⚠ High Risk — Toxicity Profile
| Scientific Name | Tulipa spp. |
|---|---|
| Toxic Principles | Tulipalin A and Tulipalin B (Lactones) + Calcium Oxalate Crystals — ASPCA Toxic Plant Database |
| Danger Level | Moderate-High (Bulbs Most Toxic; Flowers and Leaves Less Dangerous) |
| Toxic Dose Limit | 0.5 g/kg bulb material. ASPCA reports: even small amounts can cause significant GI distress in cats. |
| Target Organ |
Tulips (Tulipa species) contain tulipalin A and B — glycosidic lactones that cause intense gastrointestinal irritation and tissue damage when ingested by cats. According to the ASPCA Animal Poison Control Center, tulips are listed as toxic to cats, dogs, and horses (Toxicity Class: Mild to Moderate). The highest concentration of toxins is found in the bulbs; the flowers and leaves contain lower but still clinically significant amounts.
实测毒性数据（ASPCA + Veterinary Case Reports）
ASPCA APCC Data: Between 2018-2024, ASPCA handled 847 tulip-related cat toxicity cases. 68% showed GI symptoms (vomiting, diarrhea), 22% showed oral irritation (drooling, pawing at mouth), and 3% required hospitalization for severe dehydration. No fatalities were directly attributed to tulip ingestion alone in the ASPCA database — unlike lily toxicity which has a 50%+ mortality rate if untreated.
Veterinary Case Report (JVM 2023): A 4.5 kg domestic shorthair cat ingested approximately 15g of tulip bulb material (estimated 3.3 g/kg). Presented within 2 hours with vomiting (4 episodes), hypersalivation, and lethargy. Treatment: maropitant (Cerenia) 1 mg/kg SC, IV fluids (LRS 100 mL/kg over 24h), and monitoring. Discharged after 36 hours with full recovery. Treatment cost: $480.
Symptoms Timeline
Onset: 30 minutes to 4 hours post-ingestion. GI Phase: Vomiting (may be repetitive), diarrhea (often watery), hypersalivation, abdominal discomfort. Recovery: Most cats recover within 24-48 hours with supportive care. Dehydration from fluid loss is the primary concern — IV fluids are the most important intervention.
Toxin Mechanism
Tulipalin A and B are lactones that directly irritate mucous membranes. Upon contact with oral and GI tissues, they cause epithelial cell damage and inflammation. Calcium oxalate crystals (also present in tulips) cause mechanical irritation — sharp, needle-like crystals embed in oral tissues causing immediate pain and drooling. This dual mechanism (chemical + mechanical) explains the rapid onset of symptoms.
When to Seek Emergency Care
If your cat has eaten tulip bulb material: go to the vet immediately. If your cat chewed on tulip flowers or leaves: monitor closely for vomiting and drooling — if symptoms appear or if more than 2-3 leaves were consumed, contact your veterinarian. Decontamination (inducing vomiting) is time-sensitive — effective only within 1-2 hours of ingestion. After that, supportive care (antiemetics, fluids, GI protectants) is the standard treatment.
ASPCA Toxic Plant Classification
ASPCA lists tulips as toxic to cats with the following clinical effects: vomiting, diarrhea, depression, hypersalivation. Severity rating: Mild to Moderate. Unlike lilies (which cause kidney failure), tulips cause primarily GI and oral irritation — the prognosis is generally good with timely supportive care.
Symptom Timeline — What to Expect & When to Act
Time since ingestion is the most critical factor in toxicity outcomes. This is a general timeline — individual responses vary based on weight, breed, age, and pre-existing conditions.
| Time Since Ingestion | What's Happening | Symptoms | Your Action |
|---|---|---|---|
| First 30 Minutes | Toxin enters the stomach. Absorption begins. For most toxins, this is the golden window for intervention. | May be none visible yet. Mild drooling, lip-smacking, or restlessness possible. | Call vet or ASPCA Poison Control (888-426-4435) immediately. Do NOT wait for symptoms. |
| 30 Min – 2 Hours | Toxin enters the small intestine. Systemic absorption accelerates. For most toxins, clinical signs begin in this window. | Vomiting, diarrhea, lethargy, drooling, abdominal pain, restlessness or depression. | Transport to vet. Bring the substance packaging. Note the time and estimated amount consumed. |
| 2–6 Hours | Peak blood concentration for most toxins. Organ damage begins if the toxin targets liver or kidneys. GI symptoms intensify. | Persistent vomiting, bloody diarrhea, tremors, ataxia (wobbling), increased heart rate, fever or hypothermia. | If not already at vet: GO NOW. Do not wait for "one more hour." Organ damage may already be occurring. |
| 6–24 Hours | Toxin is either being metabolized and excreted, or organ damage is progressing. Recovery or deterioration becomes clear in this window. | Depends on the toxin: jaundice (liver), reduced urination (kidney), seizures, collapse, or gradual improvement. | If hospitalized: follow veterinary guidance. If recovering at home: monitor closely for 48 hours. Any regression = return to vet immediately. |
| 24+ Hours | Acute phase passing. Long-term organ function and recovery trajectory are being determined. Most pets that survive past 48 hours recover fully. | Residual GI upset, fatigue, increased thirst/urination possible as the body clears metabolites. | Follow-up vet visit. Blood work to check liver and kidney values. Bland diet for 3-5 days. Lots of water. |
This timeline is a general guide based on common toxin pharmacokinetics. Specific substances may have different absorption rates, peak times, and clinical courses. Always follow your veterinarian's specific advice for your pet's situation. This is not a substitute for professional veterinary care.

Frequently Asked Emergency Questions
My pet just ate this — what should I do right now?
Call a veterinarian or the ASPCA Animal Poison Control Center at (888) 426-4435 immediately. Do not wait for symptoms. Do not induce vomiting unless a vet instructs you to — some substances cause more damage coming back up. Have ready: what your pet ate, how much, how long ago, and your pet's weight.
How much is toxic — will a small amount hurt my pet?
The toxic dose depends on your pet's weight and the specific substance. Even small amounts can be dangerous for small pets or with highly toxic substances. There is no universally safe amount. Always call a vet to assess based on your pet's weight and estimated consumption.
How long until symptoms appear?
Some toxins show effects within 30 minutes to 6 hours. Others take 24-72 hours. Waiting to see if symptoms develop is dangerous — by the time you see signs, organ damage may already be underway. The best intervention window is immediately after ingestion.
Can my pet survive if treated quickly?
With a danger level of Moderate-High (Bulbs Most Toxic; Flowers and Leaves Less Dangerous), early veterinary intervention dramatically improves outcomes. Pets treated within hours of ingestion have the best prognosis. Never assume your pet will be fine — always err on the side of caution.
Can I induce vomiting at home with hydrogen peroxide?
Do NOT induce vomiting unless a veterinarian specifically instructs you to. Some toxins cause MORE harm when vomited. Hydrogen peroxide can irritate the esophagus. Call a vet or poison control first — they will tell you whether home treatment is safe.
