Toxic Plant List: Lilies Kill, and Common Houseplants Must Go

The top danger is true lilies and daylilies: petals, leaves, pollen, even vase water can cause acute kidney injury, and pollen licked off fur counts as exposure. Suspected contact means an immediate vet visit before symptoms appear; the safest rule is no lily bouquets in a cat home.

Other common hazards include pothos, monstera, dieffenbachia (oral irritation), ivy, sago palm (severe liver toxicity), azalea, and tulip bulbs. Chewing plants is feline nature, so high shelves are not protection; remove toxic plants and substitute cat grass, spider plants, or Boston ferns.

Before buying plants, verify Latin names against databases like the ASPCA list since common names mislead. If the cat chews something suspect, photograph and save a sample, clear the mouth, and call a vet; the sample speeds identification dramatically.
