A friend sent me this link and thought it might be of interest to anyone with house plants or even plants growing in their yard (or in the case of horses, in the pasture). The ASPCA site provides information on plants that are toxic and non-toxic to dogs, cats, and horses. You can look the plants up by their scientific or common name and you can also view which plants are dangerous for the specific type of animal you are concerned about (so you can click and pull up all the plants that are toxic only to cats). The site also shows photos of the plants so you can compare what your pet ate to the picture and make sure it is the same plant.
In addition, the site provides a 24-hour emergency poison hotline that you can reach in case you cannot contact your own vet and are concerned about the plant your pet ate. That number is 1-888-426-4435.
