Pet-Safe Houseplants: A Guide for Cat and Dog Owners
If you share your home with a cat or dog, plant choice matters. Several of the most popular houseplants are toxic to pets, and a curious animal that chews a leaf can end up seriously unwell. The good news is that there are plenty of attractive, genuinely pet-safe plants.
Popular plants that are toxic to pets
Avoid these, or keep them strictly out of reach, if you have animals that chew:
- Pothos and philodendron, contain insoluble calcium oxalates that irritate the mouth and digestive tract
- Snake plant, mildly toxic, causes nausea and vomiting
- ZZ plant, irritating if chewed
- Peace lily, irritates the mouth and throat
- Dieffenbachia (dumb cane), notably irritating
- Aloe vera, toxic to cats and dogs despite being useful for humans
- Lilies, true lilies are extremely dangerous to cats in particular
This is not a complete list. When in doubt, check the plant against the ASPCA’s toxic and non-toxic plant database before buying.
Genuinely pet-safe houseplants
These are non-toxic to cats and dogs and still easy to care for:
Spider plant (Chlorophytum comosum). A tough, forgiving plant, and completely pet-safe. Cats are often drawn to its dangling leaves, which is harmless.
Calathea and Maranta (prayer plants). Strikingly patterned foliage, non-toxic. They want higher humidity and indirect light, so they are a little more demanding.
Parlour palm (Chamaedorea elegans). A classic, elegant, pet-safe palm that tolerates lower light well.
Boston fern (Nephrolepis exaltata). Lush and pet-safe. It wants steady moisture and humidity.
Peperomia. A large, varied group of compact, non-toxic plants. Many are easy and drought-tolerant.
Areca palm (Dypsis lutescens). A larger pet-safe choice for filling a corner with bright indirect light.
African violet (Saintpaulia). Compact, non-toxic, and flowers indoors.
Practical advice beyond plant choice
Even with non-toxic plants, it is worth discouraging chewing. Soil can upset a pet’s stomach, and a destroyed plant is no fun either.
- Place tempting plants on shelves or in hanging pots.
- Give cats their own cat grass to chew, which redirects the urge.
- A non-toxic plant is safer, not a licence to ignore a pet that eats everything.
If you suspect your pet has eaten a toxic plant, contact your vet promptly rather than waiting for symptoms.
