Every plant parent with pets faces the same worry: which houseplants won’t harm their cat or dog if curiosity gets the better of them? We’ve reviewed the major toxicity databases and veterinary guidance to build this complete reference — covering 20 safe options, the plants you must avoid, and exactly what to do if your pet takes a bite.
Why Plant Toxicity Matters
Most houseplant poisonings in pets are accidental. A cat bats at a dangling leaf and swallows it. A dog digs in a pot and chews a root. The severity ranges from mild stomach upset to organ failure — and in some cases, death within days.
The risk isn’t theoretical. Lilies, for example, cause acute kidney failure in cats. Every part of the plant — petals, leaves, pollen, even the water in the vase — contains nephrotoxic compounds. There is no safe dose. Sago palms are equally devastating to dogs: ingestion of just a few seeds can lead to liver necrosis and death.
Symptoms of plant poisoning vary by toxin but commonly include drooling, vomiting, diarrhoea, lethargy, difficulty breathing, and seizures. The onset can be immediate or delayed up to 72 hours, which makes prompt action critical even if your pet seems fine initially.
This guide uses classifications from the ASPCA, RSPCA, and Pet Poison Helpline. We cross-reference their databases against practical care considerations to give you a list you can trust — and keep in your home with confidence.
Top 20 Pet-Safe Houseplants
These plants appear on all major non-toxic lists and tolerate typical indoor conditions. We’ve grouped them by care difficulty so you can match them to your experience level.
Easy Care (Neglect-Tolerant)
Spider Plant (Chlorophytum comosum) — Arching green-and-white striped leaves with baby plantlets that dangle like ornaments. Tolerates low light, inconsistent watering, and average humidity. Non-toxic to both cats and dogs. If your cat chews the leaves, expect mild stomach upset at worst — no veterinary intervention needed.
Boston Fern (Nephrolepis exaltata) — Lush, feathery fronds that thrive in indirect light and high humidity. Safe for all pets. The only risk is soil ingestion if your dog digs, so use a top layer of pebbles if needed.
Parlor Palm (Chamaedorea elegans) — A Victorian favourite that survives in dim corners and forgives missed waterings. Slow-growing and entirely non-toxic. Its fronds are too tough for most cats to bother with, which reduces temptation.
Cast Iron Plant (Aspidistra elatior) — Practically indestructible. Dark green, broad leaves tolerate deep shade, dry air, and irregular watering. Zero toxicity concerns for pets.
Areca Palm (Dypsis lutescens) — Feather-like fronds create a tropical feel. Loves bright, indirect light and consistent moisture. Non-toxic and unlikely to attract chewing due to its fibrous texture.
Money Tree (Pachira aquatica) — Braided trunk, glossy hand-shaped leaves, and a reputation for bringing luck. Thrives in bright indirect light with weekly watering. The RSPCA and ASPCA both list it as non-toxic to cats and dogs.
Moderate Care (Some Attention Needed)
Calathea (Goeppertia spp.) — Dramatic patterned leaves that fold up at night. Needs consistent humidity above 50% and distilled or rainwater to prevent brown tips. Entirely safe for pets, though cats may find the moving leaves fascinating.
Peperomia (Peperomia spp.) — Compact, succulent-like leaves in endless varieties: watermelon, ripple, obtusifolia. Pet-safe and perfect for shelves where cats roam. Water when the top inch of soil dries.
African Violet (Saintpaulia ionantha) — Velvety leaves and year-round flowers in purple, pink, or white. Needs bright indirect light and careful watering — wet leaves spot easily. Non-toxic to all pets.
Orchid (Phalaenopsis spp.) — Elegant arching stems with long-lasting blooms. Safe for cats and dogs. The flowers are non-toxic but may cause mild stomach upset if eaten in quantity. Place on a high shelf to protect the blooms from batting paws.
Polka Dot Plant (Hypoestes phyllostachya) — Speckled pink, red, or white foliage adds colour without flowers. Needs bright light to maintain its pattern. Non-toxic, though not particularly interesting to pets.
Bird’s Nest Fern (Asplenium nidus) — Wavy, bright green fronds emerging from a central rosette. Loves humidity and indirect light. Safe for all pets and visually striking enough to earn a spot in any room.
Advanced Care (Enthusiasts Only)
Staghorn Fern (Platycerium bifurcatum) — Antler-shaped fronds that grow mounted on wood. Requires regular misting and indirect light. Non-toxic but best kept out of reach since the mounting setup isn’t sturdy against climbing cats.
