The varieties, including calathea ornata, calathea rufibarba, calathea crocata, calathea makoyana, calathea sanderiana, calathea lancifolia, and calathea zebrina are completely safe for cats.

However, excessive ingestion of Calatheas can induce irritation in your cats and cause slight vomiting or diarrhea. 

Cats are curious pets and like to explore their surroundings, so you should not keep an eye out for your cats when they get near this plant.

The leaves of Calathea can become quite big, and your cat may get easily attracted to them to choke.

Fertilizers applied to calathea can be harmful to cats.

Besides, if consumed, fertilizers, insecticides, or any chemical applied to calathea may harm the furry pet.

Pet Poison Helpline states that fertilizers contain iron, copper, boron, zinc, and molybdenum, when ingested, can mildly or severely harm your cats based on the dosage.

Besides these concerns, you do not have to worry about keeping your Calathea and your cats together.

What Makes Calathea Cat Friendly?

Calatheas are a great companion for your feline friends because they do not have thorns or sap oozing out from them.

Moreover, their stems, leaves, roots, and flowers do not contain toxic substances like calcium oxalates, so cats have no risk of extreme irritation and organ failure when even swallowed.

Cats are very clumsy ramblers that can get covered with pollen grains while playing around. For example, the pollen grains of lily, when they come in contact with the whiskers of cats, can cause renal failure.

Besides, the water formed around the stem during transpiration and in the pot’s saucer of some plants can also be toxic to cats. 

Fortunately, Calatheas never leave excessive water near them. These plants require very little water to live and do not shed pollen grains that can irritate your cats.

When Is Calathea Unsafe for Cat? 

Despite being predominantly carnivores, cats may occasionally nibble on plants in the wild, either for the added nutrients or fiber they provide or because they enjoy the flavor.

According to the American Association for the Advancement of Science, grass munching helps pets expel intestinal parasites.

Moreover, cats might crave a different texture or a different fiber in their mouth.

Many plants are rich in fibers that help regulate the digestive system, so the feeling of ease can induce your cat to eat plants.
