide to [House Plants Toxic To Kittens](/knowledge/veterinary-medicine/toxicology-and-food-safety/house-plants-toxic-to-kittens) covers the plants most often involved in young cat households. ## Prevention and Safer Alternatives The simplest prevention is to keep English ivy out of your home and out of your cat's reach. If you love the look of ivy, choose a cat-safe plant instead. Good options include spider plants, Boston ferns, and most true palms. Check any plant against a reliable toxic plant list before you bring it home. If you already have ivy, you have a few choices. You can rehome it, hang it where your cat truly cannot reach it (a closed room works better than a high shelf, since cats climb), or place it behind a barrier. Outdoor ivy on fences and walls can also be chewed, so supervise outdoor time or block access. Cats chew plants for many reasons, including boredom and curiosity. Offering cat grass or a safe potted plant can redirect the behavior. Rotating toys and adding climbing space also helps. If your cat chews plants constantly, mention it at your next routine visit.

Your cat's case needs a veterinarian who can examine your cat, ask about the exposure, and decide on treatment. Contact a veterinarian the same day if your cat ate ivy and is vomiting, drooling, or has diarrhea but is otherwise bright and steady on its feet. Same-day advice also applies if you are not sure whether your cat ate the plant but the leaves look chewed. Go to an emergency hospital now if your cat is wobbly, cannot walk straight, is vomiting repeatedly and cannot keep water down, is breathing fast or hard, is collapsed, or is unresponsive. Neurologic signs after plant ingestion are an emergency. Schedule a routine visit if your cat has a habit of chewing plants, if you want help cat-proofing your home, or if your cat had a mild exposure and has recovered but you want a checkup. Bring a photo of the plant to the visit. ## Frequently Asked Questions ### Is English ivy toxic to cats? Yes, English ivy is toxic to cats. It contains triterpenoid saponins, mainly hederagenin, that irritate the digestive tract and can also cause neurologic signs. The leaves are more toxic than the berries. ### Can a cat die from eating English ivy? Death is uncommon, and most cats recover with supportive care. Serious cases are more likely with large amounts eaten, delayed treatment, or underlying health problems. Any cat with neurologic signs needs urgent veterinary care. ### How long after eating ivy will my cat get sick? Signs usually start within a few hours. Drooling and vomiting often come first, with diarrhea and belly pain following. If your cat ate ivy and looks normal several hours later, keep watching and call your veterinarian for guidance. ### Will my cat vomit on its own after eating ivy? Often yes, because the plant irritates the stomach. Do not try to make your cat vomit at home. Inducing vomiting can cause serious complications, and a veterinarian should decide whether it is safe for your cat. ### Are ivy berries toxic to cats? Yes, the berries contain the same toxic principle as the leaves, though the foliage is more toxic. A cat that eats berries should still be evaluated, especially if vomiting or drooling starts. ## Related Articles - [Are Orchids Toxic To Cats](/knowledge/veterinary-medicine/toxicology-and-food-safety/are-orchids-toxic-to-cats) - [Plants Toxic To Cats](/knowledge/veterinary-medicine/toxicology-and-food-safety/plants-toxic-to-cats) - [What Plants Can Be Toxic To Cats](/knowledge/veterinary-medicine/toxicology-and-food-safety/what-plants-can-be-toxic-to-cats) - [House Plants Toxic To Kittens](/knowledge/veterinary-medicine/toxicology-and-food-safety/house-plants-toxic-to-kittens) - [House Plants Toxic To Cat](/knowledge/veterinary-medicine/toxicology-and-food-safety/house-plants-toxic-to-cat) - [Are Lilies Toxic to Cats?](/knowledge/veterinary-medicine/toxicology-and-food-safety/are-lilies-toxic-to-cats) - [Is English Ivy Safe for Cats?
