Cats and houseplants can coexist — but it requires some research upfront. Many popular houseplants are toxic to cats, sometimes seriously so. Lilies in particular can cause acute kidney failure in cats with even minimal exposure. The good news is that there are dozens of beautiful, easy-to-grow plants that are completely safe for cats, and many of them are widely available and easy to care for.

This guide covers the best cat safe plants for your home — organized by type, with care notes for each.

Important Note on Plant Toxicity

The ASPCA maintains the most comprehensive database of plant toxicity for pets. When in doubt, always cross-reference a plant at aspca.org before bringing it home. “Non-toxic” means a plant won’t cause serious harm, but some non-toxic plants can still cause mild stomach upset if eaten in quantity — which is common with cats who chew on leaves.

Best Cat Safe Houseplants

1. Spider Plant (Chlorophytum comosum)

Spider plants are one of the most cat-friendly houseplants available. They’re non-toxic, nearly indestructible, and one of the best air-purifying plants you can own. They produce arching green-and-white leaves and long runners with small “spiderettes” at the tips that can be propagated easily. They tolerate low light, irregular watering, and thrive in hanging baskets — which also keeps them somewhat out of reach of determined cats.

Note: spider plants have a mild hallucinogenic effect on cats similar to catnip, which is why some cats find them irresistible. If your cat is obsessed with chewing the leaves, hang the plant higher.

2. Boston Fern (Nephrolepis exaltata)

Boston ferns are lush, feathery, and completely safe for cats. They’re one of the most effective air-purifying plants available and love humidity — making them excellent for bathrooms. They do need consistent moisture and bright indirect light to thrive, which makes them slightly more demanding than other options on this list. Let the soil dry slightly between waterings, but don’t let it dry completely.

3. Areca Palm (Dypsis lutescens)

If you want a dramatic, floor-standing plant that’s safe for cats, the areca palm is one of the best choices available. It produces elegant, feathery fronds and can grow several feet tall indoors. It prefers bright indirect light and slightly moist soil. It’s also an excellent air humidifier — the fronds release moisture and improve indoor air quality.

4. Calathea / Maranta (Prayer Plants)

Prayer plants are named for their habit of folding their leaves upward at night. They come in stunning varieties — Calathea orbifolia, Calathea zebrina, Maranta leuconeura — with bold patterns of green, white, pink, and purple. All are non-toxic to cats. They prefer indirect light and consistent moisture, and will tell you they need humidity by getting crispy leaf edges.

5. Haworthia

Haworthias are small, architectural succulents that look similar to aloe but are completely non-toxic to cats (unlike aloe, which is toxic). They’re slow-growing, need minimal water, and tolerate lower light than most succulents. Perfect for windowsills and shelves where curious cats might explore. See our low light houseplants guide for other shelf-friendly options.

6. Orchids (Phalaenopsis)

Phalaenopsis orchids — the most common orchid sold in grocery stores and garden centers — are non-toxic to cats. They’re elegant, long-blooming (often months per bloom cycle), and more resilient than their reputation suggests. They need bright indirect light, weekly watering (soak and drain — never let them sit in water), and a potting mix of bark chips rather than soil. When the blooms drop, cut the spike and wait — a new one often emerges.

7. Air Plants (Tillandsia)

All Tillandsia species are non-toxic to cats, making them ideal for cat households. Since they need no soil, they can be mounted on walls, placed on shelves, or displayed in open terrariums — well away from curious paws. See our full air plant care guide for everything you need to know.

8. Money Tree (Pachira aquatica)

The money tree is a popular, braided-trunk houseplant that’s completely safe for cats. It tolerates low light (though it prefers bright indirect light), infrequent watering, and average humidity. The distinctive braided trunk is created by weaving multiple young stems together while they’re pliable — giving it a sculptural quality unlike most houseplants.

Plants to Avoid in Cat Households

For reference, here are some of the most commonly kept houseplants that are toxic to cats:

  • All true lilies (Lilium and Hemerocallis species) — extremely toxic, can cause kidney failure. Keep these out of any home with cats entirely.
  • Pothos — causes oral irritation and vomiting. Very common and very toxic to cats despite being practically indestructible.
  • Philodendron — similar toxicity to pothos.
  • ZZ plant — toxic if ingested.
  • Peace lily — causes oral irritation, excessive drooling, and vomiting.
  • Snake plant — mildly toxic, causes nausea and vomiting.
  • Aloe vera — toxic to cats despite being useful for humans.

Many of the most popular and easy-to-grow houseplants appear on this toxic list. The safe alternatives in the first section of this guide are chosen specifically to fill the same decorative roles without the risk.

Practical Tips for Plant-Owning Cat Households

  • Elevation helps — cats are curious but often don’t bother with plants they can’t reach. Wall-mounted planters, high shelves, and hanging baskets put toxic plants out of reach while keeping your décor intact.
  • Give cats their own plants — a pot of cat grass or catnip redirects chewing behavior away from your houseplants.
  • Lemon or orange peels — citrus scents deter most cats naturally. Place peel in the soil around plants you want to protect.
  • Know the ASPCA number — if your cat does eat something concerning, the ASPCA Animal Poison Control Center is available 24/7 at (888) 426-4435 (a consultation fee applies).
