My cat ate Hyacinth - what should I do?
Hyacinthus orientalis
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
Intense burning and irritation of the mouth, tongue, and lips, excessive drooling, vomiting, and difficulty swallowing.
Escalation note
The bulbs are the most toxic part of the plant. If your cat has ingested any portion of this plant, please contact your veterinarian or a pet poison control center immediately.
First aid at home
Rinse your cat's mouth gently with lukewarm water if she will tolerate it, and remove any remaining plant material from the area. Do NOT try to make your cat vomit at home — there is no safe over-the-counter way to induce vomiting in cats, and it can cause more harm than the plant. Call your vet or Pet Poison Helpline (855-764-7661) before giving anything by mouth.
What to watch for
Most common in cats: profuse drooling, retching, and vomiting (sometimes with blood after a bulb chew), followed by diarrhea and depression. Watch for tremors, weakness, or changes in breathing — those are signs of a larger ingestion and need immediate veterinary attention.
Time window
Onset is typically within 1–2 hours of ingestion (often sooner with bulbs, because the irritant crystals act on contact). With supportive care — anti-nausea medication, fluids, mouth rinsing — most cats recover within 24–48 hours. Bulb ingestions can take longer.
When to call the vet
Call immediately if your cat chewed or ingested any part of a bulb — that's the high-risk exposure. For exposure to leaves or petals, call if drooling, vomiting, or lethargy lasts more than a few hours, or any time you see tremors, blood in vomit, or labored breathing. Pet Poison Helpline (855-764-7661) and your veterinarian can advise on whether to come in.
What this means for your cat
Cats that bite into a hyacinth bulb get the worst of this plant — bulbs hold the highest concentration of narcissus-like alkaloids and irritant crystals, and one chewed bulb can put a cat into intense vomiting and tremors. Foliage and flowers are toxic too, but mostly cause drooling and stomach upset.
