Is Calathea Safe for Cats? Good News for Owners

Last updated: April 10, 2026

If you are a cat owner who loves houseplants, you know the challenge: finding plants that are beautiful, interesting, and genuinely safe for your feline housemate. The good news is that calathea checks every box. Calathea plants — often called prayer plants due to their habit of folding their leaves upward at night — are officially listed as non-toxic to cats by the ASPCA. Their stunning leaf patterns, variety of colors, and cat-safe profile make them one of the most recommended houseplants for pet-friendly homes. This guide covers everything you need to know about keeping calathea safely alongside cats, including which varieties to consider, what to watch for, and how to help both your plants and your cat thrive.

Why Is Calathea Safe for Cats?

Calathea plants belong to the family Marantaceae, commonly known as the prayer plant or arrowroot family. Unlike many popular houseplants that contain calcium oxalate crystals, toxic alkaloids, or irritating saps, calathea does not produce any compounds that are known to be harmful to cats.

The ASPCA’s animal poison control database lists multiple calathea species — including Calathea insignis (rattlesnake plant), Calathea lancifolia, Calathea orbifolia, and Calathea medallion — as non-toxic to cats, dogs, and horses. Many calathea species have been reclassified by botanists under the genus Goeppertia, but the common name “calathea” remains widely used in the houseplant world, and the safety classification has not changed.

Other members of the Marantaceae family, including Maranta (the true prayer plant), Stromanthe, and Ctenanthe, are also considered non-toxic to cats. This makes the entire prayer plant family one of the safest groups of houseplants for cat-friendly homes.

It is important to note that “non-toxic” does not mean “designed to be eaten.” If your cat regularly munches on calathea leaves, the plant fiber could still cause mild stomach upset — not from toxicity, but simply because cats are obligate carnivores and their digestive systems are not built to process large amounts of plant material. The key distinction is that calathea will not poison your cat, even if a curious nibble occurs.

Best Calathea Varieties for Cat-Friendly Homes

Calathea comes in dozens of species and cultivars, each with its own distinctive leaf pattern and personality. Here are some of the most popular and widely available varieties, all of which are safe for cats.

• Calathea orbifolia — features large, round leaves with elegant silver-green stripes; one of the most visually striking calatheas available
• Calathea medallion — dark green leaves with a central medallion-like pattern in lighter green and pink; a compact, versatile variety
• Calathea lancifolia (rattlesnake plant) — long, narrow leaves with alternating dark and light green markings that resemble rattlesnake skin; tolerates a wider range of conditions than some calatheas
• Calathea roseopicta (rose-painted calathea) — dramatic dark leaves with vibrant pink or cream striping; available in cultivars like Dottie, Rosy, and Medallion
• Calathea makoyana (peacock plant) — translucent, patterned leaves that look like stained glass when backlit; a true showstopper
• Calathea rufibarba (velvet calathea) — long, wavy leaves with a velvety texture on the underside; more forgiving than some other species
• Calathea zebrina (zebra plant) — bold, striped leaves with a velvety feel; a classic choice that pairs well with modern interiors
• Calathea white fusion — variegated leaves in white, green, and lilac; one of the most sought-after and challenging varieties to grow, but absolutely stunning

All of these varieties are non-toxic to cats. When choosing a calathea, consider your home’s light and humidity conditions alongside your aesthetic preferences, as some species are more demanding than others in terms of care requirements.

What Happens If Your Cat Eats Calathea?

Because calathea is non-toxic, there is no reason to panic if your cat takes a bite. However, here is what you might observe and how to handle it.

A cat that nibbles on a calathea leaf may experience mild gastrointestinal discomfort simply from eating plant fiber. This could manifest as a brief episode of vomiting or loose stool. These symptoms are not caused by toxins and typically resolve on their own within a few hours without any treatment.

If your cat vomits once after eating a small amount of calathea and then returns to normal behavior — eating, drinking, playing, and using the litter box as usual — there is generally no cause for concern. However, if vomiting persists, your cat refuses food or water for more than 12 hours, or you notice lethargy or other unusual behavior, contact your veterinarian. These symptoms would be unrelated to calathea toxicity but could indicate a gastrointestinal issue or a different underlying condition worth investigating.

The bigger concern with a cat that regularly chews on calathea is damage to the plant itself. Calathea leaves are delicate, and even minor chewing can leave unsightly marks. If your cat has developed a habit of snacking on your calathea, consider the prevention strategies below.

How to Prevent Your Cat from Chewing on Calathea

Even though calathea is safe, most plant owners would prefer their cats not treat their houseplants as salad bars. Here are practical strategies to discourage plant chewing.

