Caladium hortulanum, commonly known as caladium, elephant ears, or taro, is a highly toxic plant to cats. This popular ornamental plant, often found in gardens and as houseplants, poses a severe risk to feline health if ingested.

Caladium contains insoluble calcium oxalate crystals, which can cause intense irritation and swelling in the mouth, throat, and gastrointestinal tract of cats.

Tracing the Roots of the Taro Plant

Caladium is native to the tropical regions of South and Central America, where it grows in the understory of rainforests. The plant has been cultivated for centuries for its striking foliage, which features intricate patterns of green, pink, red, and white. In the 18th century, caladium was introduced to Europe and quickly gained popularity as an ornamental plant in gardens and greenhouses.
