Pet-Safe Houseplants — The Complete Guide
Last Updated: February 2026
TL;DR
Many popular houseplants are toxic to cats and dogs, including pothos, monstera, philodendron, and lilies. Safe alternatives that are genuinely non-toxic include spider plants, Boston ferns, calatheas, peperomias, and most palms (areca, parlor, ponytail).

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.
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.
