Is Taro Toxic to Cats?
Also known as: Elephant Ears, Dasheen, Coco Yam · Colocasia esculenta
What makes it toxic
Insoluble calcium oxalate crystals (raphides) packed through the leaves, stems and corm. When tissue is chewed, the needles pierce the lining of the mouth, tongue and throat, causing immediate burning pain and swelling.
Warning signs to watch for
Instant burning and drooling, pawing at the mouth, vomiting, reluctance to swallow and, in stronger reactions, visible swelling around the mouth.
What to do if your cat eats it
Rinse the mouth with water and remove any plant material, then offer milk or water to flush the crystals. Call your vet if drooling and vomiting persist beyond an hour or if breathing looks affected.
Common questions
Is cooked taro safe for cats?
Cooked taro root is a staple human food in much of the world because heat destroys the crystals, but raw plant tissue — the form cats meet in the house or garden — is what causes the injury.
Are all elephant ear plants taro?
The name elephant ears covers Colocasia, Alocasia and Xanthosoma — all of them contain the same calcium oxalate crystals, so all should be treated as unsafe for chewing pets.
