What else to know
Peace lily is not a true lily. It belongs to the arum family (Araceae), with pothos and monstera. True lilies (Lilium) are a different matter for cats: ASPCA lists kidney failure as the sign, while for dogs it lists them as non-toxic.
The name alone tells you little: if a cat chewed a “lily”, what ASPCA lists depends on which lily it was.
Look-alikes
- True lily (Lilium): toxic to cats, non-toxic to dogs (ASPCA). ASPCA lists kidney failure in cats; dogs are on the non-toxic list. A different risk from peace lily.
- Calla lily: toxic to cats, toxic to dogs (ASPCA). Same family, same verdict and same oxalate signs as peace lily. Also not a true lily.
Care basics
Light: Part to deep shade. Keep it out of direct sun.
Soil and water: Keep the soil moist but not soggy, and let it dry a little between waterings. Watering from below works well. It likes 68 to 85°F by day.
