Lilies are widely admired for their vibrant colors and pleasant fragrance, making them a popular addition to summer bouquets and gardens. However, it’s important for cat parents to be aware of the potential dangers these flowers pose.  

Cats are naturally curious creatures, often attracted to the bright hues and strong scents of lilies, particularly when they are in full bloom during the summer months. Unfortunately, even ingesting a small amount of any part of the lily—whether the petals, leaves, or pollen—can lead to severe kidney failure in cats, which can be life-threatening.  

Understanding this risk is essential for keeping your feline companion safe during the warmer seasons. 

Lily Toxicity 

According to PetSure claims data 2023, the number one toxin ingested by cats was lilies. Lily toxicity in cats can occur through exposure to Lilium and Hemerocallis plant species, including true lilies, daylilies and hybrids.  

The average treatment for the ingestion of lilies was $1,845 with the highest claim being $22,423^. 

What is Lily Toxicity? 

Lily toxicity in cats occurs when they come into contact with true lilies (Lilium) or day lilies (Hemerocallis species). Although the exact mechanism of toxicity remains unclear, even a small amount of any part of the plant—whether it be the leaves, flowers, stems, or pollen—can cause serious illness or death. The toxins target the kidneys, leading to kidney injury, failure, and in severe cases, death. 

Toxic Lily Species 

Several species of lilies are known to be toxic to cats, including: 

  • Day lilies (Hemerocallis spp.) 
  • Asiatic lilies (Lilium asiatic) 
  • Tiger lilies (Lilium lancifolium) 
  • Easter lilies (Lilium longiflorum) 
  • Stargazer lilies (Lilium orientalis) 
  • Rubrum lilies (Lilium speciosum) 
  • Western/wood lilies (Lilium umbellatum) 

Hybrid species can also be toxic. If you are uncertain about the type of plant, it’s safest to keep it out of your pet’s reach. 

Signs of Lily Toxicity 

Common symptoms of lily ingestion range from a sudden disinterest in food, vomiting, lethargy or drooling, to excessive drinking or urination, crying, and generalised weakness. Seizures may also occur as a result of kidney injury or failure. 

Immediate treatment is critical upon the suspicion of lily exposure as it typically involves hospitalisation, as well as efforts to stop toxin absorption to prevent kidney injury and/or seizuring. If kidney damage is apparent, treatment may include managing symptoms through intravenous fluids and appropriate medications.

Common signs of lily toxicity include: 

  • Loss of appetite 
  • Vomiting 
  • Lethargy or depression 
  • Fever 
  • Excessive urination or inability to urinate 
  • Seizures (in some cases) 

These symptoms are often linked to acute kidney failure, so prompt intervention is critical. 

Managing Lily Toxicity 

Lily toxicity is a medical emergency. If you suspect exposure, your veterinarian may attempt to prevent toxin absorption by administering activated charcoal and providing intravenous fluids to support kidney function. Treatment may also include anti-nausea medication, seizure control, and other supportive therapies. 

While some cats may experience long-term kidney damage, early and aggressive treatment can lead to a full recovery in many cases. Blood tests may be needed after treatment to monitor kidney function. 

Treatment Costs 

*PetSure claims data 2023 indicates that the average cost for treating lily toxicity is $431 per treatment. The highest recorded cost for a single treatment was $3,046.
