Peruvian lily

Alstroemeria spp.

Conflicting guidance — use caution

Peruvian lilies can cause stomach upset when eaten. Published guidance differs on whether to call them non-toxic or mildly toxic, so we do not recommend them as cat-safe plants.

What this guide covers: Alstroemeria species and garden cultivars only. These are different from true lilies and daylilies; an unidentified lily exposure needs prompt veterinary advice.

Prevent chewing and do not choose Peruvian lily as a cat-safe alternative. An unidentified lily exposure needs prompt veterinary advice.

Why the guidance differs

ASPCA labels Alstroemeria non-toxic; Pet Poison Helpline describes tulipalin A and gastrointestinal effects after larger ingestions.

A disagreement between references does not cancel a toxicity warning. We keep those warnings visible while the assessment remains unresolved.
