Indoor plants add beauty, freshness, and a calming effect to homes, but for cat owners, plant safety is a serious concern. Cats are naturally curious and often chew on leaves, which can be dangerous if the plant is toxic. One common question among plant lovers is: Are Calathea plants toxic to cats?
The short answer is no—Calathea plants are non-toxic to cats, but there is more you should know before bringing one home. This detailed guide explains Calathea safety, why they are considered pet-friendly, potential mild reactions, and how to keep both your plants and cats safe indoors.
Are Calathea Plants Toxic to Cats?
Calathea plants are non-toxic to cats, according to reputable sources such as the ASPCA (American Society for the Prevention of Cruelty to Animals). This makes them one of the safest indoor plant choices for households with cats. Unlike many decorative houseplants that contain harmful chemicals or sap, Calathea varieties do not produce toxins that can poison cats if chewed or ingested.
Key reasons Calathea plants are considered cat-safe include:
- They do not contain calcium oxalates, which are responsible for mouth irritation in many toxic plants
- They are free from poisonous alkaloids or glycosides
- Ingestion does not cause organ damage or severe illness
If a cat nibbles on Calathea leaves, serious symptoms such as vomiting, seizures, or breathing problems are extremely unlikely. This is why Calathea plants are often recommended as pet-friendly indoor plants for cat owners.
However, “non-toxic” does not always mean “completely harmless.” Cats with sensitive stomachs may still experience mild digestive discomfort if they chew large amounts. Understanding this distinction helps pet owners make informed and responsible choices.
Why Calathea Plants Are Safe for Cats Compared to Other Houseplants
Many popular indoor plants—such as peace lilies, pothos, philodendrons, and dieffenbachia—are toxic to cats and can cause serious health issues. Calathea stands out because it belongs to the Marantaceae family, a group known for being safe for pets.
What makes Calathea safer than other plants:
- Soft, non-toxic leaves with no irritating sap
- No chemical defense toxins, unlike many tropical plants
- Naturally grown for foliage beauty, not chemical deterrence
Common Calathea varieties that are safe for cats include:
- Calathea Orbifolia
- Calathea Makoyana (Peacock Plant)
- Calathea Medallion
- Calathea Lancifolia (Rattlesnake Plant)
Because Calatheas are non-toxic, they are often included in lists of:
- Cat-safe indoor plants
- Pet-friendly houseplants
- Non-toxic plants for apartments
This makes them an excellent choice for homes where cats roam freely. Still, owners should monitor chewing behavior, as excessive leaf consumption can upset digestion—not due to toxicity, but due to plant fiber.
Can Calathea Plants Cause Any Side Effects in Cats?
Although Calathea are not poisonous to cats, mild side effects can still occur in rare cases. These reactions are usually related to overconsumption, not toxicity. Cats that chew on plants frequently may experience temporary digestive discomfort.
Possible mild side effects include:
- Slight vomiting
- Loose stool
- Temporary loss of appetite
These symptoms are generally short-lived and do not require medical treatment. If symptoms persist for more than 24 hours, it is best to consult a veterinarian—not because Calathea is toxic, but to rule out other causes.
To reduce any risk:
- Discourage frequent chewing
- Place plants out of direct reach
- Provide cat grass as a safe alternative
It’s important to note that no life-threatening reactions are associated with Calathea plants. Compared to toxic plants that can cause mouth swelling, kidney failure, or neurological issues, Calathea is one of the safest options available for cat owners.
Tips for Keeping Both Your Cat and Calathea Plant Safe Indoors

Helpful tips for cat-friendly plant care:

From the plant’s perspective:
