Is Wisteria Toxic to Cats

Wisteria is toxic to both cats and dogs. Wisteria is a lovely but extremely invasive vine that will take center stage and envelop the other plants and herbs in the yard, eventually taking over the entire garden. Wisteria seeds and pods contain toxic lectins that are particularly hazardous to cats. The lectins enter the circulation and cause red blood cells to coagulate. Wisteria vine also includes the poisonous glycoside wisterin, which is harmful to cats. 

Even wilted wisteria leaves are deadly to dogs and cats. The poisonous glycoside wisterin found in the leaves produces gastrointestinal issues such as stomach pains, nausea, vomiting (oftentimes with blood), diarrhea, and even depression.
