It is incredibly rare for a snake to be crawling out of a toilet, but it can happen. For example, a neighbor may have a pet snake that happens to get into their owner’s toilet and instead of going to the sewer main it may choose your sewer pipe to slither out of.

To prevent having a snake make its way to your toilet check around and seal up any pipe and drain openings with a metal sieve, mesh or fence, according to http://www.countryliving.com. Make sure the wire spacing is no larger than an inch. Also check for broken sewage pipes that creates an opportunity for snakes to enter. Make sure there is not a rodent infestation that provides snakes their snacks or mealtime.

If the snake got into the sewer main, however, it would probably die of exposure because low temperatures below the ground make it impossible for snakes to survive for long periods of time, unlike alligators, who’ve also been discovered in the sewer. (http://animals.howstuffworks)
