My cat ate Elephant Ears - what should I do?
Colocasia esculenta
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, intense burning and irritation of the mouth, tongue and lips, excessive drooling, vomiting, and difficulty swallowing.
Escalation note
The presence of insoluble calcium oxalate crystals causes immediate mechanical irritation. If your cat has ingested this plant, please contact your veterinarian or a pet poison control center immediately.
First aid at home
Remove plant material from your cat's mouth. A small amount of xylitol-free milk, yogurt, or vanilla ice cream can soothe oral irritation (ASPCA guidance for insoluble-oxalate plants). Don't induce vomiting at home. Call ASPCA Poison Control at (888) 426-4435 or your veterinarian.
What to watch for
Foamy drooling and head-shaking. Pawing at the mouth. Vocalizing, refusing food, or hiding. Vomiting (less common in cats than dogs, but possible). Rare but serious: swelling of the tongue or upper airway that affects breathing.
Time window
Mouth symptoms usually appear within minutes of chewing. Most cats are back to normal within 12–24 hours; rare airway swelling can develop later in the first few hours, so don't dismiss a 'better' cat too early.
When to call the vet
Call your vet or ASPCA Poison Control at (888) 426-4435 immediately. Treat any swelling, breathing difficulty, or non-stop retching as a true emergency and head to the ER.
What this means for your cat
Cats that bite into elephant ears immediately encounter insoluble calcium oxalate crystals — the same family of irritant found in dieffenbachia and philodendron. The reaction is sharp and fast, and most cats spit the plant out before swallowing much. Even so, the oral pain and drooling that follow are real, and rare upper-airway swelling makes any chewing worth a call.
