Questions about Elephant-Ear Begonia

Is Elephant-Ear Begonia toxic to cats?

Yes, Elephant-Ear Begonia (Begonia scharfii) is toxic to cats. It contains soluble calcium oxalates that cause immediate irritation to the mouth and throat if ingested.

What symptoms will my cat show after eating Elephant-Ear Begonia?

What should I do if my cat ate an Elephant-Ear Begonia?

Remove your cat from the plant and rinse their mouth with water if possible. Contact your vet or the ASPCA Animal Poison Control Center at (888) 426-4435 if vomiting is repeated, lasts more than a few hours, or your cat seems lethargic. Any suspicion that your cat chewed the root or tuber warrants a same-day call.

Is the root of Elephant-Ear Begonia more dangerous to cats than the leaves?

What symptoms will my dog show after eating Elephant-Ear Begonia?

Expect drooling, repeated vomiting, lip-licking, and reduced appetite. Symptoms typically appear within a few hours of ingestion, and severity tends to scale with how much root or tuber material was chewed and swallowed. Most dogs return to normal within 24 hours.

What should I do if my dog ate an Elephant-Ear Begonia?

Remove any remaining plant material from your dog's mouth and offer fresh water. Call your vet or the ASPCA Animal Poison Control Center at (888) 426-4435 if vomiting won't stop, your dog refuses water, or you suspect any of the tuber was eaten.

Which part of Elephant-Ear Begonia is most dangerous to dogs?
