Are Daylilies Poisonous to Cats?

In this article, we’ll explore why daylilies are poisonous to cats, what symptoms to watch for if your cat ingests them, how to treat lily poisoning, and how to keep your cat safe from these beautiful but dangerous plants.
What Are Daylilies?
Before diving into the risks, let’s first understand what daylilies are. Daylilies belong to the Hemerocallis genus and are not true lilies, although they are closely related. Their vibrant flowers come in various colors, including yellow, orange, pink, and red. Gardeners love them because they’re hardy and bloom beautifully during the summer months. However, despite their beauty, daylilies can be deadly to cats.
Why Are Daylilies Poisonous to Cats?

The exact toxin in daylilies that harms cats has not been fully identified by veterinarians and scientists. However, what is known is that cats have an extreme sensitivity to daylilies. When cats ingest any part of the plant, it leads to severe damage to their kidneys. This can result in kidney failure within just a few days if untreated, making it a life-threatening situation.
Are daylilies poisonous to cats because of their chemical makeup, or because cats’ bodies simply can’t process certain components of the plant? Either way, the outcome is dangerous, and cat owners must recognize the threat.

As daylily poisoning begins to affect the kidneys, cats may become dehydrated. This can show up as sunken eyes, dry gums, and infrequent urination. - Excessive Thirst or Urination
The early stages of kidney failure can cause your cat to drink and urinate excessively. Over time, however, they may stop urinating altogether, which is a sign of severe kidney damage. - Disorientation or Seizures

If possible, remove the daylily plant or isolate your cat from the area where the plant is located. This helps prevent further ingestion or contact with the poisonous plant. -

Preventing Daylily Poisoning in Cats

The best way to keep your cat safe from daylilies is by preventing exposure. Here are some tips:
