Are Tulips and Daffodils Toxic to Cats?
Tulips and daffodils contain toxic alkaloids (tulipalin A and lycorine) concentrated in the bulbs. Chewing on any part of the plant causes intense gastrointestinal upset, and ingestion of the bulbs can cause more severe poisoning including convulsions, heart abnormalities, and respiratory depression. If you suspect your cats has ingested tulips and daffodils, contact your veterinarian or nearest emergency vet clinic immediately.

If Your Pet May Have Ingested Something Toxic
Contact your veterinarian or nearest emergency vet clinic immediately. Do not wait for symptoms to appear — early intervention significantly improves outcomes.
| Toxic? | Severity | Time to Onset | Commonness | Urgency |
|---|---|---|---|---|
| Yes | Moderate | 1–6 hours | Common (seasonal: spring bulbs, cut flowers) | Urgent |
The Toxic Principle
The dangerous compound in Tulips and Daffodils is Tulipalin A (tulips) and Lycorine (daffodils) — toxic glycosides.
Tulips contain tulipalin A (a lactone) and other allergenic glycosides, most concentrated in the bulb. Daffodils contain lycorine, a toxic alkaloid that causes severe vomiting and diarrhea. Both plants also contain calcium oxalate crystals that cause oral irritation. The bulbs contain the highest toxin concentration — up to 10× more than the stems and leaves. Cut flowers in vases pose a risk because cats may drink the water or chew the stems.
How Much Is Dangerous?
The risk depends on your cats's weight and the amount ingested.
| Pet Weight | Dangerous Amount | Expected Severity |
|---|---|---|
| Any cat (leaf/stem) | Chewing leaves or stems causes oral irritation and GI upset | Mild |
| Any cat (flower) | Eating flowers causes moderate GI symptoms | Moderate |
| Any cat (bulb) | Ingesting a bulb is much more dangerous | Severe |
| Any cat (vase water) | Water from vases containing tulips/daffodils can be toxic | Mild |

Why Tulips and Daffodils Is Dangerous for Cats
Cats are especially vulnerable to tulips and daffodils because they have a significantly smaller body mass and a liver that metabolizes certain compounds differently than humans or dogs. The toxic principle — Tulipalin A (tulips) and Lycorine (daffodils) — toxic glycosides — may accumulate in a cat's system more quickly than in larger animals. Symptoms typically begin within 1–6 hours of ingestion.
Tulips contain tulipalin A (a lactone) and other allergenic glycosides, most concentrated in the bulb. Daffodils contain lycorine, a toxic alkaloid that causes severe vomiting and diarrhea. Both plants also contain calcium oxalate crystals that cause oral irritation. The bulbs contain the highest toxin concentration — up to 10× more than the stems and leaves. Cut flowers in vases pose a risk because cats may drink the water or chew the stems.
