When we take our pets outside, it’s easy to forget the dangers lurking in plain sight. One such threat is the Elephant Ear plant, Xanthosoma also known as the taro.1 It has large leaves that look like elephant ears. People often grow it in their gardens for the dramatic appearance of its huge red, green, or blue leaves. Elephant Ear is poisonous to mammals, including cats.2

In this article, we will cover everything you need to know about Elephant Ear poisoning, the causes, symptoms, treatment, and recovery. Afterward, you will be well prepared to not only keep your kitty safe but know what to do if they get sick.

What Is Elephant Ear Poisoning?

Elephant’s Ear is a name for several different genera of plants Alocasia, Caladium, Colocasia, and Xanthosoma amongst them. They all contain insoluble sharp raphide crystals called calcium oxalate that pierce the mouth and throat tissues when eaten. The airways can swell, and there may be additional allergic reactions too. Brushing up against an Elephant Ear plant can also irritate the skin and cause blisters.

Poisoning by Xanthosoma isn’t very common as the plant is bitter, but it is highly irritant so it’s important to know how to prevent and treat it.

What Are The Causes of Elephant Ear Poisoning?

Because of its impressive size and appearance, the Elephant Ear plant has become very popular with landscapers across the country. This poses a serious risk for outdoor cats and is something to be aware of if you let your cat outdoors for any reason.

Fortunately, cats don’t usually eat a lot of the plant due to the immediate irritation and burning in their mouths once they chew it. The sharp raphides are concentrated in the stems and leaves.

How To Diagnose Elephant Ear Poisoning

In the case that your cat does eat a large amount of elephant ear, treat it like a medical emergency and immediately take them to the vet. Be sure to have your pet’s medical history available, so the vet can diagnose them properly and not assume it’s a pre-existing condition. If possible, bring a piece of the plant that your cat ate with you to help the doctor make an accurate diagnosis.

Your cat will receive a thorough examination and will get immediate treatment to stabilize their vitals if necessary. Blood tests will be run as well as a urinalysis to check the condition of the kidneys. The heart and lungs will also be checked.

How To Treat Elephant Ear Poisoning

Although there is no antidote for Elephant Ear poisoning, the most successful treatment focuses on the symptoms and keeping your cat comfortable.

  • Flush Exposed Areas: For contact with the eyes or mouth, flush the areas with water immediately to help cool the burning and irritation and remove the raphides. Can offer a small amount of milk or yogurt to help bind the oxalate crystals.
  • Supportive Care: After suffering from gastrointestinal problems, your cat can become dehydrated, so an IV may be necessary to replace critical fluids. It’s important to monitor their breathing and organ function during this time.
  • Medications: Your vet may need to give medications for pain relief, to stop vomiting, reduce throat swelling and protect the gastro-intestinal tract.

Recovery From Elephant Ear Poisoning

The most serious symptoms of Elephant Ear poisoning usually manifest and pass within the first 24 hours. However, sickness can last for up to two weeks. The severity of your cat’s condition will depend on how much of the plant they ate, how the cat was affected and any resulting kidney damage.

To prevent poisoning, many cat owners choose to not have Elephant Ear plants at all or to put them out of reach of their pets. Other people just keep their cats indoors to avoid the risk altogether.

Conclusion

As we have seen, the Elephant Ear is a highly toxic plant that can cause your cat harm and distress. If you think your cat may have been poisoned, take them to the vet for an immediate exam and diagnosis after flushing any exposed areas.

Your vet will diagnose and treat them as needed, and the worst should pass within the first day.

Fortunately, cat deaths from Elephant Ear poisoning are rare and can be avoided with preventative measures. You can keep your pet inside and make sure there are no such plants on your property. If you take your cat for walks, the Elephant Ear is recognizable, so you can easily give it a wide berth.
