Plant safety record
Easter Lily
Lilium longiflorum
Easter lilies are extremely dangerous to cats. A cat does not have to eat a whole flower to be at risk—chewing a leaf, licking pollen from its coat, or drinking vase water can be enough to cause severe kidney injury. Dogs do not develop the same lily-related kidney failure, though eating the plant may still upset the stomach.

Cats
TOXIC
Keep Easter lilies out of any home a cat can enter. Every part of the plant is a concern, including the flowers, leaves, stems, pollen, roots, and water from the vase.
Dogs
NON-TOXIC
Dogs are not known to develop the severe kidney injury seen in cats. They may still vomit or have diarrhea after eating plant material, so call your veterinarian if your dog is unwell or ate a large amount.
Quick answer
For cats, an Easter lily exposure is an emergency even when the amount seems tiny. Do not wait to see whether symptoms develop. Early veterinary treatment gives a cat the best chance of avoiding permanent kidney damage.
For dogs, the risk is different. Easter lilies are not known to cause the same acute kidney failure, but chewing the plant can still lead to stomach upset.

How cats are exposed
Most people picture a cat biting into a flower, but that is only one way exposure happens. Pollen can fall onto a table, floor, or the cat’s coat. The cat may later swallow it while grooming. Cats can also drink from a vase or nibble a leaf while no one is watching.
Because the dangerous amount can be very small, moving the bouquet to a higher shelf is not a reliable solution. Pollen drops, leaves fall, and curious cats climb. The safest choice is not to keep true lilies in a home with cats.
Signs and timing
Early signs can include vomiting, drooling, poor appetite, and unusual tiredness. These may begin within hours, but a cat can still be in danger before anything looks wrong.
As kidney injury develops, a cat may become dehydrated or urinate more than usual. Later, urine production may fall as kidney failure becomes severe. Waiting for these later signs can mean losing valuable treatment time.
What to do right now
Call your veterinarian, an emergency veterinary hospital, or an animal poison-control service immediately. Say that the plant may be an Easter lily or another true lily and describe every possible kind of contact, including pollen or vase water.
Bring the plant, its label, or a clear photo if you can do so safely. That can help the veterinary team identify what the cat encountered. Do not make the cat vomit or try a home remedy unless a veterinary professional specifically tells you to.
What to tell the veterinary team
Share when the exposure may have happened, which part of the plant was involved, and whether pollen was on the cat’s face or coat. Mention any vomiting, appetite change, lethargy, drinking, or urination changes you have noticed.
It is fine if you do not know the exact amount. With Easter lilies, the possibility of exposure matters more than trying to prove how much was swallowed.
Identity and lookalike scope
This page is about Easter lily, Lilium longiflorum, a true lily with large white trumpet-shaped flowers. The word “lily” also appears in the common names of unrelated plants, and those plants do not all cause the same kind of poisoning.
If the label is missing, do not rely on the common name alone. Treat a possible true-lily exposure as urgent while a veterinarian or poison-control specialist helps identify the plant.
A safer choice for homes with cats
The easiest prevention step is simple: do not bring Easter lilies or other true lilies into the house. Check mixed bouquets before they come through the door, especially around Easter, Mother’s Day, and other occasions when lilies are common.
If someone sends flowers, remove the entire bouquet from the cat’s environment until every plant in it has been identified. A few grains of pollen are easy to miss.
