Are Calathea Safe for Cats? Prayer Plant Pet Safety

Last updated: April 10, 2026

Are Calathea Plants Safe for Cats?

Yes, calathea plants — commonly known as prayer plants — are non-toxic to cats. According to the ASPCA, calathea species are safe for both cats and dogs, making them one of the best houseplant choices for pet-owning households. If your cat nibbles on a calathea leaf, you don’t need to rush to the veterinarian.

This is welcome news for cat owners who love houseplants but worry about the long list of common plants that are dangerous to felines. While many popular houseplants (including peace lilies, pothos, and dieffenbachia) contain compounds that can harm cats, calathea offers stunning foliage without the toxicity risk.

That said, “non-toxic” doesn’t mean “designed to be eaten.” While calathea won’t poison your cat, eating large amounts of any plant material can cause mild stomach upset. Let’s explore what makes calathea safe, which varieties are most popular, and how to keep both your plants and your cats happy.

Why Calathea Are Considered Pet-Safe

Calathea plants belong to the Marantaceae family, which also includes Maranta (the classic prayer plant) and Stromanthe — all of which are non-toxic to cats and dogs. Unlike plants such as peace lilies and dieffenbachia that contain calcium oxalate crystals, or pothos that contains toxic raphides, calathea plants do not produce compounds that are harmful to feline metabolism.

The ASPCA Poison Control Center lists calathea as non-toxic to cats, dogs, and horses. This classification means that ingestion of any part of the plant — leaves, stems, or roots — is not expected to cause poisoning symptoms.

However, cats that eat significant quantities of calathea leaves may experience mild gastrointestinal upset, including:

• Mild vomiting
• Soft stool or mild diarrhea
• Temporary decrease in appetite

These symptoms are caused by the plant fiber irritating the digestive tract, not by toxic compounds. They’re typically mild and self-limiting, resolving within a few hours without treatment. If symptoms persist beyond 24 hours or seem severe, consult your veterinarian to rule out other causes.

Popular Calathea Varieties for Cat-Friendly Homes

Calathea come in dozens of stunning varieties, each with unique leaf patterns and colors. Here are some of the most popular options that are safe to keep around your cats:

Calathea Orbifolia

One of the most striking varieties, Calathea orbifolia features large, round leaves with silvery-green stripes. It’s a statement plant that looks dramatic in a living room or bedroom. Its broad leaves may attract curious cats, but rest assured — it’s completely safe.

Calathea Medallion

The Medallion variety has round leaves with elaborate dark green patterns on top and rich purple undersides. It’s one of the most widely available calathea and an excellent entry point for new plant owners.

Calathea Lancifolia (Rattlesnake Plant)

Named for its long, lance-shaped leaves with alternating dark and light green spots, the Rattlesnake Plant is both eye-catching and easy to care for. Its narrow leaves are less tempting to cats than broader varieties.

Calathea Makoyana (Peacock Plant)

With translucent leaves patterned in shades of green and cream, the Peacock Plant is a favorite among collectors. It thrives in the same humid, low-light conditions that many homes provide.

Calathea Roseopicta (Rose-Painted Calathea)

Available in several cultivars (including ‘Dottie’ with nearly black leaves and pink outlines), this variety adds dramatic color to any space. All Roseopicta varieties are cat-safe.

All of these varieties share the same pet-safe classification, so you can choose based on aesthetics and care requirements without worrying about toxicity.

Calathea Care Basics for Busy Pet Owners

Calathea have a reputation for being finicky, but with a few basics in place, they’re quite manageable. Here’s what they need to thrive in your pet-friendly home:

Light: Calathea prefer bright, indirect light. Direct sunlight will scorch their leaves, causing brown edges and faded patterns. A north-facing window or a spot a few feet from an east-facing window is ideal. Their tolerance for lower light makes them perfect for rooms that don’t get intense sun.

Water: Keep the soil consistently moist but not waterlogged. Calathea are sensitive to chemicals in tap water — if your tap water is heavily chlorinated or contains fluoride, let it sit out overnight before watering or use filtered water. Yellowing leaf edges are often a sign of water quality issues.

Humidity: This is where calathea can be demanding. They prefer humidity levels of 50% or higher. Brown, crispy leaf edges are the telltale sign of insufficient humidity. A pebble tray, humidifier, or grouping plants together can help. Bathrooms with natural light are often ideal calathea locations.

Temperature: Keep calathea in rooms between 65 and 80 degrees Fahrenheit. They dislike cold drafts and sudden temperature changes, so avoid placing them near exterior doors or heating/cooling vents.

