Plants That Are Poisonous to Pets

Pets are incredibly curious creatures who are not above snacking on anything that interests them. When that snack is a plant, problems can occur. Many plants are poisonous if eaten and can cause symptoms ranging from mild discomfort to death. Below is a list of some of the most common plants that sicken pets.

Aloe Vera

The leaves of the aloe vera plant offer quick relief for burns, but eating these plants can cause vomiting, diarrhea, decreased appetite, changes in urine color and tremors in both dogs and cats.

Amaryllis

These flowering plants provide a splash of color during the holiday season, but they can be poisonous to pets. Keep bulbs out of the reach of your cats and dogs, as these are the most toxic part of the plant. Sampling an amaryllis plant can cause drooling, loss of appetite, vomiting, diarrhea, abdominal pain, tremors and depression.

Azalea and Rhododendron

Eating azalea or rhododendron plants can cause symptoms that range from mild to life threatening. The severity of the symptoms vary depending on how much of the plant your cat or dog eats, but it only takes a small amount to make an animal sick. Symptoms include vomiting, diarrhea, drooling, loss of appetite, abnormal heart rate, weakness, abdominal pain, tremors, blindness, seizures and comas.

Baby's Breath

Found often in floral arrangements, these white flowers can cause vomiting, diarrhea, loss of appetite, lethargy and depression if they are ingested.

Buttercups

Cheerful yellow buttercups certainly do not look very threatening, but they can cause drooling, vomiting, diarrhea, weakness, tremors or seizures if eaten. Buttercup flowers are very bitter and cause mouth ulcers. In most cases, pets decide that buttercups are not so tasty after all, after a few bites.

Daffodils

The bulbs are also the most toxic part of daffodils. If your pet eats a daffodil, it may experience drooling, vomiting and diarrhea. Eating several daffodils can cause low blood pressure, heart arrhythmias, tremors and convulsions.

Holly, Mistletoe and Poinsettias

Eating one of these classic holiday plants can cause a range of symptoms. Although poinsettias have a bad reputation, eating them really only causes mild irritation to the mouth or stomach. Mistletoe is more dangerous. Eating it can result in gastrointestinal disorders, heart problems, hallucinations, vomiting and diarrhea. Consuming holly can also cause vomiting and diarrhea, but your pet may be most annoyed by the tiny cuts caused by the spiny leaves.

Morning Glories

You may notice some very unusual behavior if your pet eats morning glories. Symptoms include hallucinations, stomach upset, tremors, loss of appetite and difficulty controlling movements or balance.

Mountain Laurel

Mountain laurel plants produce attractive flowers in the spring, but eating these plants can be deadly. If your pet consumes mountain laurel, it may begin to drool and experience vomiting, diarrhea, heart rhythm abnormalities, tremors, coma and even death.

Tomato Plant

If your pet cannot resist eating the leaves and stems of a tomato plant, you may notice drooling, loss of appetite, diarrhea, drowsiness, confusion, weakness, slow heart rate, dilated pupils or changes in behavior.

Tulips

Munching on a tulip bulb can cause stomach problems, loss of appetite, drooling, convulsions and cardiac problems.

  • "I began working for Dr. Kaiser at the Animal Clinic of Mandarin over 3 years ago. I decided
    to get a new Lab mix puppy and made the decision to enroll Zuri in Trupanion. I made this
    decision after hearing other employees and Dr. Kaiser talking about how great it has been for
    their own pets and our clients.
    Within the first 6 months my puppy Zuri’s knee kept coming out of place and she would stiffen
    up and could only walk on 3 legs. She had to have surgery and between working with Dr. Kaiser
    and the specialist I couldn’t have been happier that I was able to take care of Zuri and give her
    the treatment that was needed at such a young age. I now have no worries as she grows older
    that I won’t be able to take care of her financially. I recently added a new 1 year old rescue Great
    Dane, Zane to our family. He also has Trupanion because I can’t imagine the cost if something
    happens to him being such a large dog."

  • "Dr. Kaiser and staff are awesome. Great customer service. They deal with the pet insurance company directly for you so you don't have to pay what is covered directly out of pocket. They have gone above and beyond to help our fur baby. Super clean! We love to see Harry (the beautiful St. Bernard) growing up as well!"

  • "I called and was able to get an appt the same day. The office was very clean and customer service was very exceptional. Dr. Kaiser took her time to go explain everything and get a thorough history. Sick call exam and consultation came up to $51.75. She also offered a deal on pet insurance. Overall we had a very good experience."