Baby Tears (Soleirolia soleirolii) — Dense, delicate ground cover with tiny leaves. Needs consistently moist soil and bright indirect light. Safe for pets, though its trailing habit invites investigation.
Friendship Plant (Pilea involucrata) — Quilted, bronze-green leaves with a textured surface. Loves humidity and indirect light. Non-toxic and compact enough for terrariums.
Lipstick Plant (Aeschynanthus radicans) —Trailing stems with tubular red flowers. Bright indirect light and regular watering keep it blooming. Safe for pets.
Hoya (Hoya spp.) — Waxy, succulent-like leaves and clusters of star-shaped flowers. Slow-growing and long-lived. Non-toxic, though the waxy leaves don’t appeal to most pets.
Rattlesnake Plant (Goeppertia insignis) — Elongated leaves with dark green spots and purple undersides. Another prayer plant relative that’s entirely pet-safe. Needs humidity and filtered light.
Mosaic Plant (Fittonia albivenis) — Veined leaves in electric pink, red, or white. Dramatic but dramatic: it wilts dramatically when thirsty, then perks up within hours of watering. Non-toxic to all pets.
Watermelon Peperomia (Peperomia argyreia) — Silver-striped, oval leaves that look like watermelon rind. Compact and pet-safe. Allow soil to dry between waterings.
Cat-Safe Plant Details
Cats are obligate carnivores, but many chew grass and leaves to aid digestion or induce vomiting when they have hairballs. This instinct makes them more likely than dogs to nibble houseplants.
The safest strategy is providing an alternative. Cat grass (wheatgrass, oat grass, or barley grass) satisfies the urge to chew greenery and is sold in most pet shops. Place it near your cat’s favourite sunspot and redirect them when they approach other plants.
For the plants listed above, these are particularly cat-friendly:
Spider Plant — The dangling babies trigger prey drive, but ingestion is harmless. If your cat destroys the plantlets, trim them back.
Calathea — The leaf-folding behaviour fascinates cats. Place it where they can watch but not reach if they get too interested.
Boston Fern — The feathery texture appeals to cats, but it’s entirely safe. Just keep the soil covered if your cat digs.
Orchid — Non-toxic, but expensive to replace if your cat bats off the flowers. High placement is best.
Avoid placing any plant near litter boxes or feeding stations. Cats associate these areas with safety and may mark or dig in nearby soil.
Dog-Safe Plant Details
Dogs interact with plants differently than cats. They’re less likely to nibble leaves casually, but more likely to dig in pots, chew stems when bored, or drink from plant saucers.
The primary risk for dogs is soil and fertiliser ingestion. Many potting mixes contain cocoa shell mulch or bone meal — both attractive and potentially harmful to dogs. Use plain peat or coir-based compost and avoid fertilisers with blood, bone, or fish meal if your dog is a digger.
Top dog-safe choices from our list:
Parlor Palm — Tough, non-toxic, and uninteresting to chew. Its height keeps fronds above nose level.
Areca Palm — Creates a dense screen that’s safe if your dog brushes through it. The fibrous fronds don’t appeal to chewers.
Money Tree — The braided trunk withstands curious noses, and the ASPCA confirms its safety.
Cast Iron Plant — Extremely hardy. If your dog knocks the pot over, the plant survives and poses no toxicity risk.
For dogs that dig, use heavy ceramic pots, cover soil with large stones or mesh, and provide a designated digging area outdoors or a snuffle mat indoors to redirect the behaviour.
Certified Safe Lists
Several organisations maintain rigorously tested databases of plant toxicity. We cross-reference all our recommendations against these sources.
ASPCA Animal Poison Control (USA)
The ASPCA maintains the most comprehensive database, with over 1,000 plants classified as toxic or non-toxic to dogs, cats, and horses. Every plant in our safe list appears on their non-toxic register. The ASPCA also operates a 24-hour poison helpline for emergencies.
RSPCA (UK)
The RSPCA provides guidance tailored to UK pet owners, with a focus on plants commonly found in British homes and gardens. Their advice aligns closely with the ASPCA but includes additional warnings for plants more prevalent in the UK, such as certain spring bulb varieties.
Pet Poison Helpline
This veterinary-operated service classifies plants by severity and provides treatment protocols used by vets worldwide. Their database is particularly valuable for identifying the specific toxin in a plant and its mechanism of action.
