The Hidden Dangers: Lily Toxicity in Cats and Other Household Plants to Avoid in Australia


The Hidden Dangers of Lily Toxicity in Cats

Our furry feline companions bring immense joy into our lives. As responsible pet owners, it is crucial to create a safe environment for them, especially when it comes to household plants. While plants can add beauty and vibrancy to our homes, some can be toxic to our pets and pose serious health risks.

Lily toxicity in cats


Lilies, especially ones belonging to the Lilium or Hemerocallis species are one of the most hazardous plants for cats. All parts of the lily plant, including the petals, leaves, stems and even pollen, are toxic to felines. The exact toxic compound is still not fully understood, but even a small amount can have devastating effects on a cat’s health. It is not uncommon for us to see patients who had only brushed past this plant and licked a bit of the pollen to cause illness.

If you suspect your cat has had even minor contact with a Lily plant, please contact the clinic immediately for advice from our team on (03) 8373 0301.

Clinical Signs

When a cat eats any part of the lily, it can lead to acute or sudden-onset kidney failure. The onset of clinical signs usually occurs within a few hours to a day after ingestion. Common signs of lily toxicity include:

  • Vomiting
  • Loss of appetite
  • Lethargy
  • Increased thirst and urinating
  • Dehydration
  • Drooling
  • Seizures and tremors
  • Coma (in severe cases)


Time is of the essence in treating Lily toxicity to prevent irreversible kidney damage.

Our vets may initiate treatment by inducing vomiting followed by giving activated charcoal to reduce absorption. Blood testing is also performed to look for any signs of kidney damage. Any seizure activity is also controlled accordingly. Intravenous fluids are then given at a higher rate to support kidney function and prevent kidney failure. This is given for at least 48-72 hours to support kidney function and/or treat signs of kidney failure.


The prognosis of lily toxicity cases depends on how quickly treatment is sought and initiated. If treatment is started early, some cats may recover fully. However, in severe cases or when treatment is delayed, the damage to the kidneys can be irreversible, leading to long-term kidney problems or even death.

Protecting our beloved feline companions from toxic household plants is an essential responsibility for any cat owner. Lilies stand out as one of the most dangerous plants amongst those commonly found in the household. Swift action and immediate veterinary care are crucial if exposure occurs.

    From initial phone call to book an appointment to leaving after the appointment, there was kindness shown to my beloved cat the entire time. I was nervous as I'd had some challenging visits to other vets years ago, but everything was … More considered for both my kitty and I. Cannot recommend the team more highly.

    Was able to accomodate Rufus so quickly after he cut his paw. Was able to fit me in again when he got to his bandage when I wasnt paying attention. 10/10 service and staff!
