Toxicité du Lys chez les Chats : Chaque Partie est Mortelle
Toutes les parties des lys — pétales, feuilles, pollen, et même l'eau du vase — causent une insuffisance rénale chez les chats. Gardez les lys hors de votre maison.
Lilies are one of the most dangerous plants for cats. Every part of the plant is toxic: petals, leaves, stems, pollen, and even the water in the vase. Ingesting a small amount — as little as licking pollen off their fur or drinking vase water — can cause fatal kidney failure within 72 hours. There is no antidote. RVC provides emergency treatment for lily toxicity. Call +853 6677 6611.
Points Clés
- ALL parts of lilies are toxic to cats: petals, leaves, pollen, stems, and vase water
- Even small amounts cause fatal kidney failure
- Onset of symptoms: vomiting, lethargy, loss of appetite within 6-12 hours
- Kidney failure develops within 24-72 hours
- Early aggressive IV fluid therapy may save the kidneys
- There is NO antidote — prevention is the only protection
Which Lilies Are Toxic?
The most dangerous are true lilies (Lilium species and Hemerocallis species): Easter lily, Tiger lily, Asiatic lily, Stargazer lily, Oriental lily, Daylily, and Japanese Show lily. ALL are equally toxic. Lily of the valley (Convallaria majalis) is also toxic but belongs to a different plant family — it causes heart problems, not kidney failure. Calla lilies and peace lilies (Zantedeschia, Spathiphyllum) are less toxic but can cause mouth irritation and drooling. For cat safety, keep ALL lilies out of your home.
How Lily Toxicity Works
The exact toxin in lilies has not been identified, but its effect is well-documented. Within hours of ingestion, the toxin destroys kidney tubule cells. The kidneys lose their ability to filter waste products, regulate electrolytes, and produce urine. As toxins build up in the blood (uremia), the cat becomes progressively more ill. The damage is often irreversible if not caught within 18-24 hours. Even with prompt treatment, some cats don't recover kidney function.
Symptoms and Timeline
0-6 hours: may have no symptoms. 6-12 hours: vomiting (often severe), lethargy, loss of appetite, depression. 12-24 hours: continued vomiting, dehydration, increased thirst initially (then decreased as kidneys fail). 24-48 hours: kidneys begin to fail — decreased urination, weakness, disorientation, and worsening dehydration. 48-72 hours: complete kidney failure, seizures, coma, and death without treatment. Early symptoms can be subtle — any cat with possible lily exposure should be treated immediately.
Treatment
If lily exposure is suspected, the cat needs immediate veterinary care — even if no symptoms are present. Treatment: 1) Induce vomiting if within 2 hours of ingestion. 2) Activated charcoal to bind toxin. 3) Aggressive IV fluid diuresis for 48-72 hours to flush kidneys and maintain blood flow. 4) Monitor kidney values (BUN, creatinine, SDMA) every 12-24 hours. 5) If kidneys fail, dialysis (peritoneal or hemodialysis) at specialty centers may be needed. 6) Prognosis is good if treatment starts before kidney values rise; guarded to poor if treatment is delayed.
