5 Common Household Plants That Are Poisonous to Animals

Houseplants brighten the home and create a natural atmosphere that many find both inviting and relaxing, but when you have pets in the home there are more important considerations than the plant's beauty. Although many plants are safe for your pets, some common houseplants pose a threat to your pet's health and may endanger its life, especially if your pet has a tendency to nibble on tender new shoots.
  1. Aloe

    • Aloe poses a risk to cats and dogs.

      Many homeowners grow aloe for its natural healing properties or as first aid for minor scrapes and burns. This plant is both attractive and functional and thrives on sunny windowsills. Unfortunately it poses a risk to cats and dogs. Ingestion may cause vomiting, diarrhea, tremors or a change in urine color. It may also result in depression or anorexia.

    Peace Lily

    • The peace lily causes throat and mouth irritation.

      The peace lily thrives in low light conditions and is often grown atop large decorative vases filled with colored stones and a fish or two. This plant creates a natural environment for the fish and can be used as a focal point in nearly any room. Ingestion of the peace lily causes throat and mouth irritation and burning which may lead to swelling and difficulty swallowing. You pet may show signs of excessive drooling and may vomit.

    Philodendron

    • Prized for its deep green foliage and ability to thrive in low-light conditions, the philodendron creates a tropical feel to the home. This trailing vine can be grown in hanging baskets or trained to climb trellises. Ingesting this plant causes burning of the mouth, tongue and lips. Symptoms include vomiting, excessive drooling and difficulty swallowing.

    Pothos

    • Pothos adds delicate color to the home environment and can be either variegated green and yellow as the golden pothos, or a striking white and green variation called marble queen. Pothos is also known as devil's ivy. Grown in hanging baskets, this plant thrives in low light, making it a favorite for interior design. Ingestion causes burning and irritation to the lips, mouth and tongue. Symptoms include difficulty swallowing, drooling or vomiting.

    Elephant Ear

    • Elephant ear produces large variegated leaves and is often grown as a specimen plant. This plant creates a dramatic show of tropical color ideal for brightening a dark corner or breathing life to a family room. Ingestion causes irritation or burning of the mouth, tongue and lips. Symptoms include vomiting, drooling or difficulty swallowing.

    Holiday Plants

    • Holly berries are toxic to cats and dogs.

      Many use seasonal plants as part of the holiday decor, but this brings with it a host of dangers for pets. Not only are many of these plants poisonous, your pets are likely to explore them because they are new. Beware of mistletoe, holly berries, amaryllis and lilies as they all pose risks to your pets health. According to the ASCPA, poinsettias may cause irritation to the mouth or vomiting, but its toxicity is overrated.

    Considerations

    • Keep questionable plants out of the reach of your pets. This list is not exhaustive and refers to common houseplants only. If you have questions about the safety of a plant, seek the advise of a professional. Several websites, including that of the ASPCA, provide extensive lists of plants harmful to pets (see Resources).
