A flower that’s poisonous to one particular mammal …
If you have a cat, keep this plant far away from him. Easter lilies are extremely poisonous to cats.
Native to Taiwan and the Ryukyu Islands of Japan, Easter lilies (Lilium longiflorum) are popular flowers at this time of year. Unfortunately every part of the plant is poisonous to cats: the flowers, the leaves, the stem, even the pollen.
Easter lilies are so poisonous to cats that if the pollen touches her and she grooms it away, it will poison her. The result is severe kidney failure.
The poisoning occurs quickly. Signs are evident within 6-12 hours of exposure. There is no antidote but immediate veterinary attention will improve the cat’s chance to live.
The Pet Poison Helpline recommends:
If your cat is seen consuming any part of a lily, bring your cat (and the plant) immediately to a veterinarian for medical care.Pet Poison Helpline — Lilies Poisonous to cats
Do you have a dog? No worries. Easter lilies are not poisonous to dogs. This message only applies to cats.
p.s. Members of the Lilium genus are favorite foods for deer. I have not seen deer eating Easter lilies but I bet they love them.
