Safety status
What this means for your cat
Cats that chew schefflera get an immediate burning mouthful of needle-like calcium oxalate crystals. The pain comes on within seconds, which usually deters more eating, but a curious cat can still get a nasty oral injury. Most cases respond to home care plus a vet check, but airway swelling is the rare outcome to rule out.
What to watch for
Sudden drooling and pawing at the face are the giveaways, often with head shaking and lip-smacking. Vomiting and refusal to eat usually follow. The serious-but-rare signs are visible swelling of the lips, tongue, or throat and any change in how your cat is breathing.
Time window
Onset is within seconds. Most cats are visibly improved within a few hours and back to normal within 24–48 hours with supportive care.
When to call the vet
Call immediately for any swelling around the mouth or throat, noisy or labored breathing, or repeated vomiting. Even with mild signs, a same-day call is right — cats can hide oral pain and stop drinking, which leads to dehydration.
First aid at home
Wipe out the mouth with a damp cloth to remove any remaining plant material, then offer a small amount of milk or yogurt — the calcium helps bind the oxalate crystals and ease the burn. Rinse paws and fur if your cat had contact. Do not induce vomiting. Call your vet or Pet Poison Helpline next.
