What Lilies Are Poisonous To Cats?

Lilies are beautiful flowers that are often used in ornamental floral arrangements for holiday celebrations, weddings, and funerals.

Lilies of the genera Lilium and Hemerocallis (Day Lilies) have been shown to cause nephrotoxicity (kidney disease) in cats.

It isn’t just a bouquet of flowers that can be deadly, our gardens can also prove hazardous to our cats.

I know my parent’s garden contains many plants that are poisonous to pets including Day Lilies, Christmas Lilies and Easter Lilies.

Neighbouring cats and dogs often enter the garden at free will, posing a deadly risk to their lives.

What Happens If My Cat Eats A Lily?

The exact toxin in lilies that is poisonous to cats hasn’t been identified yet.

What we do know is that this toxin causes acute kidney failure in cats.

Cats are extremely sensitive to lilies where even the smallest ingestion of any part of the plant can result in severe, acute kidney failure.

Cats have known to be poisoned by ingesting vase water or even licking pollen that has brushed onto their fur.

All parts of the plant are poisonous including the pollen, leaves, flowers and bulbs and can result in kidney failure within 24-72 hours of ingestion.

Although the exact toxin is unknown, we do know that it is water-soluble.

What Are The Signs Of Lily Poisoning?

The signs that indicate that your cat may have eaten a lily are not particularly exclusive to lily toxicity.

These signs are more indicative of a problem with the kidneys.

Signs that you may notice include:

  • Depression
  • Inappetence (not eating)
  • Increased drinking
  • Decreased or no urination at all
  • Vomiting
  • Wobbliness

The most important thing is if you have a suspicion that your cat has had contact with a lily, you need to seek veterinary attention immediately.

Can Lily Poisoning Be Treated?

It is crucial that if you think your cat has ingested or come into contact with a lily plant that you get them to a veterinary clinic immediately.

Without aggressive treatment, many cats do die.

There is no antidote for lily poisoning, however prompt veterinary intervention can improve prognosis and some cats will survive, albeit with kidney damage.

If you witnessed your cat eating a lily leaf or petal your veterinarian may start with decontamination i.e. they will induce vomiting and give a substance called activated charcoal to bind the poison in the stomach and intestines.

However, the most important part of treatment is aggressive fluid therapy.

Your cat will be placed on an IV drip and likely have their bladder catheterised so that urine output can be monitored.

Blood tests for kidney function and monitoring of urine output will help determine if treatment is working.

It can take a few days before signs of kidney damage show, but treatment needs to be started very quickly to help improve the chances of recovery.
