Verified against ASPCA/provenance audit 2026-05-06 on May 6, 2026.
Signs to watch for
Oral irritation, intense burning and irritation of mouth, tongue and lips, excessive drooling, vomiting, and difficulty swallowing.
Escalation note
The insoluble calcium oxalate crystals cause immediate mechanical irritation upon contact. If your cat has ingested any part of this plant, please contact your veterinarian or a pet poison control center.
What to watch for
Most common: pawing at the mouth, intense drooling, oral pain, vomiting, and difficulty swallowing. Rare but serious: swelling around the upper airway making breathing difficult.
Time window
Oral irritation is essentially immediate after the cat bites the plant; gastrointestinal signs usually appear within minutes to an hour.
When to call the vet
Call your vet or Pet Poison Helpline (855-764-7661) for persistent drooling, mouth or face swelling, refusal to eat, or any difficulty breathing or swallowing — call immediately for breathing trouble.
What this means for your cat
Cats that bite Octopus Tree leaves quickly run into the plant's insoluble calcium oxalate crystals, which cause a sudden, painful burning of the mouth and throat. Most cats stop chewing fast enough that signs stay localized to the mouth and stomach, but airway swelling is a rare possibility.
