To cats, yes, and seriously. Daylilies can cause fatal kidney failure in cats, just like true lilies. Dogs usually get no more than a mild stomach upset.
Daylilies (Hemerocallis) aren't true lilies, but they're just as dangerous to cats. Each flower lasts only a day, hence the name. They're among the most common garden perennials, often planted along borders and verges, so outdoor cats can reach them easily. The ASPCA lists every variety as toxic to cats, including the common orange day lily.
In cats, vomiting, drooling, loss of appetite and lethargy start within a few hours and may seem to settle. Kidney failure then develops over one to three days: the cat drinks and urinates more at first, then little or not at all, and becomes weak and withdrawn. Dogs usually get no more than a mild stomach upset.
If your cat has chewed any part of the plant, licked the pollen or drunk the vase water, take it to a vet immediately, without waiting for symptoms. Treatment with IV fluids started early, ideally within 18 hours, usually prevents kidney damage. Wipe pollen off the fur and face so your cat can't lick more off, and bring a piece of the plant. A dog only needs a vet if vomiting persists.
