What Plants Are Toxic To Cats?

Here is a list of the toxic plants that should be avoided if you are a cat owner.

If you own a cat, then you've probably already experienced this. You bring a new plant into the house, and the next time you look at it, there are little teeth marks, and half eaten leaves. For a lot of people this is just a nuisance, but for others who were unfortunate enough to have accidentally purchased a toxic plant, the results can be devastating.

I have had some experience with my cat eating a toxic plant. Fortunately it was just toxic, and not poisonous. My cat only experienced vomiting, and loss of appetite, and the symptoms passed after a day or so. It could have been worse. After that I started keeping a list of toxic plants to avoid in the future. Before I buy a plant for indoors or out, I check the list to make sure I don't bring home anything harmful to my cats, or even the neighborhood cats that go around the community garden I plant in.

Some plants are toxic and can cause illness or even death if consumed in large quantities. Some are poisonous, and will result in death if consumed. It's very important that a cat owner checks the list of poisonous and toxic plants before starting a garden, or buying houseplants.
