What should I do if my cat ate Hyacinth?

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. 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.

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.

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.
