Is Calathea Toxic to Cats and Dogs?
Calathea plants are listed as non-toxic to cats and dogs by the American Society for the Prevention of Cruelty to Animals (ASPCA). This means that ingestion of this plant is not expected to cause serious or life-threatening illness in pets. The scientific name for this group of plants is Calathea spp., and they belong to the Marantaceae family.
While calathea is considered a safer choice for a home with pets compared to toxic plants, it is not intended to be a food source. It is always best to discourage pets from chewing on or eating any houseplant, regardless of its toxicity status. Even non-toxic plants can cause mild digestive upset if a pet eats a significant amount.

What the ASPCA lists for calathea
The ASPCA maintains a widely referenced database of plants that are toxic and non-toxic to pets. In its entry for Calathea, the organization lists the plant as non-toxic to dogs, cats, and horses. The listing applies to plants in the Calathea spp. genus.
This classification means that the plant does not contain any known toxic principles that would cause poisoning in these animals. As a result, the ASPCA does not list any specific clinical signs of toxicity for calathea because it is not expected to cause them.
What this means for a home with pets
Having a calathea plant in a home with cats or dogs is generally considered safe. If a pet chews on a leaf or stem, it should not lead to a medical emergency. This makes it a popular choice for pet owners who want to have houseplants. Many people seek out plants specifically listed as non-toxic to reduce the risk of accidental poisoning.
However, a non-toxic status does not mean the plant is edible. The main concern with a pet eating any plant matter is the potential for mild gastrointestinal irritation. A pet’s digestive system is not designed to process large quantities of plant material. Ingesting leaves or stems could lead to temporary issues like vomiting or diarrhea.
Points to keep in mind with a non-toxic plant
Even with safe plants like calathea, it is wise to practice general pet safety. Supervising pets around any new item in the home, including plants, is a good habit. Placing plants out of a pet’s easy reach can prevent them from developing a habit of chewing on leaves. This also protects the plant from damage.
Keep these points in mind:
- Digestive Upset: Any plant material can cause mild stomach upset, especially if a pet eats a lot of it. This can include vomiting or loose stools.
- Choking Hazard: Large pieces of tough leaves or stems could potentially pose a choking risk, particularly for small animals that do not chew them thoroughly.
- Pesticides and Fertilizers: Residue from topical pesticides or chemicals from soil fertilizers could be harmful if ingested. Always check the labels of any products used on or near your houseplants.
When to call your vet
A non-toxic listing means the plant is not expected to poison pets, not that eating it is harmless. Call your vet if your pet shows any of the signs below after chewing on a plant.
If your pet eats any part of a calathea plant and shows signs of distress, such as repeated vomiting, diarrhea, or loss of appetite, it is best to contact your veterinarian. For immediate advice, you can also call a pet poison hotline like the ASPCA Animal Poison Control Center at (888) 426-4435. A consultation fee may apply. If possible, tell the veterinarian which plant was eaten, how much, and when it happened.
