Plants and Flowers Poisonous to Pets

If you plan to spruce up your yard this spring, and you have a pet that likes to spend time outdoors, you should take care to avoid certain plants which can be toxic when ingested. The ASPCA estimates that there are over 700 species of plants which are toxic to pets. According to the UC Davis School of Veterinary Medicine, the reaction to toxicity ranges from mild discomfort to life-threatening, depending on factors such as the species of plant, the amount ingested, and type of animal which was exposed. Here is a list of the most common plants that are toxic to cats and dogs. For a more exhaustive list, or to search for a particular plant, please visit the ASPCA Toxic Plant Gallery List.

Yard Maintenance Products

Most common yard maintenance products such as fertilizer, mulch, insecticides, and herbicides are highly toxic to our pets and children. Luckily, there are many nontoxic organic alternatives on the market. For example, EcoSmart, Espoma, and Safer are brands which specialize in organic gardening supplies.  These brands and many others can be found in stores such as Lowes, Home Depot, Target, and Walmart.  If your pet spends a significant amount of time outdoors, it is recommended you use an organic option when possible. Eco-friendly products are just as effective and your furry friend will be safe.
