My Cat Ate a Lily: What to Do Now
See a vet now
Quick answer
Lilies are highly toxic to cats and can cause fatal kidney failure. Even small amounts of any lily part—petals, leaves, pollen, or water from the vase—require immediate emergency veterinary care. Do not wait for symptoms to appear.
Common causes
True lilies (Lilium and Hemerocallis species)
Easter lilies, tiger lilies, daylilies, Asiatic lilies, and stargazer lilies contain toxins that destroy kidney cells in cats. All parts are dangerous, including pollen that may land on fur and be groomed off.
Lily of the valley
Though not a true lily, this plant contains cardiac glycosides that can cause heart rhythm problems and digestive upset in cats.
Peace lily or calla lily
These are not true lilies but can still cause mouth irritation, drooling, and vomiting due to insoluble calcium oxalate crystals.
Indirect exposure
Cats may ingest lily pollen from grooming their coat, drinking water from a lily vase, or walking through fallen petals and licking their paws.
When to see a vet
- Vomiting (often starting within 2 hours)
- Lethargy or hiding
- Loss of appetite
- Excessive thirst or urination (or complete lack of urination)
- Drooling or pawing at the mouth
- Collapse or weakness
- Any known or suspected lily ingestion—treat as emergency regardless of symptoms
Home care tips
- There is no safe home care for lily ingestion—this is an emergency
- Do not induce vomiting unless specifically instructed by a veterinarian or poison control
- Bring a photo or sample of the plant to the vet for identification
- Note the time of ingestion and any symptoms observed
- Call your vet, emergency clinic, or ASPCA Animal Poison Control (888-426-4435) immediately

FAQ
How much lily is toxic to cats?
Any amount is dangerous. A single bite of a leaf, a lick of pollen, or drinking vase water can cause fatal kidney failure in cats. There is no safe threshold.
What are the first signs of lily poisoning in cats?
Vomiting usually begins within 2 hours. Lethargy and loss of appetite follow. Some cats seem to improve temporarily, but kidney damage progresses silently. By the time increased thirst or decreased urination appears, serious injury may have occurred.
Can cats recover from lily poisoning?
Recovery is possible with immediate, aggressive veterinary treatment started within 18 hours of ingestion. Delayed care often leads to irreversible kidney failure. The prognosis worsens significantly after 24 hours.
Are all lilies equally dangerous to cats?
True lilies in the Lilium and Hemerocallis genera are the most dangerous. Peace lilies and calla lilies cause milder mouth irritation but are still concerning. Lily of the valley affects the heart. When in doubt, assume the worst and seek care.
How can I keep my cat safe from lilies?
Do not bring any lilies into your home or garden if you have cats. Check bouquets received as gifts. Remove lilies from your property. Choose cat-safe alternatives like orchids, roses, or spider plants instead.
