Pet safety summary
Common name: Lily
Scientific name: Lilium spp. and Hemerocallis spp.
True lilies and daylilies are among the most urgent plant exposures for cats. Even small exposures can be serious for cats, including pollen or vase water. Dogs may develop stomach upset after chewing lilies, but the cat risk is the major emergency concern.
Is it toxic to cats?
For cats, treat any exposure to a true lily or daylily as urgent. Do not wait for vomiting, lethargy, or appetite changes before calling a veterinarian or poison hotline.
Is it toxic to dogs?
Dogs are generally less sensitive than cats to true lilies, but chewing plant material can still cause vomiting or diarrhea. Call your veterinarian if a dog ate part of a lily, especially a large amount.
Symptoms to watch for
- Vomiting or drooling
- Lethargy or loss of appetite
- Increased thirst or urination changes in cats
- Possible kidney injury in cats
Symptoms can vary by pet size, amount eaten, plant part, and health history.
What to do if your pet ate it
