Is Alstroemeria Toxic to Cats? What Pet Owners Should Know
Related pillar guide: Continue with the Alstroemeria growing and cut-flower guide for the broader planning framework.
Quick answer: The ASPCA lists Alstroemeria (Peruvian lily) as non-toxic to cats, but that does not mean it should be eaten. Any plant material can cause vomiting or digestive upset. Confirm the botanical name, keep bouquets out of reach, and contact a veterinarian if a cat eats the plant or develops symptoms.
| Plant name | ASPCA framing | What cat owners should do |
|---|---|---|
| Alstroemeria / Peruvian lily | Listed as non-toxic; ingestion may still cause stomach upset | Prevent chewing, remove fallen plant material, and call a veterinarian if symptoms appear |
| True lilies (Lilium) | Associated with severe kidney injury in cats | Keep the entire plant, pollen, vase water, and bouquets away from cats |
| Daylilies (Hemerocallis) | Also associated with severe kidney injury in cats | Avoid exposure and seek urgent veterinary guidance after suspected ingestion |
| A bouquet labeled only “lily” | Common name is not enough for identification | Confirm the botanical identity before bringing it into a home with cats |

Alstroemeria, also called the Peruvian lily, is a popular garden flower known for its bright blooms and long vase life. The ASPCA lists Peruvian lily (Alstroemeria) as non-toxic to cats, dogs, and horses. It is botanically distinct from true lilies in the Lilium genus, which can cause life-threatening kidney injury in cats.
For planting and year-round maintenance, see our complete Peruvian lily care guide.
An ASPCA non-toxic listing is not an invitation to let pets eat the plant. Chewing any plant material can cause irritation or digestive upset in some animals, so keep flowers, leaves, and stems out of reach when practical.
Alstroemeria and Cats: What the ASPCA Listing Means
The ASPCA lists Peruvian lily (Alstroemeria) as non-toxic to cats, dogs, and horses. That listing distinguishes it from true lilies, but it does not guarantee that chewing plant material will never cause irritation or digestive upset.
Prevent pets from chewing flowers, leaves, or stems. If a pet eats the plant or develops vomiting, diarrhea, drooling, lethargy, or other unusual signs, contact a veterinarian for advice.
Practical Precautions Around Cats
Avoid treating any ornamental plant as risk-free for chewing. Place bouquets and garden plants where curious pets are less likely to reach them, remove fallen plant material, and identify the exact plant if an exposure occurs.
If your pet chews the plant or develops unusual signs, contact your veterinarian or an animal poison-control service for guidance.
The good news is gardeners can still enjoy flowers while creating safer outdoor spaces for cats and dogs.
Peruvian Lily vs True Lilies
One reason people get confused is that Peruvian lilies are not part of the same group as highly dangerous lilies.
A true lily, also called a lily lilium plant, belongs to the Lilium genus. These lilies are toxic and may cause severe kidney damage in cats, even after exposure to pollen or vase water.
Dangerous examples include:
- Easter lilies
- Tiger lilies
- Stargazer lilies
- Asiatic lilies
Peruvian lily is botanically separate from true lilies. The ASPCA lists Alstroemeria as non-toxic to cats, dogs, and horses; true lilies require a much more urgent level of avoidance around cats.
Common names can be misleading, so identify the genus rather than relying on the word “lily.”
Practical Precautions for Homes With Cats
If you love Alstroemeria but also care about pet safety, a few garden design choices can help:
- Place flowers behind taller garden plants or shrubs
- Use raised containers or hanging baskets
- Remove fallen petals and leaves quickly
- Grow cat-accessible herbs nearby, such as cat grass or catnip
- Keep bouquets out of reach indoors
For homes with cats, identify every plant called a “lily.” True lilies (Lilium) and daylilies (Hemerocallis) require especially strict avoidance; unrelated plants that share the common name can present different hazards.
Creating pet-restricted planting and display areas can reduce access while still allowing gardeners to enjoy colorful blooms.
Growing Alstroemeria Responsibly
Many gardeners still grow Peruvian lilies because they are beautiful cut flowers with long-lasting blooms. If you enjoy flower arranging, the Annie’s Annuals guide to best plants for cut flowers offers more garden inspiration.
You can also browse Alstroemeria varieties or grow the colorful Alstroemeria Tricolor – Peruvian Lily, Princess Lily in carefully planned garden spaces.
As with all ornamental plants, placement matters when pets are nearby.
Conclusion
The ASPCA lists Peruvian lily (Alstroemeria) as non-toxic to cats, dogs, and horses. It is not a true lily and is not associated with the kidney toxicity of Lilium and Hemerocallis species.
Even so, prevent chewing and contact a veterinarian if a pet eats plant material or develops unusual signs. Careful identification and placement are more useful than categorical “safe” claims.
