My whole life as a country gal I never knew snakes could shoot a foul smelling substance from their rear! Until yesterday when I attempted to remove a large bull snake from my feed shed. As I tried to scoop it up with a hoe it squirted skunky white stuff out. Looked it up in a snake book and on the internet and this is not uncommon. It is uric acid produced during digestion that they can store as a defense! I live in snake country and never encountered this!
