5 Common Houseplants That Are Dangerous for Pets
While houseplants can brighten up your home and purify the air, some can be incredibly dangerous for your pets. Ingesting even small amounts of certain plants can cause symptoms ranging from mild stomach upset to organ failure or death. Here’s a list of five of the most toxic plants for dogs and cats, and what to do if your pet is exposed.
1. Lilies (Lilium and Hemerocallis species)
Lilies are among the most dangerous plants for cats. Even a small amount of pollen or ingestion of any part of the plant can cause severe kidney failure. For dogs, symptoms may include vomiting and gastrointestinal distress, but cats are particularly at risk.
Symptoms of Lily Poisoning:
- Vomitings and diarrhea
- Loss of appetite
- Lethargy
- Increased or decreased urination
2. Sago Palm (Cycas revoluta)
The entire sago palm plant is toxic, but the seeds (nuts) are the most dangerous. Ingestion can lead to liver failure in both dogs and cats, with symptoms appearing within hours of consumption.
Symptoms of Sago Palm Poisoning:
- Vomiting and bloody diarrhea
- Seizures
- Liver damage
- Vomiting
3. Oleander (Nerium oleander)
Oleander is a beautiful but highly toxic plant found in many warm climates. All parts of the plant, including leaves, flowers, and stems, contain toxic glycosides that can disrupt heart function.
Symptoms of Oleander Poisoning:
- Drooling
- Abnormal heart rhythm
- Vomiting and diarrhea

4. Aloe Vera
While aloe vera is often used for skin care, it can be dangerous if ingested by pets. The gel inside the leaves contains compounds that can cause vomiting, diarrhea, and even kidney damage in severe cases.
Symptoms of Aloe Vera Poisoning:

- Diarrhea
- Change in urine color
- Lethargy and tremors
5. Pothos (Epipremnum aureum)
Pothos, also known as Devil’s Ivy, is a common houseplant that is toxic to both dogs and cats. Ingestion can cause oral irritation, drooling, vomiting, and difficulty swallowing.
