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.

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.

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).
