Pothos is one of the most-chewed houseplants in cat households because the trailing vines look like prey. The leaves are studded with insoluble calcium oxalate raphides — needle-like crystals that fire into the tongue and gums the moment a cat bites down. The reaction looks alarming (drooling, pawing, vomiting) but in most cats stays confined to the mouth and stomach and resolves within a couple of days.
First few minutes: hypersalivation, lip licking, head shaking, pawing at the muzzle, and rubbing the face on furniture or the floor. Within roughly half an hour: vomiting (often with visible leaf fragments), gagging, reluctance to eat or drink, and mild lethargy. Less common but worth watching for: visible swelling inside the mouth or any change in breathing.
Hypersalivation and pawing usually start within 0–5 minutes of chewing. Vomiting and reluctance to eat tend to follow within 5–30 minutes. With supportive care, most cats recover within 1–3 days.
Call your vet or Pet Poison Helpline (855-764-7661) any time drooling persists more than an hour, your cat won't drink water, vomiting keeps recurring, or you see swelling of the lips or tongue. Difficulty breathing or any sign of airway swelling is an emergency — head straight to a clinic.
Remove any leaf material still in your cat's mouth and gently rinse the mouth with clean, cool water to flush out remaining crystals. Do NOT induce vomiting — bringing the oxalate material back up causes additional burning to the esophagus and mouth. Then call your vet or Pet Poison Helpline.
