As the holidays draw near and homes across Utah begin filling with festive décor, it’s important for pet owners to remember that some seasonal plants can pose risks to dogs and cats. While these plants add beauty and tradition to your home, they can also cause stomach upset or more serious health concerns if pets chew on them. Taking a few precautions—such as keeping plants elevated or choosing pet-safe alternatives—can help you enjoy the season without an unexpected trip to the veterinarian.
Below is a closer look at common holiday plants, how they can affect pets, and what to do if exposure occurs.
Poinsettias
Poinsettias are one of the most recognizable holiday plants and are commonly found in homes throughout Utah during December. While they have a reputation for being extremely dangerous, their toxicity is often overstated.
The poinsettia plant contains a milky white sap made up of compounds known as diterpenoid euphorbol esters and saponin-like detergents. If a dog or cat chews on the leaves or stems, these substances can irritate the mouth and digestive system. Typical symptoms include mild vomiting, drooling, or diarrhea.
If the sap comes into contact with your pet’s skin, you may notice temporary itching or mild irritation. In most cases, symptoms are short-lived and resolve on their own without medical treatment. However, if your dog or cat continues to feel unwell, seems lethargic, or symptoms worsen, it’s always wise to consult your veterinarian for peace of mind.
Christmas Trees
Whether you choose a freshly cut pine from a local Utah tree lot or an artificial option, Christmas trees are generally safe for pets with a few precautions.
Natural trees themselves are not toxic, but problems can arise if pets chew on pine needles or branches. Sharp needles can irritate the mouth, throat, or stomach, and in rare cases may become lodged in a pet’s eye or paw. Tree sap can also cause mild stomach upset if ingested.
Another concern is tree water. If preservatives or fertilizers are added to the stand, drinking from it can upset your pet’s stomach. Covering the base of the tree and keeping ornaments, tinsel, and lights secured will reduce the risk of accidents.
Mistletoe
Mistletoe is one holiday decoration that should always be kept completely out of reach of pets. Unlike poinsettias, mistletoe is highly toxic to dogs and cats.
Ingesting mistletoe can lead to serious symptoms such as vomiting, diarrhea, slowed heart rate, difficulty breathing, low blood pressure, and changes in behavior or coordination. Because of the severity of potential reactions, immediate veterinary care is essential if you believe your pet has eaten any part of the plant.
Holly
Holly is another festive plant commonly used in wreaths, garlands, and table displays, but it can be dangerous for pets. The leaves and berries contain substances that irritate the gastrointestinal tract.
Pets that ingest holly may experience vomiting, diarrhea, drooling, lethargy, and stomach discomfort. While symptoms can vary depending on how much was consumed, it’s best to contact your veterinarian if holly ingestion is suspected, especially if your pet shows signs of distress.
Other Holiday Plants to Avoid
In addition to poinsettias, mistletoe, and holly, there are several other seasonal plants that should be considered off-limits for pets:
-
Amaryllis – Can cause vomiting, diarrhea, abdominal pain, and drooling.
-
Daffodils – Toxic bulbs can lead to gastrointestinal upset and, in severe cases, heart rhythm abnormalities.
-
Lilies – Extremely dangerous for cats.
A Special Warning About Lilies
Lilies deserve special attention, particularly in homes with cats. Even small amounts—such as pollen brushed onto fur and then licked—can cause acute kidney failure in cats. Symptoms may include vomiting, loss of appetite, lethargy, and dehydration. Immediate veterinary treatment is critical, as early intervention can be lifesaving.
Dogs are less sensitive to lilies than cats, but ingestion can still result in stomach upset.
Keeping Pets Safe During the Holidays
While holiday plants add warmth and charm to your home, pet safety should always come first. Here are a few simple tips to reduce risks:
-
Place plants on high shelves or in rooms your pets cannot access.
-
Avoid decorating with highly toxic plants if you have curious pets.
-
Clean up fallen leaves, needles, or berries promptly.
-
Monitor your dog or cat for signs of plant exposure, including vomiting, drooling, lethargy, or changes in behavior.
-
Contact your veterinarian right away if you suspect poisoning.
With a little planning and awareness, you can enjoy a festive Utah holiday season while keeping your furry family members safe, healthy, and happy.
