When it comes to selecting houseplants for your home, it's important to consider the safety of your pets. Some common houseplants can be toxic to dogs, cats, and other pets if ingested. To keep your furry friends safe, here are a few examples of houseplants that should be avoided:

1. Dieffenbachia (Dumb Cane): This popular houseplant is known for its large, attractive leaves. However, it contains calcium oxalate crystals, which can cause oral irritation, intense burning, and swelling of the mouth and throat if ingested.
2. Peace Lily: With its beautiful white flowers, the peace lily is a common choice for indoor gardens. However, it contains calcium oxalate crystals as well, which can cause similar symptoms as the Dieffenbachia if consumed by pets.
3. Pothos (Devil's Ivy): Pothos is a popular trailing plant that is often used in hanging baskets. While it adds a touch of green to any room, it's toxic to pets if ingested. Pothos contains insoluble calcium oxalate crystals, which can cause oral irritation, drooling, and difficulty swallowing.
4. Sago Palm: This decorative palm is a common sight in many households, but all parts of the plant are highly toxic to pets. Ingesting any part of the sago palm can lead to severe symptoms such as vomiting, diarrhea, liver failure, and even death.
5. Lilies: While lilies are undeniably beautiful, they are extremely toxic to cats. Even a small amount of ingestion can cause kidney failure in felines. It's best to avoid having any type of lily in your home if you have cats as pets.

These are just a few examples of common houseplants that can be toxic to pets. It's always a good idea to research any houseplant before bringing it into your home, especially if you have pets. If you suspect that your pet has ingested a toxic plant, contact your veterinarian immediately.
