My cat ate Mapleleaf Begonia - what should I do?
Begonia cleopatra
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 which cause immediate irritation to the mouth and throat. If your cat has ingested a significant amount, please contact your veterinarian.
First aid at home
Gently rinse your cat's mouth with cool water using a syringe or small cup — aim at the inner cheeks, not the back of the throat, to flush loose crystals without causing aspiration. Wipe away any plant fragments and offer fresh water (not milk).
What to watch for
Immediate pawing at the mouth, drooling, and head shaking from oral pain. Foamy vomiting, difficulty swallowing, and a few hours of reduced appetite are common. Severe swelling of the tongue or throat is uncommon but possible — that's the red-flag sign.
Time window
Signs typically appear within 5 to 15 minutes of biting the plant. Most cats recover fully within 24 to 48 hours with supportive care; prognosis is excellent when symptoms are addressed within four hours of ingestion.
When to call the vet
Call your vet or ASPCA APCC (1-888-426-4435) for any ingestion, especially in kittens or cats with breathing changes. Go in immediately if you see swelling around the face or throat, persistent drooling beyond an hour or two, or any difficulty breathing.
What this means for your cat
Mapleleaf begonia, like all begonias, is toxic to cats. The leaves and stems carry insoluble calcium oxalate crystals — microscopic needles that bury into the mouth and throat the moment your cat bites. Most ingestions are painful but not life-threatening, and the burning sensation usually stops cats from eating much.
