Calathea plants are generally considered non-toxic to cats and are widely recommended as a pet-safe houseplant, but eating large amounts can still cause mild stomach upset like vomiting or diarrhea.

Are Calathea Plants Toxic to Cats?

Most reputable pet and plant resources list Calathea (Calathea spp.) as non- toxic to cats, meaning it does not contain the typical plant toxins that cause serious poisoning or organ damage. Veterinary-focused guides note that Calathea is also safe for dogs and humans, making it a popular choice for pet- friendly homes.

What Can Happen If a Cat Eats Calathea?

Even though Calathea is non-poisonous, the leaves are thick and fibrous and can irritate the digestive system if a cat chews or swallows a lot. Reported signs after heavy nibbling include mild gastrointestinal upset such as vomiting, soft stool or diarrhea, drooling, decreased appetite, or general discomfort.

When To Call the Vet

If your cat only nibbles a small piece and acts normal, serious problems are unlikely. Contact a vet promptly if you notice repeated vomiting, persistent diarrhea, refusal to eat, marked lethargy, or symptoms lasting more than a few hours, as any plant ingestion can occasionally unmask other issues.

Safe Houseplant Tips for Cat Owners

  • Place plants where cats are less likely to chew them, even if the plants are considered safe.
  • Offer pet-safe grass or toys so chewing needs are directed away from houseplants.
  • Learn highly toxic plants for cats (for example, lilies and azaleas) and keep those completely out of the home.
