By the Animal Wellness Desk · Facts last checked October 21, 2026

Each page here reports how the ASPCA Toxic and Non-Toxic Plants database lists a plant for cats, dogs and horses, with the toxic principles and clinical signs it records, then explains what that means for a home with pets. Use the exact plant name where you can: many plants share common names.

Lilies deserve a special mention: several true lilies and daylilies are listed as toxic to cats, with kidney failure among the listed signs. If a cat has touched or chewed a lily, call a vet right away.
