Spider plants are among the most popular indoor greenery choices for pet owners, thanks to their lush, arching leaves and easy care. But if you’re a cat parent, you’ve likely caught your curious feline chewing on those tempting, dangly fronds. This often raises a critical question: Are spider plants harmful to cats? While they’re not classified as toxic, that doesn’t mean they’re risk-free for your furry friend. Understanding how spider plants interact with cats—and how to manage your home accordingly—can help keep both your plants and pets safe.

In this guide, we’ll cover everything you need to know about spider plants and their effects on cats, including why your kitty is so fascinated by them, what to do if they eat one, and safer plant alternatives that satisfy feline curiosity.

Are Spider Plants Toxic to Cats?

this idea

Good news for cat lovers—spider plants (Chlorophytum comosum) are classified as non-toxic to cats by the ASPCA. That means if your curious kitty takes a nibble, you likely won’t need to rush to the vet. However, non-toxic doesn’t mean harmless. While spider plants won’t poison your pet, they can still cause mild health issues if eaten in large amounts.

Cats aren’t built to digest houseplants efficiently. So even though spider plants aren’t chemically dangerous, excessive consumption can irritate a cat’s digestive system. Some cats may experience vomiting, upset stomach, or loose stools after eating spider plant leaves. These symptoms are typically short-lived but can still be uncomfortable for your pet.

If you suspect your cat has eaten part of a spider plant, monitor them for signs of distress. And if you have multiple plants in your home, it’s wise to make sure your cat didn’t nibble something truly toxic. When in doubt, consult your veterinarian—especially if your cat is showing symptoms that persist or worsen.

What Happens When a Cat Eats a Spider Plant?

When a cat munches on spider plants, the outcome usually depends on how much they’ve eaten. A small nibble may go unnoticed, but larger quantities can lead to gastrointestinal upset, especially in sensitive cats. Common signs include:

• Mild vomiting
• Diarrhea
• Lethargy
• Drooling
• Reduced appetite for a short time

While these symptoms may be mild and temporary, it’s important not to ignore them. Keep an eye on your cat for the next 24 hours. If vomiting persists, or your cat appears unusually lethargic or refuses food altogether, a vet visit is warranted—especially if there’s any chance they’ve also ingested a toxic plant nearby.

A Note on Psychedelic Effects

Some sources suggest that spider plants contain compounds with mild hallucinogenic effects for cats—similar to catnip. This might explain the excited or playful behavior some cats display around the plant. While this hasn’t been studied in depth, it’s another reason to limit how much access your cat has to the plant.

Why Do Cats Like Spider Plants?

If your cat seems obsessed with spider plants, you’re not alone. Many cats are irresistibly drawn to their long, arching leaves and dangling offshoots. There are a few likely reasons why this happens:

1. Visual and Physical Appeal

Spider plants naturally produce long, ribbon-like leaves and “pups” that hang off the main plant. To a cat, these resemble toys—making them perfect for swatting, pawing, and biting. The motion and shape mimic prey or play items, triggering your cat’s hunting instincts.

2. Sensory Stimulation

Some theories suggest spider plants may contain mild chemical compounds that produce a euphoric or stimulating effect in cats—similar to the response they have to catnip. While not scientifically proven, anecdotal evidence supports this idea.

3. Boredom or Lack of Greens

Indoor cats, especially those without access to fresh grass, often chew plants to fulfill their natural grazing instinct. If your cat doesn’t have alternatives like cat grass, they may turn to houseplants—including your spider plant.

Understanding why your cat is drawn to spider plants can help you redirect their attention and protect both your plants and their health.

How to Prevent Your Cat From Eating Your Spider Plant

While spider plants are not toxic to cats, it’s still best to keep them out of reach—both for your cat’s digestion and your plant’s survival. Cats can easily turn this houseplant into a chew toy, damaging the leaves and creating messes. Fortunately, a few simple strategies can help protect both.

1. Hang Your Spider Plant

One of the most effective methods is to place your spider plant in a hanging planter, suspended from the ceiling or a high hook. Keep it well away from furniture or shelves that your cat could use to launch a sneak attack.

2. Redirect Their Attention

Give your cat an appropriate alternative. Toys that dangle or sway, such as feather wands or interactive cat trees with hanging pieces, can fulfill the same sensory cravings. Rotating toys regularly can also help keep your cat mentally engaged.

3. Use Safe Deterrents

You can lightly mist the plant’s pot or surrounding area with cat-safe deterrent sprays (citrus-based sprays often work well). Be careful never to apply anything directly to the plant leaves that might harm your cat.

4. Offer Edible Greens

Provide a pot of cat grass or catnip nearby. These satisfy your cat’s urge to chew without risking their stomach. When cats have designated greens, they’re often less interested in the rest of your houseplants.

Keeping your spider plant safe doesn’t mean giving up greenery altogether—it just takes a bit of strategic placement and smart alternatives.

