poisonous plants for petsHome owners are often surprised to learn that many of the plants that decorate their homes are toxic for their cats and dogs.  Indeed, when ingested by dogs and cats some of the most poisonous plants can even cause death.  This article will introduce some of the most poisonous plants to dogs and cats as well as the symptoms of accidental ingestion.  If you notice any of these symptoms you need to visit your veterinarian right away.  It is also recommended that you keep a list of the plants you have in your home so that you can easily identify substances that your dog or cat may have eaten.

With their large green leaves and tropical beauty, cycad palm plants are a favorite among homeowners in warmer climates but Cycad palms like the sago palm, false sago palm, and the queen sago palm are toxic to cats and dogs.  Cycad palms contain cycasin and while the entire plant is poisonous the seeds are even more dangerous.  Some of the symptoms associated with cycasin poisoning are:

  • Vomiting
  • Excessive thirst and water consumption
  • Increased salivation
  • Reduced appetite
  • Diarrhea
  • Constipation
  • Yellow coloration of the skin and gums
  • Seizures and other neurological problems

Despite their beauty, lilies are poisonous for cats. Easter lilies, tiger lilies, stargazer lilies, and some species of day lilies are toxic to cats as they cause kidney damage. Some of the symptoms of lily toxicity may appear within a few hours of ingestion and include:
