Pet-Safe Houseplants: 35 Non-Toxic Indoor Plants Verified Safe for Dogs and Cats by the ASPCA
ASPCA-verified guide to pet-safe houseplants for cats and dogs. Full toxicity reference table, the 15 best non-toxic indoor plants, and which popular houseplants to avoid.
The ASPCA Animal Poison Control Center lists over 400 plants that are toxic to cats and dogs. Many of them — peace lily, pothos, dieffenbachia, rubber plant — sit in millions of American homes, looking innocent on bookshelves and windowsills. If your cat chews the leaves or your dog knocks a pot over and sniffs the soil, you could be dialing a veterinary emergency line within the hour.
The good news: you don’t have to live in a plant-free home. Dozens of genuinely beautiful, easy-care houseplants are completely non-toxic to cats and dogs, and this guide gives you a comprehensive, ASPCA-verified reference to choose the right ones. You’ll also find a full diagnostic table covering 22 common species, and a clear breakdown of which popular plants should be removed or relocated when you share your home with pets.
How ASPCA Classifies Plant Toxicity
The ASPCA Animal Poison Control Center (APCC) maintains the most comprehensive plant toxicity database in North America, drawing on clinical case records, veterinary toxicology literature, and plant chemistry research. Their classifications are specific to cats and dogs — assessed separately for each species — and cover three broad risk levels:
- Non-toxic: No known toxic principle. Ingestion is not expected to cause systemic harm. Minor gastrointestinal upset can occur from eating any fibrous foreign material, but this is a mechanical response, not a toxicity reaction.
- Mildly toxic: Contains compounds that cause localized or transient effects — most commonly drooling, vomiting, or diarrhea. Uncomfortable but rarely life-threatening with prompt care.
- Moderately to severely toxic: Contains compounds capable of causing cardiac arrhythmias, kidney failure, neurological effects, or death. Requires immediate veterinary attention.
An important nuance: non-toxic does not mean consequence-free. A kitten that eats an entire spider plant may vomit because plant fiber upsets any stomach — not because the plant contains a recognized toxin. The ASPCA classification addresses whether a plant contains compounds with known systemic toxicity, not whether consuming large quantities of any vegetation is advisable.
When in doubt, call the ASPCA Animal Poison Control Center at (888) 426-4435. A consultation fee applies, but it’s staffed around the clock by board-certified veterinary toxicologists. For the most current species-level list, the authoritative reference is the ASPCA Toxic and Non-Toxic Plants database, searchable by common and Latin name.
The 15 Best Pet-Safe Houseplants
Each of the following plants is classified as non-toxic to both cats and dogs by the ASPCA. They range from dramatic statement pieces to compact flowering plants — there’s no need to compromise on style for safety.
1. Spider Plant (Chlorophytum comosum)
One of the most forgiving and adaptable houseplants in existence, the spider plant is also one of the most thoroughly studied for pet safety. ASPCA lists it as non-toxic to both cats and dogs. Note: cats are sometimes attracted to spider plants because of mild hallucinogenic compounds similar to catnip — this can cause vomiting if eaten in excess, but there’s no systemic toxicity. Spider plants thrive in indirect light and tolerate irregular watering, making them ideal for busy households.
2. Calathea and Prayer Plants (Calathea spp., Maranta leuconeura)
The calathea family — including rattlesnake plants, peacock plants, and prayer plants — is completely non-toxic to cats and dogs. These plants are prized for their extraordinary foliage: deep greens, purples, and cream-white markings that make them some of the most visually striking choices for any indoor collection. They prefer medium to low indirect light and consistent moisture, making them a go-to for pet-safe indoor displays in rooms that other plants find too dim.
3. Boston Fern (Nephrolepis exaltata)
Boston ferns are lush, full-bodied, and reliably non-toxic to both cats and dogs. Their arching fronds make them excellent choices for hanging baskets — which doubles as a practical strategy for keeping curious paws at a safe distance. They prefer humid environments and indirect light; a bathroom with a window or a sunlit kitchen suits them well. Mist regularly or set on a pebble tray with water to maintain humidity, especially during winter months when central heating dries the air.
4. African Violet (Saintpaulia ionantha)
African violets are compact, flower prolifically throughout the year, and are safe for both cats and dogs. They bring color to north- or east-facing windowsills that many houseplants find too dim to thrive in. Water from below — pour into the saucer and let the plant absorb upward — to prevent leaf spotting. Available in purple, pink, white, and bicolor varieties, they’re among the most reliably blooming pet-safe options available.
5. Parlor Palm (Chamaedorea elegans)
Parlor palms are the compact palm of choice for households with pets. Non-toxic to both cats and dogs, they grow slowly to three or four feet, tolerate low light remarkably well, and have none of the sharp spines of larger palms. They prefer consistently moist (but not waterlogged) soil and do well in indirect light. An excellent choice for living rooms and bedrooms where you want a tropical feel without a safety risk.
6. Areca Palm (Dypsis lutescens)
For a larger tropical statement, the areca palm delivers dramatic height — often reaching six feet indoors — without toxicity risk. ASPCA classifies it as non-toxic to both cats and dogs. Areca palms prefer bright indirect light and slightly drier conditions between waterings than parlor palms. They’re frequently used as natural room dividers in open-plan spaces, making them one of the few genuinely safe large-scale houseplants for pet owners.
7. Orchid (Phalaenopsis and most genera)
Phalaenopsis orchids — the moth orchids sold at supermarkets and garden centers — are non-toxic to cats and dogs. Most other common orchid genera are similarly safe, though the ASPCA recommends checking individual species for rare exceptions. Orchids rebloom reliably when kept in bright indirect light with cool nights, making them a long-lasting, elegant, and genuinely safe centerpiece choice.
8. Peperomia
The peperomia genus spans hundreds of species, from the coin-leafed Peperomia polybotrya to the deeply ridged Peperomia caperata. ASPCA classifies peperomias as non-toxic to both cats and dogs. Their compact size, interesting textures, and tolerance for lower light and irregular watering make them ideal for shelves, desks, and countertops in pet-heavy households.
9. Bromeliad (Bromeliaceae family)
Bromeliads — including Guzmania, Vriesea, and Neoregelia — are non-toxic houseplants that produce vivid, long-lasting floral spikes and striking foliage rosettes. They thrive in bright indirect light and are watered by filling the central cup formed by their leaves. After flowering, they produce pup offshoots that can be separated and grown on — a single plant becomes a collection over time, all of it safe.
10. Money Tree (Pachira aquatica)
The money tree is a popular feng shui plant with a braided trunk, palm-like leaves, and good safety credentials: ASPCA lists it as non-toxic to dogs and cats. Money trees prefer bright indirect light and weekly watering, allowing the top inch of soil to dry between waterings. Frequently sold as gifts, they make excellent centerpiece plants on dining tables or sideboards and are safe in any room of the home.
11. Haworthia
Often mistaken for aloe — which is toxic to cats and dogs — haworthias are a completely safe succulent alternative. ASPCA classifies haworthias as non-toxic to both species. They’re compact, slow-growing, and extremely drought-tolerant, making them ideal for windowsills where pets sunbathe. The key identification difference from aloe: haworthia leaves are typically harder and more pointed, often with distinctive white stripes or raised bumps.
12. Air Plant (Tillandsia)
Air plants are non-toxic to cats and dogs, and their growing habit — mounted on driftwood, hung in glass globes, or displayed on decorative holders — naturally places them out of reach of most pets. They absorb moisture and nutrients through their leaves, requiring only a weekly misting or a brief 20-minute soak. Low maintenance, space-efficient, and structurally safe, they’re among the easiest pet-friendly plants to incorporate into any display.
13. Swedish Ivy (Plectranthus australis)
Swedish ivy is a trailing plant well suited for hanging baskets, where its stems cascade downward out of a pet’s reach. ASPCA classifies it as non-toxic to cats and dogs. It grows in bright to medium indirect light and prefers slightly moist soil. Its soft, scalloped leaves and vigorous trailing habit make it a popular pet-safe substitute for pothos in kitchen shelves and bathroom displays.
14. Christmas Cactus (Schlumbergera spp.)
Christmas and Thanksgiving cacti are non-toxic to cats and dogs — an important distinction from many other succulents and cacti, some of which cause gastrointestinal irritation. Christmas cacti produce pendulous flowers in red, pink, orange, purple, and white during winter months and tolerate lower light than most succulents. They prefer cooler night temperatures to trigger blooming and make excellent holiday season plants for pet owners who want color without risk.
15. Cast Iron Plant (Aspidistra elatior)
The cast iron plant lives up to its name: it tolerates low light, irregular watering, wide temperature swings, and general neglect better than almost any other houseplant. ASPCA classifies it as non-toxic to cats and dogs. Its strap-like, deep-green leaves grow slowly to around two feet tall and require minimal care. For dark hallways, north-facing bedrooms, or rooms where other plants refuse to thrive, the cast iron plant is the reliable, pet-safe answer.

Toxic Houseplants to Avoid (and Safer Alternatives)
These are the most commonly owned houseplants that pose a risk to cats and dogs. Each entry links to a full care guide for readers who currently own the plant and need to decide whether to rehome it, relocate it out of reach, or replace it with a safe alternative.

→ Build Watering SchedulePeace Lily (Spathiphyllum) — Toxic to cats and dogs
The peace lily is one of the most popular houseplants in the US — and one of the most frequently reported causes of plant-related pet poisonings. It contains calcium oxalate crystals, insoluble compounds that cause immediate burning in the mouth and throat on contact. Symptoms include intense drooling, pawing at the mouth, vomiting, and difficulty swallowing. Severity depends on quantity ingested, but even small amounts cause significant distress and warrant a veterinary call. The peace lily’s shade tolerance and elegant white spathes are matched by parlor palm and African violet — both safe alternatives.
Pothos (Epipremnum aureum) — Toxic to cats and dogs
Pothos is the trailing plant found in almost every office, dorm room, and bright kitchen — cheap, fast-growing, and nearly unkillable. It’s also toxic to both cats and dogs via the same calcium oxalate mechanism as peace lily. The trailing stems and dangling leaves are particularly attractive to cats, making accidental ingestion more likely than with tabletop plants. Swedish ivy offers a nearly identical trailing growth habit and is completely non-toxic.
Safer alternative: Swedish ivy or Boston fern for cascading displays.
Dieffenbachia / Dumb Cane (Dieffenbachia) — Toxic to cats and dogs
Dieffenbachia earns its common name from its most infamous effect: the calcium oxalate crystals and proteolytic enzymes it contains cause such intense oral burning that the plant has been known to cause temporary speech loss in humans — and significant throat swelling in pets. In severe cases, ingestion can interfere with breathing. This is among the higher-severity plants on this list and should be fully removed from pet households, not merely elevated out of reach.
Safer alternative: Calathea or peperomia for bold tropical foliage.
Jade Plant (Crassula ovata) — Toxic to cats and dogs
The jade plant is a long-lived, low-maintenance succulent — but its exact toxic mechanism remains unidentified, which makes predicting severity difficult. Symptoms include vomiting, lethargy, incoordination, and depression, with cats appearing more susceptible than dogs. The thick, fleshy leaves may attract chewing more than slimmer-leafed plants. Haworthia looks visually similar, is equally low-maintenance, and is completely non-toxic.
Safer alternative: Haworthia for a compact, architectural succulent.
Bird of Paradise (Strelitzia) — Toxic to cats and dogs
The bird of paradise is among the more mildly toxic plants on this list — symptoms from tannins are typically limited to nausea, mild vomiting, and drowsiness. However, “mild” is relative: a 10-pound cat vomiting repeatedly still warrants a veterinary call. For households with large, well-trained dogs, the risk with a secured high placement may be manageable. For cat households, consider replacing with areca or parlor palm for the same dramatic tropical height.
Safer alternative: Areca palm or parlor palm for tall tropical statement plants.
Rubber Plant (Ficus elastica) — Toxic to cats and dogs
The rubber plant secretes a milky latex when cut or damaged — this latex contains ficin (a proteolytic enzyme) and psoralen, which cause GI irritation, skin sensitization, and eye irritation. It’s worth noting that the entire Ficus genus shares this concern, including weeping fig (F. benjamina) and fiddle-leaf fig (F. lyrata). Money tree delivers a similarly bold-leafed tropical statement and is safe for both cats and dogs.
Safer alternative: Money tree for a bold-leafed tropical that’s genuinely pet-safe.
Snake Plant (Dracaena trifasciata) — Toxic to cats and dogs
Despite appearing in countless “safe houseplant” roundups across the internet, the snake plant is classified as toxic to cats and dogs by the ASPCA. The active compounds are saponins, which cause nausea, vomiting, and diarrhea. Toxicity is generally mild compared to dieffenbachia or peace lily — serious harm is uncommon — but the misinformation around snake plants is so widespread that it’s worth stating clearly: if you have a cat or dog, the snake plant should be treated as a toxic plant. Cast iron plant delivers the same low-light, architectural appeal with zero toxicity risk.