Best Plants for Cats to Nibble

If your cat loves chewing on your spider plants, offering them safe, cat-friendly alternatives can help redirect that behavior. Fortunately, several plants are not only safe for feline snacking but can actually support your cat’s natural instincts and digestive health.

1. Cat Grass (Wheatgrass)

One of the easiest and most popular options, cat grass is a mix of oat, wheat, barley, or rye grasses. It’s safe to eat, helps with hairball control, and satisfies your cat’s urge to graze.

2. Catnip (Nepeta cataria)

Known for its euphoric effect on cats, catnip is non-toxic and can be grown indoors in small pots. Just be prepared for zoomies or rolling behavior after they indulge.

3. Valerian (Valeriana officinalis)

Some cats respond positively to valerian, which can stimulate play and reduce stress. It’s safe for cats in moderate amounts and easy to grow.

4. Lemongrass

Lemongrass is generally safe for cats in small quantities and offers a strong scent that many cats enjoy. Just be cautious—too much can cause stomach upset.

5. Chamomile

While some chamomile types should be avoided, German chamomile (Matricaria recutita) is considered safer and can be calming for both cats and humans when consumed in moderation.

Offering these alternatives not only keeps your spider plants intact but gives your feline a healthy outlet for their natural behaviors.

Other Houseplants That Are Safe for Cats

If you’re building a pet-friendly indoor jungle, there are plenty of houseplants that pose no threat to your curious feline. While spider plants remain a top pick, here are other cat-safe plants to consider that add beauty without worry:

1. African Violet (Saintpaulia)

These charming, low-maintenance bloomers thrive in indirect light and are completely non-toxic to cats. Their soft leaves and colorful flowers make them a lovely choice for shelves or windowsills.

2. Boston Fern (Nephrolepis exaltata)

A classic houseplant with lush, feathery fronds, Boston ferns are safe for cats and add texture to any room. Just keep them in humid areas and out of direct sun.

3. Chinese Money Plant (Pilea peperomioides)

With its quirky, coin-shaped leaves, this trendy plant is both eye-catching and non-toxic to cats. It’s also easy to propagate and care for.

4. Prayer Plant (Maranta leuconeura)

Known for its striking, patterned leaves that “fold” at night, the prayer plant is cat-safe and thrives in low-light spaces.

5. Haworthia

This succulent is a perfect pet-friendly alternative to aloe. It’s compact, hardy, and non-toxic—ideal for sunny windowsills without the risk.

6. Bromeliads

These tropical beauties come in a variety of shapes and colors and are safe for cats. They do well in bright, humid spaces like kitchens and bathrooms.

7. Orchids (Orchidaceae)

Surprisingly, many orchids are non-toxic to cats and safe to grow indoors. They add a touch of elegance and bloom beautifully with the right care.

Adding these plants to your home lets you enjoy greenery while keeping your cat’s safety top of mind.

Plants That Are Toxic to Cats

While spider plants are generally safe, many common houseplants can be harmful—or even deadly—to cats if ingested. It’s important to know which plants to avoid so you can protect your feline friend from accidental poisoning.

Here’s a list of popular but toxic houseplants you should never keep around cats:

1. Aloe Vera

Though known for its healing properties for humans, aloe vera contains saponins that can cause vomiting, diarrhea, and lethargy in cats.

2. Pothos (Epipremnum aureum)

Also called Devil’s Ivy, pothos is toxic to cats and can lead to oral irritation, vomiting, and difficulty swallowing.

3. Snake Plant (Dracaena trifasciata)

This trendy plant contains compounds that can cause nausea and gastrointestinal upset in cats when chewed.

4. Alocasia (Elephant’s Ear)

Highly toxic to cats, ingestion can lead to severe oral pain, swelling, and even breathing difficulties.

5. Sago Palm (Cycas revoluta)

Extremely poisonous—even small amounts can cause liver failure. This plant is dangerous and should be avoided entirely in pet households.

6. English Ivy (Hedera helix)

This fast-growing climber contains triterpenoid saponins that cause drooling, vomiting, and abdominal pain.

7. Tulips and Daffodils

Popular in floral arrangements, these bulbs contain toxins that can trigger serious symptoms like heart irregularities or seizures if eaten.

8. Poinsettias

While often considered mildly toxic, poinsettias can still cause skin irritation and digestive upset if ingested.

If you suspect your cat has chewed on any of these toxic plants, contact your veterinarian or a pet poison helpline immediately. Keep the plant name and, if possible, a photo or sample to help identify the issue quickly.

Conclusion

Spider plants are a favorite among houseplant enthusiasts—and thankfully, they’re also one of the safer options for cat owners. While not toxic, they can still cause mild digestive upset if your feline friend treats them like a snack. Understanding why cats are attracted to spider plants and offering safer alternatives like cat grass or catnip can protect both your greenery and your pet’s health.

Creating a home that’s beautiful and cat-friendly doesn’t mean sacrificing your love of plants. With the right choices—and a little awareness—you can build an indoor oasis that keeps everyone happy, paws and all.