Soil: A well-draining potting mix with peat moss, perlite, and orchid bark works well. Good drainage prevents root rot, which is the most common cause of calathea death.

How to Discourage Your Cat From Eating Plants

Even though calathea are safe, you may want to protect your plants from enthusiastic feline nibblers. Chewed leaves don’t grow back, and replacing damaged calathea can be expensive for rarer varieties.

Here are effective, cat-safe strategies:

• Provide cat grass: Offering wheat grass, oat grass, or barley grass gives your cat a sanctioned greens option. Many cats prefer cat grass over houseplants when given the choice.
• Use citrus deterrents: Cats generally dislike citrus scents. Placing orange or lemon peels around the base of your plants, or lightly misting leaves with a diluted citrus solution, can discourage nibbling.
• Elevate plants: Placing calathea on high shelves, in hanging planters, or on plant stands reduces access. Though determined cats can reach almost anything, elevation does reduce casual munching.
• Redirect with play: Cats often chew on plants out of boredom. Increasing interactive play time, providing puzzle feeders, and rotating toys can reduce plant-directed behavior.
• Try bitter apple spray: Applied to leaf edges, bitter apple spray makes the plant taste unpleasant without harming the cat or the plant. Reapply after watering.

A combination of these strategies usually keeps both your calathea and your cat content.

Other Pet-Safe Houseplants to Pair With Calathea

If calathea have inspired you to build a cat-safe plant collection, here are additional non-toxic houseplants that pair beautifully with prayer plants:

• Spider Plant (Chlorophytum comosum): Extremely easy to grow, tolerant of neglect, and completely non-toxic. Their dangling babies are tempting cat toys, so hang them high.
• Boston Fern (Nephrolepis exaltata): Lush, cascading fronds that love the same humidity as calathea. Non-toxic and stunning in a hanging basket.
• African Violet (Saintpaulia): Compact, flowering, and safe for cats. They enjoy similar indirect light conditions as calathea.
• Parlor Palm (Chamaedorea elegans): A graceful, low-light tolerant palm that’s safe for all pets. Adds a tropical feel without any toxicity risk.
• Peperomia (various species): Compact, varied, and entirely non-toxic. Their thick, waxy leaves are less appealing to cats than thinner foliage.
• Haworthia: A small succulent that’s safe for cats and nearly indestructible. Perfect for bright windowsills.

Calathea and the “Prayer Plant” Movement

One of calathea’s most charming features is their nyctinastic movement — the leaves fold upward at night, resembling hands in prayer, and unfurl again in the morning. This daily movement is driven by changes in light and is completely normal.

For cat owners, this movement has an unexpected benefit: it can fascinate cats. Many owners report that their cats watch the leaves move at dusk and dawn with rapt attention. It’s a form of enrichment that’s completely safe and endlessly entertaining.

If your calathea’s leaves stop moving, it may indicate stress from overwatering, underwatering, or insufficient light. A healthy calathea that “prays” every night is a happy calathea — and a happy addition to your cat-friendly home.

Frequently Asked Questions

Are all calathea varieties safe for cats?

Yes. All species and cultivars within the Calathea genus (now reclassified under Goeppertia by botanists, though still sold as Calathea) are non-toxic to cats. This includes Calathea orbifolia, medallion, lancifolia, makoyana, roseopicta, and all other common varieties.

My cat ate a lot of calathea leaves and is vomiting. Should I worry?

Mild vomiting after eating a large amount of any plant material is normal and usually resolves within a few hours. Offer fresh water and withhold food for a couple of hours to let the stomach settle. If vomiting persists beyond 24 hours, is bloody, or is accompanied by lethargy, contact your veterinarian to rule out other issues.

Are Maranta (prayer plants) also safe for cats?

Yes. Maranta, Stromanthe, and Ctenanthe — all close relatives of calathea in the Marantaceae family — are non-toxic to cats and dogs. The entire prayer plant family is pet-safe.

Can I use calathea to replace toxic plants in my home?

Absolutely. Calathea are excellent replacements for toxic plants that thrive in similar conditions. For example, calathea can replace dieffenbachia or peace lilies in low-to-medium light spots. The variety of calathea available means you can find options that match nearly any aesthetic preference.

Do calathea need any special care that might affect my cat?

Calathea benefit from occasional misting or humidity trays, which don’t pose any risk to cats. The only consideration is fertilizer — if you use liquid fertilizer, ensure your cat doesn’t drink water that drains from the pot, as fertilizer can cause stomach upset. Using a saucer and emptying it promptly after watering eliminates this minor risk.
