Non-toxic plants for cats: the verified list and the pitfalls

The easiest cat-safe houseplants to live with indoors are Chamaedorea, Areca and Kentia palms, Beaucarnea, Calatheas, spider plants, Boston ferns, Peperomias, Hoyas, Rhipsalis and Phalaenopsis orchids: all are listed as non-toxic to cats in the ASPCA database (American Society for the Prevention of Cruelty to Animals), which we checked species by species.

By contrast, there is one group that should be absolutely banned from homes with cats: true lilies (Lilium) and daylilies (Hemerocallis), which can cause fatal kidney failure, according to the FDA (Food and Drug Administration, the US health agency).

This guide sorts it all out: a large comparison table to help you choose based on your light, a list of toxic plants commonly found in garden centers, cat grass, what to do if your cat ingests a plant, and a link to each plant's care guide.

Do you also have a dog? our guide to non-toxic plants for dogs covers their specific needs, our article on Calathea and pets explains the specifics of Calathea, and our guide to indoor palms compares true and false palms.

🌟 Why cats require stricter plant selection than dogs

Cats require stricter plant selection because they climb, chew leaves out of curiosity and groom themselves: they can ingest a toxin without even biting the plant, simply by licking pollen that has fallen on their paws or coat, as the University of California, Davis School of Veterinary Medicine (UC Davis) points out.

Dogs, on the other hand, stay on the ground and tend to chew whatever is at nose height. According to the behavior guide from Cornell, cats chew plants for play, exploration or because they crave greenery: nibbling is therefore normal behavior, which should be redirected rather than forbidden.

Finally, the Cornell Feline Health Center (Cornell University) notes that lilies, tulips, foxglove and philodendron are among the hundreds of plants known to be toxic to cats.

📊 Cat-safe indoor plants compared

Here are 13 indoor plants verified one by one, across 12 rows: 11 listed as “Non-Toxic to Cats” on the ASPCA page for the species or genus, Maranta, whose ASPCA pages “Maranta” and “Prayer Plant” actually give the scientific name Calathea insignis, and Pilea peperomioides, which the ASPCA does not list but NC State considers safe for pets.

Choose first according to your light, then according to the space available: large palms add structure to a living room, while smaller species fit on a shelf. Each row links to the full care guide and the source page consulted.

🪏 How to make your home safe for your cat

To make your home safe, start by identifying every plant by its Latin name, remove those that are toxic, then bring back only verified species. The order matters: an inventory without Latin names can miss mix-ups, because the same common name sometimes refers to several species.

Our pet-friendly plant collection brings together the plants we have checked, while all our indoor plants lets you find more options to suit your light.

🧭 Plants toxic to cats: keep these out of reach

The plants toxic to cats most commonly found in garden centers are lilies, aroids (Monstera, Pothos, Spathiphyllum), and plants rich in saponins (Dracaena, Sansevieria, Aloe). Aroids contain insoluble calcium oxalate crystals that burn the mouth; saponins mainly cause digestive problems.

We sell some of these plants: they are still perfect for homes without pets, and each product page clearly indicates their toxicity.

The ASPCA also lists Crassula (jade plant) (Crassula care guide), Syngonium (Syngonium care guide), and Kalanchoe as toxic; its bufadienolides cause vomiting, diarrhea, and, rarely, irregular heart rhythms, according to the ASPCA; Cornell also lists Philodendron.

Croton is considered mildly toxic by NC State Extension, which reports nausea, vomiting, and diarrhea following significant ingestion. For the coffee plant, the ASPCA classifies coffee and caffeine as dangerous to animals: keep its berries out of reach.

📐 Lilies: the number one danger for cats

Lilies are the most dangerous plants for cats: according to the FDA (Food and Drug Administration, the US public health agency), eating a small piece of leaf or petal, licking a few grains of pollen from their coat, or drinking vase water can be enough to trigger kidney failure, which develops within 24 to 72 hours and is fatal without treatment.

This applies to all Lilium (Asiatic, Easter, Oriental, Stargazer, and tiger lilies) and daylilies (Hemerocallis).