• Provide cat grass. Growing a pot of cat grass (wheatgrass, oat grass, or barley grass) gives your cat a dedicated, safe plant to chew on and often reduces interest in other houseplants.
• Use placement strategically. While calathea is non-toxic, placing it on a high shelf, in a hanging planter, or behind a piece of furniture can reduce casual access and protect both plant and cat from unwanted interactions.
• Increase environmental enrichment. Cats often chew on plants out of boredom. Interactive toys, puzzle feeders, scratching posts, climbing trees, and regular play sessions can redirect that energy.
• Try a taste deterrent. Spraying calathea leaves with a pet-safe bitter apple spray can discourage chewing. Reapply regularly, especially after watering or misting.
• Offer variety. Rotating toys and introducing new enrichment activities can keep your cat’s curiosity satisfied without involving your houseplants.

Care Tips for Calathea in Cat-Friendly Homes

Calathea plants have a reputation for being somewhat fussy, but understanding their needs can help you succeed. Here are care tips tailored for homes with cats.

• Light: Calathea thrives in medium to bright indirect light. Avoid direct sunlight, which can scorch the leaves. A north-facing or east-facing window is often ideal.
• Humidity: Calathea loves humidity — ideally 50 percent or higher. Grouping plants together, using a pebble tray, or running a humidifier nearby can help. Avoid misting directly onto leaves if you use pest deterrent sprays.
• Watering: Keep the soil consistently moist but not waterlogged. Calathea is sensitive to minerals and chemicals in tap water; using filtered, distilled, or rainwater can prevent brown leaf tips.
• Soil: Use a well-draining potting mix that retains some moisture — a blend of peat, perlite, and orchid bark works well.
• Fertilizer: Feed with a diluted, balanced liquid fertilizer during the growing season (spring and summer). Keep fertilizer granules away from the soil surface if your cat investigates the pot — while calathea itself is safe, some fertilizers are not.
• Pot safety: Choose heavy, stable pots that your cat cannot easily knock over. If your cat likes to dig in soil, consider covering the soil surface with decorative stones or a piece of screen.

Other Cat-Safe Plants to Pair with Calathea

If calathea has inspired you to build a cat-safe indoor jungle, here are other non-toxic plants that pair beautifully with calathea.

• Boston fern — lush, cascading fronds that complement calathea’s bold patterns. See our guide on whether Boston fern is safe for cats.
• Spider plant — easy to grow, tolerant of neglect, and non-toxic to cats
• Areca palm — adds height and tropical flair alongside calathea’s low-to-medium profile
• African violet — compact, colorful flowers that are safe for cats
• Peperomia — varied leaf shapes and textures, all non-toxic to cats
• Polka dot plant (Hypoestes) — colorful spotted foliage that pairs well with calathea’s patterns
• Maranta (prayer plant) — a close relative of calathea with similar leaf movement behavior and an equally safe profile
• Cast iron plant (Aspidistra) — nearly indestructible and cat-safe, great for low-light corners

Building a collection of verified non-toxic plants is one of the most rewarding ways to enjoy indoor gardening alongside your cat. Always verify each new plant against the ASPCA’s toxic plant list before bringing it home.

Frequently Asked Questions

Is calathea safe for cats according to the ASPCA?

Yes. The ASPCA lists calathea as non-toxic to cats, dogs, and horses. This applies to all commonly grown calathea species and cultivars, including those now reclassified under the genus Goeppertia. You can verify this on the ASPCA’s searchable toxic and non-toxic plant database.

My cat ate a calathea leaf and vomited — should I be worried?

Occasional vomiting after eating non-toxic plant material is not uncommon in cats and is usually nothing to worry about. Cats are obligate carnivores, and their stomachs are not designed to process plant fiber. A single episode of vomiting followed by a return to normal behavior typically requires no treatment. If vomiting continues, your cat seems lethargic, or they stop eating or drinking, contact your veterinarian to rule out unrelated causes.

Are all plants in the prayer plant family safe for cats?

Yes. The Marantaceae family — which includes Calathea (Goeppertia), Maranta, Stromanthe, and Ctenanthe — is considered non-toxic to cats across the board. This makes the prayer plant family one of the best plant families for cat owners to explore when building a pet-safe houseplant collection.

Can I use fertilizer on calathea in a home with cats?

Yes, but take precautions. While calathea itself is non-toxic, some fertilizers contain ingredients that can be harmful to cats if ingested. Use liquid fertilizer diluted in water rather than granular fertilizer sprinkled on the soil surface, which a curious cat might lick or eat. If you use slow-release pellets, cover the soil surface with decorative stones or a screen to prevent access.

Is calathea safe for kittens as well as adult cats?

Yes. Calathea is non-toxic to cats of all ages, including kittens. Kittens are often more curious and more prone to chewing on plants than adult cats, so you may want to take extra precautions to limit access during the kitten phase — not because of safety concerns, but to protect the plant from enthusiastic nibbling and to prevent your kitten from developing a plant-chewing habit.
