Is Peruvian Lily Toxic to Cats?
Also known as: Alstroemeria, Lily of the Incas, Alstroemeria aurea · Alstroemeria aurea
What makes it toxic
Tulipalin A, a contact irritant in the sap and tissue. It causes mild oral and gastric irritation, far milder than true Lilium or Hemerocallis toxicity.
Warning signs to watch for
Drooling, mild vomiting and slight stomach discomfort within hours of chewing stems or leaves. Signs fade quickly.
What to do if your cat eats it
Remove plant material, offer water and monitor. No emergency is expected, but call your vet if vomiting persists or the cat stops eating.
Common questions
Is it safe as a cut flower in a cat household?
It is one of the safest lily-named flowers — florists favor it partly for that reason. Still, keep a cat from chewing stems.
Why do florist lilies confuse owners?
Alstroemeria looks lily-like but is not a Lilium. True lilies are lethal to cats; Peruvian lilies are not. Learn the leaf pattern — alstroemeria leaves are twisted.
Can it cause kidney failure like an Easter lily?
No. There is no documented nephrotoxicity in cats from alstroemeria, which is why it rates mild rather than severe.
