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.

  • Keep the plants in hanging pots and stands to avoid reaching your cats to your plants.
  • Cats are very sensitive to smell, so you can make your plants smell unpleasant to them by using a repellent spray.

  • Grow thorny plants like roses and cacti around your calathea to keep cats away.
  • You can also plant cat grass, basil, mint, catnip, lavender, and cat thyme around calathea plants to prevent cats from chewing them.
  • Frequently trim your plants because their flowers and leaves can attract cats.
  • You can also create your plant room with abundant sunlight and lock it to avoid cat access.
