Is Calathea Toxic to Dogs and Cats? (2026)

No treatment is needed. It prefers higher humidity and can get crispy leaf edges in dry air — that's a care issue, not a sign of pet-related harm.

Calathea is not known to contain toxic compounds harmful to dogs, cats, or horses.

Calathea is confirmed non-toxic to dogs and cats by the ASPCA. It's grown almost entirely for its strikingly patterned leaves rather than for flowers, and like its close relative the Prayer Plant, its foliage visibly folds upward at night and unfolds again during the day — a movement called nyctinasty that's easy to notice if you check on it morning and evening.
