Which Plants Are Pet-Safe?

If you're sharing your home with a curious cat or a dog who treats every low-hanging leaf like a snack, plant shopping comes with an extra question: will this hurt them? The good news is that there are plenty of beautiful, completely pet-safe options — but there are also some common houseplants that range from “might cause an upset stomach” to “call the vet right now.” Here's how it breaks down.

Completely Pet-Safe

These plants are non-toxic to both cats and dogs, meaning even a curious nibble shouldn't cause any poisoning. (Note: “non-toxic” isn't the same as “designed to be eaten” — a pet that eats a large amount of any plant, safe or not, can still get a mild stomach ache from the fiber alone.)

• Spider plant — a classic pet-safe pick, even though cats are often oddly drawn to chewing on it.

• Boston fern — lush and completely non-toxic, great for a hanging basket out of reach anyway.

• Calathea and prayer plants — safe for cats and dogs, with the bonus of dramatic leaf patterns.

• Peperomia — compact, low-maintenance, and non-toxic — a good choice for shelves pets can reach.

• Parlor palm and areca palm — safe palm options if you want height without the risk (skip the sago palm — more on that below).

• Haworthia and echeveria — pet-safe succulents, though not all succulents are (see the gray area below).

• African violet — a flowering option that's fully non-toxic to cats and dogs.

Not Safe At All

These are the ones to keep out of the house entirely if you have pets, or at minimum keep somewhere they can truly never access. Some can cause serious or even life-threatening reactions.

• True lilies — extremely dangerous for cats; even small amounts of pollen or leaf can cause fatal kidney failure. This is the single biggest one to know.

• Sago palm — every part of the plant is toxic, and it's one of the most dangerous common houseplants for dogs.

• Dieffenbachia (dumb cane) — causes intense oral irritation, drooling, and swelling if chewed.

• Oleander — affects the heart and is toxic to both pets and people — not a plant to bring indoors.

• Autumn crocus — can cause severe vomiting and organ damage; distinct from the pet-safe spring crocus.

The Gray Area: Mildly Toxic

This group won't usually cause a life-threatening emergency, but it can still mean a rough day (or a vet visit) if your pet takes a real bite. Worth knowing about even if you decide to keep them, out of reach.

• Pothos and philodendron — contain calcium oxalate crystals that irritate the mouth and stomach; rarely dangerous but very unpleasant.

• Peace lily — despite the name it's not a true lily, but it's still mildly toxic and can cause mouth irritation and vomiting.

• Snake plant and ZZ plant — mild toxicity, typically leading to drooling or an upset stomach rather than anything severe.

• Aloe vera and jade plant — popular succulents that are mildly toxic — fine on a high shelf, best avoided at nose height.

The Takeaway

The safest approach is to check any specific plant before you bring it home, since “pet-safe” can vary even within a single plant family. When in doubt, keep new plants somewhere your pet can't reach until you've confirmed it's a safe one.
