Snakes just love cool, wet, and dark places and that’s why your toilet pipes can be very intriguing to them. But, what drives them there in the first place is the sewer that has food remnants that they can feed on. When they are finished with their food in the sewer, they will look for a way out and the pipes are the easiest and quickest route. However, you shouldn’t be afraid if you live in a cold environment, since snakes will only sneak up in toilets in warm countries.
