In most cases, people who love their animals also love their houseplants. Houseplants breathe life into a home just like owning a cat does. It seems both pets and houseplants go hand-in-hand, but in reality they can be a deadly combination if the owner is not aware of which plants are toxic to their furry friends.

Any cat owner who also dabbles in gardening or owns houseplants should familiarize themselves with the list below. It’s a surprising list to say the least. Many very common and useful plants are on this list. Even the Aloe Vera plant, known for its medicinal value as a topical treatment for cuts and burns, is poisonous to cats.