Early signs (lethargy, drooling, vomiting, loss of appetite) appear within 0 to 12 hours, followed by kidney symptoms between 12 and 24 hours. The University of California, Davis School of Veterinary Medicine (UC Davis) states that treatment delayed by more than 18 hours generally leads to irreversible kidney failure, and recommends not bringing lilies into the home or planting them in the garden if you have a cat.

Beware of false lilies: Spathiphyllum and calla lilies irritate the mouth without affecting the kidneys, while lily of the valley (Convallaria majalis) can cause heart problems, according to UC Davis and the FDA.

📐 Cat grass: catnip or grasses?

The term cat grass refers to two different things, and the distinction matters. Catnip (Nepeta cataria) is the plant that excites or calms cats: the ASPCA lists catnip (Nepeta cataria) as toxic, as it can cause vomiting and diarrhea; it should therefore be given in moderation.

Grasses sold in pots for nibbling (oat, wheat, barley), on the other hand, meet the need to chew: the Cornell Feline Health Center behavior guide recommends offering cats oat grass, catnip, and catmint to distract them from houseplants.

For the garden, our catmint guide explains how to grow these perennials that cats love. The same Cornell guide reminds us that the only sure way to protect both cats and plants is to block access to the pots.

📐 My cat ate a plant: what to do

If your cat has eaten a plant and you are unsure whether it is toxic, call your veterinarian or a veterinary poison control center immediately and provide the plant’s exact name.

According to the French National Veterinary Council, the CNITV in Lyon (+33 4 78 87 10 40) and CAPAE-Ouest in Nantes (+33 2 40 68 77 40) answer calls from 8:30 a.m. to midnight, seven days a week; CAPAE-Ouest states that its service is free.

The CNITV (VetAgro Sup, Lyon) says it receives calls from both veterinarians and the public. Cornell emphasizes one point: do not induce vomiting unless specifically instructed by a professional. If your cat has eaten a lily, do not wait for symptoms: the 18-hour window mentioned above can affect the prognosis.

🗓️ Cats and plants through the seasons

Risks to cats change with the seasons because bouquets, holiday plants, and trips between the balcony and living room vary throughout the year.

Spring is the season for Easter lilies, summer for garden daylilies, and winter for bouquets and holiday plants. The Cornell Feline Health Center (Cornell University) reminds us that chewing a small poinsettia leaf can be enough to make a cat ill.

🐛 Common mistakes with cats and plants

The most common mistake is assuming a non-toxic plant can be eaten without limit: the ASPCA itself points out that eating any plant material can cause vomiting and digestive upset in dogs and cats. Other mistakes mainly stem from misleading common names and the false sense of security that comes from putting plants up high.

🌿 Our selection of cat-safe plants

Here are care guides for verified plants, to help you grow them successfully once you have made the right choice. Available plants are grouped in our pet-friendly plant collection, and trailing species in our hanging plants collection.

🔑 Rhipsalis, Phalaenopsis and bromeliads: safe choices often overlooked

Rhipsalis and the Phalaenopsis orchid are useful additions to the list: the ASPCA lists Rhipsalis (ASPCA: Rhipsalis cassutha) and the Phalaenopsis genus (ASPCA: Phalaenopsis) as non-toxic to cats.

Rhipsalis trails in long, slender stems, making it perfect for a hanging planter; the orchid looks lovely on a table or bright windowsill.

For Pilea, the ASPCA only lists Pilea cadierei (non-toxic), which is why we rely on NC State Extension (North Carolina State University), which describes it as safe for pets and children.

With bromeliads, it depends on the genus: NC State Extension lists Guzmania lingulata as non-toxic to cats, dogs and horses, and the ASPCA says the same of Neoregelia; the pineapple plant, with its spiky leaves, is a different matter, as our bromeliad guide explains.

✅ Our tips for a cat-safe indoor jungle

A cat-safe indoor jungle comes down to three rules: no lilies or daylilies, choose only species verified by their Latin names, and provide cat grass to redirect chewing. Palms, ponytail palms, Calatheas, Chlorophytum, ferns, Peperomia, Hoyas, Rhipsalis and Phalaenopsis orchids cover every light level.

Finally, keep the CNITV and CAPAE-Ouest phone numbers handy: if in doubt, a quick call is better than waiting.
