Why amaryllis bulbs are dangerous for pets
Amaryllis bulbs contain lycorine alkaloids that irritate the gastrointestinal tract and can affect the nervous system in larger doses.
The bulb looks like a large brown onion and is by far the most toxic part of the plant — a small cat needing only a bite-sized piece to become severely ill.
Owners often do not realise the danger because the bulb is buried in soil and only noticed after the pet has dug it up and chewed it.
The leaves and flowers are less toxic but can still cause mild stomach upset if swallowed.
A knocked-over pot with exposed soil and a broken bulb is the most common scene owners find in the morning.
Why speed matters
Delaying care significantly worsens outcomes. Some signs appear hours or days later, so "looks fine right now" is not a reason to wait.
Symptoms of amaryllis poisoning
- Repeated vomiting starting 1 to 4 hours after chewing the bulb.
- Diarrhoea developing within a few hours of ingestion.
- Heavy drooling and frequent pawing at the mouth as the pet tries to clear the irritation.
- Trembling or noticeable weakness if a large piece of bulb was eaten.
- Lethargy that persists throughout the day and does not respond to rest.
- Refusal to eat or drink for more than 12 hours after the incident.
What to do right now
- Call your vet or Pet Poison Helpline at 855-764-7661 immediately.
- Bring the plant label or a clear photo of the bulb — vets need to know which part was eaten and roughly how much.
- Check the pet gums for paleness — pale or white gums after repeated vomiting can signal early shock.
- Do not induce vomiting on your own — plant alkaloids can cause aspiration pneumonia if vomit is inhaled into the lungs.
- Wrap any remaining bulb pieces in a towel and dispose of them in a sealed outdoor bin — do not leave fragments in the house.
