Instructions
Examine the corn snake's eyes. The eyes should be clear, unless the animal is preparing to shed, in which case an opaque eye cap can appear.
Notice the typical behavior of your corn snake. Although corn snakes aren't always on the move, extended periods of inactivity can point to illness.
Listen to the sound of the corn snake's breathing. If you hear nothing, that's a good sign. Audible breath sounds are abnormal in a corn snake.
Check the nose and mouth for discharge. The nostrils and mouth should be clear; discharge can indicate a respiratory infection.
Run your fingers along the corn snake's body. The skin should be smooth and the snake's body should be free of lumps.
Observe the corn snake's habitat for signs of vomit. You can distinguish vomit from feces in the snake's cage by observing the consistency of the matter. If a snake regurgitates its prey, you can recognize the prey item, whereas fecal matter bears no resemblance to the prey.
Record the corn snake's food intake for several weeks. Although it's normal for corn snakes to refuse food, especially if they're preparing to shed, if the snake shows no interest in food for more than two weeks you should consult a veterinarian.
How to Recognize Illness in Corn Snakes
Corn snakes have relatively few health problems when their owners meet their basic needs for food, water and environment. If your corn snake does develop an illness, the signs are subtle, so you must check the animal frequently and seek treatment before a minor problem escalates into something life threatening.