Safer alternative: Cast iron plant for a low-light, architectural pet-safe option.
Displaying Plants Safely in Pet Households
Even with a collection made entirely of non-toxic plants, practical display strategies reduce the risk of upset stomachs, knocked-over pots, and soil scatter.
Elevate and hang
Hanging baskets are the most effective physical barrier between a plant and a curious cat or dog. Wall-mounted planters, floating shelves, and ceiling hooks put plants completely out of reach of dogs and above the jump zone for most cats. Boston ferns, spider plants, and Swedish ivy all grow beautifully in hanging configurations. For floor plants, use heavy ceramic or terracotta pots that resist tipping — lightweight plastic nursery pots invite chaos in active households.
Use deterrents strategically
Citrus scents deter most cats and dogs effectively. Placing dried citrus peel at the base of floor plants, or lightly misting pot rims with a diluted citrus essential oil solution (never directly on leaves), discourages approach. Commercial bitter sprays applied to accessible lower leaves work similarly. Double-sided tape around pot rims creates a texture barrier that many cats won’t cross. Rotate these deterrents periodically — animals learn to ignore static cues over time.
Separate by room access
For any plants with mild toxicity concerns, room separation is the most reliable long-term solution. A sunroom, home office, or bedroom with a closed door creates a pet-free plant zone with no ongoing management required. Baby gates with small cat access flaps allow you to control which rooms pets can enter — useful for maintaining a display room that your dog cannot reach while you’re not watching.
Emergency preparedness
Keep the ASPCA Animal Poison Control Center number saved: (888) 426-4435. A consultation fee applies, but the service is available 24 hours a day, staffed by board-certified veterinary toxicologists. Your primary vet’s emergency line should be the first call for severe symptoms. When you call, have the plant’s Latin name ready if possible — some common names apply to multiple unrelated species with very different toxicity profiles, and “green trailing plant” is not enough information for a toxicologist to work with.
Frequently Asked Questions
Is spider plant toxic to cats?
Spider plants are classified as non-toxic to cats by the ASPCA. However, cats are often attracted to spider plants because of mildly hallucinogenic compounds similar to catnip — this can trigger vomiting if eaten in quantity, but the vomiting is a mechanical GI response to fibrous material, not a toxicity reaction. You don’t need to remove spider plants from a cat household, but hanging them reduces the temptation to chew.
Are all ferns safe for cats and dogs?
No — and this is a critical distinction. Boston fern (Nephrolepis exaltata) and sword fern are non-toxic to cats and dogs. However, asparagus fern (Asparagus setaceus) — which resembles a fern but is a member of the lily family — is toxic to both species, causing GI effects and, with repeated skin contact, dermatitis. Autumn fern (Dryopteris erythrosora) is also toxic. Always verify by Latin name using the ASPCA database, not by common name alone.
Are succulents safe for cats and dogs?
It depends on the species. Haworthia and echeveria are non-toxic to both cats and dogs. Aloe vera — often sold alongside them as a group — is toxic to cats and dogs, causing vomiting, diarrhea, lethargy, and in larger quantities, tremors. Jade plant (Crassula ovata) is also toxic. The word “succulent” spans dozens of genera with widely varying toxicity profiles. Research each species individually using the ASPCA database before purchasing, and don’t rely on nursery labels or online lists that bundle all succulents together as safe.
What should I do if my pet eats a non-toxic plant?
Monitor for GI symptoms: vomiting, diarrhea, lethargy, or loss of appetite. These may occur simply because plant material is foreign to the digestive system. Most symptoms resolve within 12 to 24 hours without intervention. If symptoms persist, worsen, or are accompanied by neurological signs (stumbling, disorientation, dilated pupils), contact your veterinarian. Even with non-toxic plants, individual animals can have sensitivities — the ASPCA classification describes population-level safety, not absolute individual allergy risk.
Can I keep a toxic plant if I put it somewhere my pet can’t reach?
In theory, yes — in practice, this is harder to guarantee than it sounds, especially for cats. Dogs are generally controllable with height, but cats can access almost any surface in a home. The question isn’t whether you can place a plant somewhere currently unreachable — it’s whether you can guarantee it remains there permanently, including if it falls, is knocked over, or sheds leaves onto the floor. For high-toxicity plants like dieffenbachia, the risk-benefit calculation rarely favors keeping the plant in a pet household. For mildly toxic plants like bird of paradise, a secured high shelf may be a reasonable compromise in a dog-only home.
