How do we take care of a corn snake? Now to start off with, this little fellow that I have in my hand is actually a king snake, but they are very similar. They are of the same class. They’re constrictors. Corn snakes and rat snakes are almost one and the same, and as you can see from the pictures, they have more of a marbled appearance, instead of the colors as the king snake, the California king snake. They come in quite a few different morphs nowadays and you’ll get very, very interesting patterns and colors with your corn snakes.
