Lilies are among the most popular flowers in bouquets, especially around Easter and Mother’s Day. For cats they are one of the most dangerous things you can bring into the house.
This is one topic where there is no nuance: keep true lilies and daylilies out of any home with a cat.
Which lilies are dangerous
The FDA warns that lilies in the “true lily” (Lilium) and daylily (Hemerocallis) families are very dangerous for cats. These include Easter lilies, tiger lilies, Asiatic and Oriental lilies, and daylilies.
How little it takes
According to the FDA, the entire plant is toxic: stem, leaves, flowers, pollen, and even the water in the vase.
A cat that eats a small piece of a leaf or petal, licks a few pollen grains off its fur while grooming, or drinks the vase water can develop fatal kidney failure in as little as three days.
What to do
- Call your veterinarian or a pet poison control line immediately if your cat may have eaten any part of a lily, its pollen or the vase water.
- Take the plant or a photo with you, so the vet can identify it.
- Do not wait for symptoms. Treatment works best when started early.
Early signs can include vomiting, drooling, lack of appetite and lethargy. By the time kidney damage shows, treatment is much harder.
Many poisonings come from bouquets given as gifts. If you have a cat, ask florists and friends to leave lilies out.
The urinary emergency guide covers another situation requiring prompt attention. The carrier comparison keeps transport equipment ready independently of a symptom or exposure.
