Pet-Safe Houseplants — The Complete Guide
Last Updated: September 2026
TL;DR
Many popular houseplants are toxic to cats and dogs, including pothos, monstera, philodendron, dieffenbachia, and lilies. Safer alternatives that are commonly listed as non-toxic include spider plants, Boston ferns, calatheas, peperomias, cast iron plants, and parlor palms. Non-toxic does not mean edible, though: any plant material can still cause vomiting or stomach upset if a pet eats enough of it.

Check Your Plant by Name
Use the botanical name on the nursery label. These guides explain the safety listing, common mix-ups, and what to do if leaves have been chewed.
Are spider plants safe for dogs?
Chlorophytum comosum
Non-toxic to cats and dogs; chewing can still upset a stomach.
Are Boston ferns safe for pets?
Nephrolepis exaltata
Check that the plant is a Boston fern, not an asparagus fern.
Are bromeliads pet safe?
Check the exact species
A broad label like “bromeliad mix” is not a species identification.
Are cast iron plants safe for pets?
Aspidistra elatior
Check the safety listing and learn how to limit chewing.

What to Do If Your Pet Eats a Toxic Plant
- 1.Stay calm and remove any plant material from your pet's mouth
- 2.Identify the plant — take a photo for the vet and confirm the plant name with a reliable source
- 3.Contact your vet or the ASPCA Animal Poison Control Center (888-426-4435)
- 4.Do not induce vomiting unless specifically instructed by a veterinarian
- 5.Monitor for symptoms: drooling, vomiting, lethargy, difficulty breathing
How to Verify a Plant Before Buying
Use the scientific name when checking toxicity. Common names are messy: "fern" can mean Boston fern, asparagus fern, or foxtail fern, and those are not the same plant. Search the exact botanical name on a trusted toxicity database, then keep a photo of the nursery tag in case your vet needs it later.
If a plant is only labeled with a broad trade name like "tropical foliage" or "bromeliad mix," treat it as unknown until you identify it. You can use our Plant Identifier Quiz for common houseplants, then confirm the safety listing before placing it within reach of pets.

Frequently Asked Questions
Most succulents are non-toxic to cats, including echeveria, haworthia, and hens-and-chicks. However, some popular "succulents" like aloe vera and jade plant (Crassula ovata) are toxic to cats. Always verify the specific species before assuming safety.
Pothos contains calcium oxalate crystals that cause immediate oral pain, drooling, and swelling if chewed. While rarely fatal, it causes significant discomfort. Seek veterinary advice if your cat ingests pothos, especially if symptoms include difficulty swallowing or excessive vomiting.
Spider plants (Chlorophytum comosum) are non-toxic to both cats and dogs. However, cats are often attracted to the dangling leaves and may eat them, which can cause mild digestive upset (vomiting) due to the fiber content, not toxicity.
Boston ferns are listed by the ASPCA as non-toxic to both cats and dogs. The main practical issue is access: fronds can still be chewed, pulled down, or cause mild stomach upset if a pet eats a lot of plant material.
Many common bromeliads are generally treated as pet-safer houseplants, but plant labels can be vague and bromeliad is a broad group. Verify the exact species or cultivar before buying, and keep sharp-edged leaves out of reach of playful pets.
No. Philodendrons, including popular types such as Philodendron Birkin, are not pet-safe choices for cats or dogs. They contain insoluble calcium oxalates that can irritate the mouth and throat if chewed.
The most dangerous common houseplants include lilies (can cause kidney failure in cats), sago palm (highly toxic to dogs), dieffenbachia, oleander, and philodendron. Lilies are particularly dangerous — even pollen contact can be life-threatening to cats.
Place toxic plants on high shelves, in hanging baskets, or in rooms pets cannot access. Use bitter apple spray as a deterrent. Provide pet grass or catnip as safe alternatives. However, the safest approach is to only keep non-toxic plants if you have curious pets.