International Cat Care
Formerly the Feline Advisory Bureau, this UK charity focuses specifically on cat welfare. Their plant safety guidance is conservative — they flag any plant that causes even mild symptoms, making their safe list particularly reliable for cautious owners.
When in doubt, search these databases by botanical name (the Latin name in parentheses throughout this guide). Common names vary by region, but the scientific name is universal.
Plants to Absolutely Avoid
These plants cause severe or fatal poisoning. Do not keep them in any home with pets, even on high shelves — pollen falls, leaves drop, and water spills.
Lilies (Lilium and Hemerocallis spp.) — Fatal to Cats
Every lily species is toxic to cats. Ingestion of any part — petal, leaf, stem, pollen, or vase water — causes acute kidney failure. Symptoms appear within 6-12 hours: vomiting, lethargy, loss of appetite. Without immediate veterinary treatment, death occurs within 3-7 days.
There is no safe lily for cats. This includes Easter lilies, tiger lilies, daylilies, stargazer lilies, and peace lilies (though peace lilies are less dangerous, they still cause significant oral irritation).
Sago Palm (Cycas revoluta) — Fatal to Dogs
The seeds are the most toxic part, but all parts contain cycasin, which causes liver failure. Symptoms include vomiting, diarrhoea, seizures, and jaundice. The mortality rate is high even with aggressive treatment.
ZZ Plant (Zamioculcas zamiifolia)
Contains calcium oxalate crystals that cause immediate oral burning, drooling, and swelling. Not usually fatal but extremely painful. Dogs are more likely to chew the thick stems; cats may bat at the glossy leaves.
Pothos and Philodendron (Epipremnum and Philodendron spp.)
Contain insoluble calcium oxalates. Cause intense oral irritation, drooling, and difficulty swallowing. Extremely common houseplants that are unsafe for all pets.
Snake Plant (Dracaena trifasciata)
Formerly Sansevieria. Contains saponins that cause nausea, vomiting, and diarrhoea. Mildly toxic but common enough to warrant caution.
Dieffenbachia (Dumb Cane)
Contains calcium oxalate crystals and proteolytic enzymes. Causes severe oral swelling that can obstruct breathing. One of the most dangerous common houseplants.
Aloe Vera
The gel is safe for human skin, but the latex layer beneath the skin contains anthraquinones that cause vomiting and diarrhoea in pets.
Jade Plant (Crassula ovata)
Causes vomiting, depression, and incoordination. Toxic to both cats and dogs.
Tulips and Hyacinths
The bulbs are the most toxic part. Dogs often dig them up in gardens. Cause intense gastrointestinal irritation, drooling, and cardiac abnormalities in large doses.
Azaleas and Rhododendrons
Contain grayanotoxins that affect skeletal and cardiac muscle. Even small amounts cause vomiting, weakness, and potentially fatal heart arrhythmias.
Behaviour Modification Tips
Even with non-toxic plants, you may not want your pets treating your indoor jungle as a salad bar. Here are proven strategies to keep plants and pets coexisting peacefully.
For Cats
Provide alternatives. Cat grass, catnip, and silver vine give cats an acceptable outlet for their chewing instinct. Place these near their favourite plant-targeting spots.
Make plants unappealing. Cats dislike citrus scents. Place lemon or orange peels on the soil surface, or use a diluted citrus spray on the pot (not the plant). Aluminium foil wrapped around pots creates an unpleasant texture.
Physical barriers. Decorative stones on the soil surface prevent digging. Sticky tape (double-sided) on pot rims deters jumping. Motion-activated deterrents that puff air or make noise work for persistent explorers.
Placement strategy. Use ceiling hooks, high shelves, or terrariums for plants you particularly want to protect. Remember that cats are climbers — “out of reach” means genuinely inaccessible, not just high.
For Dogs
Exercise first. A tired dog is less likely to dig or chew. Ensure your dog gets adequate physical and mental stimulation before leaving them alone with plants.
Bitter sprays. Commercial pet deterrent sprays containing bitter apple or grapefruit make plants taste unpleasant. Reapply weekly and after watering.
Secure pots. Use heavy ceramic or concrete planters that can’t be knocked over. Place pots on plant stands with narrow bases that don’t offer a stable platform for jumping.
