Cats are curious by nature. They sniff, nibble, and sometimes chew on plants around the home—often without us noticing. While many houseplants are harmless, some popular decorative plants can be dangerous or even life-threatening to cats. Knowing which plants to avoid (or keep well out of reach) is an essential part of creating a cat-safe home.
