Personally, I do not name my snakes. However, I feel that people name their snakes because they consider them "pets" or part of their family. In a way it's almost anthropomorphizing the animals. I do not see my snakes as pets therefore I do not name them. I do not name my fish either for the same reason. I do consider my cats pets though and they have names. At some point in the process of keeping snakes, or anything, the number of individuals gets too high and the whole scheme of things turn from pets to projects. That being said, show me a rancher that has names for everyone of his cattle.