Supervision and redirection. Catch your dog investigating a plant and redirect to a toy or chew. Consistency is key — dogs learn boundaries faster than cats.
Designated digging zone. If your dog digs in plant pots, provide an approved digging area with sand or loose soil and bury toys or treats there.
If Your Pet Eats a Plant
Despite precautions, accidents happen. Here’s the exact protocol to follow.
Immediate Actions
- Identify the plant. Note the common name, botanical name if possible, and which part was eaten (leaf, stem, flower, bulb).
- Check the ASPCA or RSPCA database on your phone to confirm toxicity status.
- Call your vet or poison helpline immediately if the plant is toxic. Do not wait for symptoms.
UK Emergency Contacts
- RSPCA: 0300 1234 999
- Animal PoisonLine (run by the Veterinary Poisons Information Service): 01202 509000
- Your vet’s out-of-hours service
Information to Provide
- Your pet’s species, breed, age, and weight
- The plant name (common and botanical)
- Which parts were ingested and approximately how much
- Time since ingestion
- Current symptoms, if any
Do NOT
- Induce vomiting unless specifically instructed by a vet. Some toxins cause additional damage on the way back up.
- Wait to see if symptoms develop. Many toxins have delayed onset, and early treatment significantly improves outcomes.
- Attempt home remedies found online. Milk, oil, and other folk treatments can interfere with veterinary treatment.
Red Flag Symptoms (Go to Emergency Vet Immediately)
- Difficulty breathing or swallowing
- Seizures or tremors
- Collapse or extreme lethargy
- Persistent vomiting or diarrhoea (more than 2-3 episodes)
- Blood in vomit or stool
- Swelling around the mouth or face
- Changes in gum colour (pale, yellow, or blue)

FAQ
Are money trees safe for cats? Yes. Pachira aquatica appears on both the ASPCA and RSPCA non-toxic lists. If your cat chews a leaf, expect mild stomach upset at worst.
Are orchids safe for cats? Phalaenopsis orchids are non-toxic to cats and dogs. The flowers may cause mild gastrointestinal upset if eaten in large quantities, but they are not dangerous.
Is a spider plant safe for cats? Yes. Chlorophytum comosum is non-toxic. The dangling babies may attract playful cats, but ingestion is harmless.
Are Calathea plants safe for cats? Yes. All Calathea (now Goeppertia) species are pet-safe. Their moving leaves may fascinate cats, so place them where batting won’t damage the foliage.
Are Boston ferns safe for cats? Yes. Nephrolepis exaltata is non-toxic. The feathery fronds are safe if chewed, though excessive fibre intake may cause mild stomach upset.
What should I do if my cat eats a lily? Go to a vet immediately. Even if you only suspect lily ingestion, treat it as an emergency. Bring a photo or sample of the plant. Every hour counts — kidney damage becomes irreversible after 18-24 hours.
Are succulents safe for pets? Most popular succulents are NOT safe. Aloe, jade, kalanchoe, and euphorbia species are all toxic to pets. Haworthia and echeveria are generally considered safe, but place them out of reach since individual sensitivities vary.
Can I have houseplants if my dog eats everything? Yes, but choose carefully. Stick to the easy-care safe list (spider plant, cast iron plant, parlor palm) and use physical barriers like heavy pots and soil covers. Avoid anything with bulbs or tubers, as dogs often dig these up.
Are herbs safe for pets? Some are; many aren’t. Basil, thyme, and parsley are safe. Mint is safe in small amounts. Rosemary is generally safe but can cause stomach upset in large quantities. Avoid chives, garlic, and onions — these damage red blood cells in cats and dogs.
Do pet insurance policies cover plant poisoning? Most comprehensive pet insurance policies cover accidental poisoning, including plant toxicity. Check your policy details — some exclude “preventable” incidents. Keep receipts for emergency vet visits and plant identification for claims.
The Bottom Line
You don’t need to choose between a beautiful home and pet safety. With 20 verified non-toxic options — from the bulletproof spider plant to the dramatic calathea — you can fill every room with greenery and sleep soundly knowing your pets are safe.
The non-negotiable rule: no lilies if you have cats, no sago palms if you have dogs. Everything else on our safe list gives you flexibility to match your home’s light conditions, your care habits, and your aesthetic preferences.
For plants not on this list, check the ASPCA database before bringing them home. And if you ever face a poisoning emergency, act fast — your vet or the Animal PoisonLine can guide you through the critical first hours.
