Basic Information about Corn Snakes

Corn Snakes

Corn snakes are non-venomous constrictor snakes that originate from North America. They are commonly found in the southeastern United States, where they inhabit a variety of habitats, including forests, grasslands, and farmlands. These snakes are renowned for their patterned scales, which resemble the colors and patterns found on maize, hence the name “corn snake.”

In captivity, corn snakes thrive when provided with suitable enclosures that mimic their natural environment. This includes maintaining appropriate temperatures, providing hiding spots, and ensuring a clean and secure habitat. Proper nutrition is also crucial for their overall well-being.

How long can corn snakes go without eating?

All snake species are different when it comes to food. Some snakes can go up to two or three months without eating, and some ball pythons they have been known to go without food for up to two years! Like most snakes, corn snakes can happily survive without eating every day.

Small snakes have to feed more often than large snakes. Their increased appetite is due to the fact that snakes can only eat as much food as their bodies can hold. Because a large snake can eat more food at once, it can go longer between meals as its body takes longer to digest and use a large amount of food.

Baby snakes need to feed more often than adult snakes. A baby snake needs to eat at least once a week or else it will starve. Upon reaching adulthood, an average snake can go without food for two to three weeks.

Natural Fasting Periods

Corn snakes, particularly adult individuals, may undergo voluntary fasting periods even when provided with suitable food. This behavior is normal and should not cause concern. Some corn snakes may voluntarily refuse food for two to three weeks or even longer. It’s essential to monitor their weight and overall condition during these fasting periods.

Environmental Factors

Changes in the environment can affect the feeding behavior of corn snakes. For example, a sudden change in temperature, inadequate hiding spots, or excessive noise and disturbances in their surroundings may cause temporary loss of appetite. Ensuring a stable and stress-free environment is crucial for maintaining a healthy feeding schedule.

Health and Stress Levels

Corn snakes can also go off feed due to health issues or stress. Infections, parasites, or underlying medical conditions can lead to a loss of appetite. Additionally, factors such as recent relocations, improper handling, or excessive disturbances can cause stress and result in a decreased desire to eat. If your snake consistently refuses food for an extended period or shows other signs of illness, it’s important to consult a veterinarian.

What Happens When a Corn Snake Doesn’t Eat?

How long can corn snakes go without eating

A pet corn snake can go a few weeks or even months without eating. However, it is not good to let your snake go hungry for so long. Your snake will likely get sick if it eats just one meal every few months.

Without food, a snake’s body will begin to feed on its own tissue for calories and survival. In the beginning, the body will use the fat for energy. Once the available fat is used up, it will turn into muscle.

When the body has used up its available stores of fat and muscle, it will begin to break down internal organs such as the liver, kidneys, heart and brain. Eventually, the damage will lead to organ failure, cardiac arrest, and death.

Healthy snakes don’t have much body fat. Since a snake has no fat reserves to draw on, it won’t be long before the body begins to break down its muscles and internal organs for energy.

Signs of Hunger in Corn Snakes

As a corn snake owner, it’s essential to be familiar with the signs that indicate hunger or potential health issues. Some common signs of hunger in corn snakes include increased activity, tongue flicking, exploring the enclosure in search of food, and displaying a keen interest in prey items. On the other hand, a snake that is sick or stressed may exhibit signs like lethargy, weight loss, regurgitation, or abnormal behavior. Regularly monitoring your snake’s behavior and body condition can help you detect any changes and take appropriate action.

How often should corn snakes be fed?

How often should corn snakes be fed?

Unlike other pets, you don’t need to feed a snake every day. The chicks need to be fed about once every five to seven days. You should feed a young snake once every seven to ten days. Once a corn snake reaches adulthood, you can feed it once every ten to fourteen days.

Factors Affecting Feeding Frequency

Several factors influence the feeding frequency of corn snakes, and understanding these factors is essential for providing optimal care.

Age and Size

As mentioned earlier, younger corn snakes require more frequent feedings due to their rapid growth. As they mature, their feeding frequency can be reduced. Additionally, the size of the snake also plays a role in determining the appropriate meal size and frequency.


Each corn snake has a unique metabolic rate, which influences how quickly they digest and process food. Some snakes may have a faster metabolism and require more frequent feedings, while others may have a slower metabolism and need less food. Monitoring the body condition of your snake can help determine if adjustments to the feeding schedule are necessary.

Seasonal Changes

Corn snakes, like many reptiles, experience seasonal changes in their behavior. During the winter months, they enter a period of reduced activity known as brumation. During this time, their metabolism slows down, and they may not eat for several weeks or even months. It is crucial to replicate these natural cycles in captivity to ensure the overall well-being of the snake.

When to Seek Veterinary Assistance?

If your corn snake consistently refuses food for an extended period or shows signs of illness, it’s essential to seek veterinary assistance. A reptile veterinarian experienced in treating snakes can conduct a thorough examination, perform diagnostic tests if necessary, and provide appropriate treatment. Timely veterinary intervention can help identify and address any underlying health issues.

Feeding Tips for Corn Snakes

Feeding Tips for Corn Snakes

To ensure your corn snake remains healthy and well-nourished, consider the following feeding tips:

  1. Use pre-killed or frozen-thawed rodents to eliminate the risk of injury to your snake during feeding.
  2. Offer appropriately sized prey items that match the girth of your snake. A general rule of thumb is to offer prey that is no larger than the thickest part of the snake’s body.
  3. Provide a separate feeding enclosure to prevent the ingestion of substrate during feeding.
  4. Feed in the evening or early morning when corn snakes are naturally more active.
  5. Observe your snake during feeding to ensure it consumes the prey item correctly and doesn’t regurgitate.
  6. Maintain a clean and hygienic enclosure to minimize the risk of bacterial or parasitic infections.

How long can a corn snake go without water?

A corn snake can go up to a week without water, but it’s not healthy for them to do so. Your snake needs to drink clean water just like any other living thing. Make sure your snake has a constant supply of fresh, clean water in a snake-sized plate.

Can a corn snake survive if it refuses to eat?

Yes, corn snakes can survive for extended periods without eating. However, consistent refusal to eat or signs of illness should be addressed promptly to ensure the snake’s health.

How do I know if my corn snake is fasting or sick?

Signs of fasting in corn snakes include voluntary refusal of food, maintaining body weight, and overall good health. Signs of illness may include weight loss, regurgitation, abnormal behavior, or other symptoms of illness. Consult a veterinarian if you suspect your snake is sick.

Can I offer live prey to my corn snake?

It is generally recommended to feed pre-killed or frozen-thawed prey to corn snakes to eliminate the risk of injury to the snake and to ensure the safety of the prey item.

Is it normal for a corn snake to go off feed during shedding?

Yes, it is common for corn snakes to reduce or stop feeding during the shedding process. It is essential to provide a stress-free environment and offer food after the snake has completed shedding.

Final Word

In conclusion, corn snakes possess an incredible ability to survive for extended periods without eating. Their unique metabolic adaptations and efficient energy utilization allow them to go without food for several weeks or even months.

However, it’s important to note that while corn snakes can withstand periods of fasting, regular feeding is essential for their overall health and well-being. As responsible snake owners, it’s our duty to provide them with a proper diet and monitor their feeding habits closely.
