The safety of our feline companions is paramount, making the question of alstroemeria toxic to cats a significant concern for pet owners. Understanding the potential risk requires considering the ASPCA’s comprehensive guide to toxic plants, where alstroemeria is listed as potentially harmful. Veterinarians often advise caution around any non-cat-safe plants, regardless of the severity listed, due to individual sensitivities. While alstroemeria itself might not be acutely poisonous like lilies, the presence of glycosides suggests that ingestion can lead to digestive upset. Recognizing the symptoms, such as vomiting, associated with alstroemeria toxic to cats is essential for responsible pet ownership.

Alstroemeria & Cats: Understanding the Risks
Alstroemeria, also known as Peruvian lilies or Lily of the Incas, are beautiful and popular flowers. However, when you have cats, it’s important to understand potential risks associated with your pets interacting with certain plants. Let’s address the question: Is alstroemeria toxic to cats?
Is Alstroemeria Actually Toxic to Cats?
The short answer is: while not deadly, alstroemeria is considered mildly toxic to cats. It’s crucial to understand what "mildly toxic" means in this context. It doesn’t mean a single nibble will be fatal, but it can certainly cause unpleasant symptoms.
What Makes Alstroemeria Problematic?
Alstroemeria contains compounds that, when ingested, can irritate a cat’s gastrointestinal tract. These compounds aren’t nearly as potent as those found in true lilies (like Lilium and Hemerocallis species), which are extremely dangerous and can cause kidney failure in cats.
Misidentification and Confusion with True Lilies
A significant part of the concern surrounding alstroemeria stems from its common name, "Peruvian Lily." This can lead to confusion with the highly toxic true lilies. It’s absolutely vital to differentiate between alstroemeria and true lilies.
- Alstroemeria (Peruvian Lily): Mildly toxic, causing gastrointestinal upset.
- True Lilies (e.g., Asiatic, Easter, Tiger lilies): Highly toxic, causing kidney failure and potentially death.
Pay close attention to the scientific name of any "lily" before bringing it into a home with cats.
Potential Symptoms of Alstroemeria Poisoning in Cats
If your cat eats alstroemeria, it might exhibit the following symptoms:
- Gastrointestinal Upset: This is the most common symptom.
- Vomiting
- Diarrhea
- Loss of appetite
- Oral Irritation:
- Excessive drooling
- Pawing at the mouth
- Lethargy: A general lack of energy and reluctance to move.
It’s important to note that the severity of symptoms can vary depending on the amount ingested and the cat’s individual sensitivity.
What to Do If Your Cat Eats Alstroemeria
-
Identify the Plant: Confirm that your cat actually ingested alstroemeria and not a true lily. This is crucial for determining the level of urgency.
-
Remove Access: Prevent your cat from eating more of the plant.
-
Monitor Symptoms: Watch your cat closely for any of the symptoms listed above.
-
Contact Your Veterinarian: It’s always best to consult with your veterinarian, even if the symptoms appear mild. They can advise you on the best course of action and monitor for potential complications.
- Provide your veterinarian with details about the amount ingested (if known) and the specific symptoms your cat is exhibiting.
-
Supportive Care: Your veterinarian may recommend supportive care, such as fluids to prevent dehydration, anti-emetics to control vomiting, or a bland diet to soothe the gastrointestinal tract.
Prevention is Key: Keeping Cats Safe
The best way to protect your cat from alstroemeria poisoning is to prevent them from accessing the plant in the first place.
Safe Alternatives to Alstroemeria

Strategies for Keeping Alstroemeria Out of Reach
If you absolutely must have alstroemeria in your home, consider these precautions:
- Elevated Placement: Place the flowers in a location that is completely inaccessible to your cat, such as a high shelf or a room they cannot enter.
- Protective Barriers: Use protective barriers, such as cages or glass enclosures, to prevent your cat from reaching the flowers.
- Deterrents: Some cat owners use deterrent sprays (formulated for plants and safe for pets) to discourage cats from approaching the plants. Test a small area first.
- Education: Educate all members of your household about the potential risks and the importance of keeping the flowers out of reach.
