Symptoms reported in cats

Most serious first.

  1. 1
    Vomiting Variable (typically within hours of ingestion). · Saponins throughout the plant irritate the gastrointestinal mucosa, commonly causing vomiting.
  2. 2
    Excess salivation Immediate to rapid (shortly after exposure). · Drooling (hypersalivation) occurs as part of the saponin-driven gastrointestinal irritation and nausea.
  3. 3
    Diarrhea Variable (typically within hours of ingestion). · Saponins irritate the GI tract, causing diarrhea. Unlike true lilies, it does not cause acute renal failure.

Important notes

African Blue Lily (Agapanthus) is often mistaken for a true lily, but it belongs to a different plant family and does not cause the acute kidney failure associated with true lilies (Lilium and Hemerocallis species). However, it is mildly toxic to cats: saponins found throughout the plant can cause gastrointestinal distress (vomiting, drooling, diarrhea) when any part — including the leaves, stems, or roots — is ingested. Cats are sometimes attracted to its grass-like foliage, so households with this plant should monitor access.

  • Symptoms: Vomiting, diarrhea, and excessive drooling are the most common signs of ingestion.
  • Not a true lily: Unlike Lilium or Hemerocallis species, this plant does not cause kidney failure, making it significantly less dangerous — but it is still not safe to ingest.
  • Action: Monitor your cat after any suspected ingestion; contact a vet if symptoms persist or worsen.
