5 Common Houseplants That are Toxic to Pets

Houseplants are great! Everyone should have at least one or two live plants in their home! Not only do plants add beauty and colour to your home decor, they can clean the air, and make you feel healthier and happier. And best of all, many of them are easy to grow.

That being said, pet owners need to be aware of the houseplants that are toxic to cats and dogs. Ingesting poisonous plants can make pets very sick! It’s best to keep these plants out of reach. Better yet, avoid bringing any of these plants home, where pets and young children might want to taste them. It is also a good idea to wear gloves when handling toxic plants that could irritate the skin or eyes.
