Peruvian lilies (Alstroemeria) are considered to be mildly toxic to cats but not highly dangerous like true lilies (Lilium species) or daylilies. They contain a toxin called tulipalin A, which can cause mild stomach upset, vomiting, diarrhea, and irritation if ingested in large quantities. Unlike true lilies, Peruvian lilies do not cause kidney failure in cats. Generally, the toxicity is mild and symptoms tend to resolve on their own, but ingestion in large amounts may cause discomfort. It is advised to keep these plants out of reach to prevent any ingestion by cats.
Toxicity Level
- Peruvian lilies are the least toxic among lily-like plants and only cause mild gastrointestinal upset in cats if ingested in large quantities.
- True lilies and daylilies are highly toxic and can cause fatal kidney failure in cats.
- Other lilies like calla lilies and peace lilies cause milder symptoms like mouth irritation but not kidney failure.
Symptoms to Watch For
- Mild stomach upset
- Vomiting
- Diarrhea
- Skin irritation (less common)
Precautionary Measures
- Avoid having Peruvian lilies within easy reach of cats.
- Seek veterinary advice if a cat ingests part of the plant to monitor and manage symptoms promptly.
In summary, Peruvian lilies are mildly toxic to cats and usually cause only mild stomach upset, not the severe toxicity associated with true lilies.
