Lilies (Lilium and Hemerocallis species)

Contributor(s): Nicola Bates

Introduction

  • Cats are uniquely sensitive to nephrotoxicity caused by ingestion of plant material from both Liliumand Hemerocallisspecies. Included are:
    • Easter lily ( Lilium longiflorum).
    • Tiger lily ( L.lancifolium, synonym L. tirinum).
    • Japanese show lily ( L. hybridum).
    • Rubrum lily ( L. rubrum).
    • Stargazer lily or oriental lily ( L.orientalis).
    • Numerous Liliumhybrids.
    • Day lilies ( Hemerocallisspecies)   Day lily  .
  • Ingestion of leaves, pollen or flowers from either species results in acute nephrotoxic syndrome that culminates into anuric renal failure.
  • There is no age or breed predilection.
  • Indoor cats are more at risk of exposure.
  • No toxic effects have been observed in rats or rabbits, and dogs that have ingested large quantities develop only mild gastrointestinal upset.
