Pet ingestion lookup
My cat ate Elephant-Ear Begonia - what should I do?
Begonia scharfii
Potentially toxic
Contact your veterinarian or an animal poison-control resource now, especially if any amount was chewed or swallowed.
Verified against ASPCA/provenance audit 2026-05-06 on May 6, 2026.
Signs to watch for
Oral irritation, excessive drooling, difficulty swallowing, and vomiting.
Escalation note
The plant contains soluble calcium oxalates that cause immediate irritation to the mouth and throat. If your cat has ingested this plant, please contact your veterinarian for guidance.
What to watch for
Drooling and lip-licking. Vomiting. Reduced appetite. Symptoms tend to be mild when only leaves were chewed; ingestion of root or tuber material may be more pronounced.
Time window
Salivation and vomiting typically appear within a few hours of ingestion; most cats recover within 24 hours. Exact onset and duration are not well documented in the ASPCA listing.
When to call the vet
Call your vet or ASPCA Poison Control at (888) 426-4435 if vomiting is repeated, lasts more than a few hours, or your cat seems lethargic. Any suspicion that your cat dug up and chewed the tuber warrants a same-day call.
What this means for your cat
Begonias are mostly a problem for cats when they chew the leaves, but the toxic principle (soluble calcium oxalates) is concentrated in the underground tubers — so a cat digging in the pot is more concerning than one batting at a leaf. Most exposures cause mild drooling and stomach upset; the serious systemic effects ASPCA notes (kidney failure) are reported in grazing animals, not house cats. Still, watch for vomiting and call if it persists.
