Written by Clair Chesterman

Buckeye, often known as Horse Chestnut, is an extremely hazardous tree that can reach 50 feet or more in height. The toxicity of the plant can be linked to glycosides such as aesculin, saponin, fraxin, and perhaps alkaloids, which can be found in the seeds, leaves, and bark. Depression, twitching, mucous membrane inflammation, and vomiting are all common indications of ingestion in cats.
