Indoor Plants Safe for Cats: The Complete Guide
Cat owners who love houseplants face a real challenge: many popular indoor plants are toxic to cats. Cats are curious creatures who love to nibble on leaves, bat at hanging fronds, and dig in soil. The good news? There are dozens of gorgeous houseplants that are completely safe for your feline friends.
The Best Cat-Safe Houseplants
🌿 Spider Plant (Chlorophytum comosum)
The spider plant is a cat owner's dream. It's completely non-toxic, incredibly easy to grow, produces charming baby plants on cascading stems, and is excellent at purifying indoor air. Cats love to play with the dangling plantlets, and while they might nibble the leaves (which can act as a mild hallucinogen for cats — similar to catnip), it won't harm them. Grows well in bright indirect light and tolerates neglect.
🌿 Boston Fern (Nephrolepis exaltata)
Lush, cascading, and completely safe for cats. Boston ferns are a classic houseplant that adds a tropical feel to any room. They prefer humid conditions and indirect light, making them perfect for bathrooms. The frilly fronds are irresistible to playful cats but totally harmless.
🌿 Calathea (Various species)
Calatheas are famous for their stunningly patterned leaves — stripes, spots, and deep purples. The entire Calathea genus (also sold as Goeppertia) is non-toxic to cats. Popular varieties include Calathea ornata (Pinstripe), Calathea medallion, and Calathea lancifolia (Rattlesnake Plant). They like humidity and indirect light.
🌿 African Violet (Saintpaulia)
Want flowers? African violets are one of the easiest flowering houseplants and completely cat-safe. They bloom in purple, pink, white, and bi-color varieties. Keep them in bright indirect light and water from the bottom to avoid leaf spots.
🌿 Peperomia (Various species)
The entire Peperomia genus is non-toxic to cats. With hundreds of species ranging from trailing varieties to compact rosette forms, there's a peperomia for every spot in your home. Watermelon Peperomia and Peperomia obtusifolia are particularly popular.
🌿 Parlor Palm (Chamaedorea elegans)
A true palm that stays compact enough for indoor growing and is safe for cats and dogs. Parlor palms tolerate low light and add an elegant tropical touch to any room. They're slow-growing and low-maintenance.

Plants to AVOID If You Have Cats
These common houseplants are toxic to cats and should be kept out of your home or placed completely out of reach:
- Lilies (Lilium and Hemerocallis): The #1 most dangerous plant for cats. Even small amounts of pollen, leaves, or flower water can cause fatal kidney failure. Easter Lilies, Asiatic Lilies, and Daylilies are all extremely dangerous.
- Pothos (Epipremnum aureum): Very popular trailing plant but causes oral irritation and vomiting in cats.
- Monstera (Swiss Cheese Plant): Contains calcium oxalate crystals causing mouth pain and swelling.
- Snake Plant (Sansevieria): Causes nausea, vomiting, and diarrhea in cats.
- Dieffenbachia: Intense oral burning and swelling that can obstruct airways.
- Philodendron: Similar oxalate crystal toxicity to Monstera and Dieffenbachia.
- Aloe Vera: Causes vomiting, diarrhea, and lethargy.
- Sago Palm: Extremely toxic — can cause liver failure and death.
Tips for Cat-Proofing Your Plants
Even with cat-safe plants, some cats are determined plant destroyers. Here's how to protect your plants (and your cat):
- Use hanging planters — some cats can't reach them (though many will try).
- Create a cat garden — grow cat grass, catnip, or catmint to give your cat their own plants to munch on.
- Cover soil with stones — prevents digging and makes the pot less appealing as a litter box.
- Use citrus deterrents — most cats dislike citrus scents. Place orange peels around plants or use a citrus spray.
- Provide alternatives — cats often chew plants out of boredom. More playtime and enrichment can reduce plant nibbling.
