how long can a squirrel live without food

by food

The average lifespan of a squirrel is between 5-10 years, however, how long a squirrel can survive without food is strongly dependent on various factors such as the species, age, health and the environment. Generally, an adult squirrel can live for several days without food but it is not recommended that it goes longer than that.A squirrel can typically survive for up to two weeks without food. However, if the squirrel is unable to find food in that time, it will eventually die from starvation.

Environmental Conditions

The ability of a squirrel to survive without food depends largely on the environmental conditions in which it lives. Squirrels need access to water, shelter, and a safe environment in order to survive without food. If the environment is too cold, too hot, or too dangerous, then a squirrel will not be able to survive for long periods of time without food.

Access To Shelter

In order for a squirrel to survive without food, it must have access to some sort of shelter. This could be a tree cavity or some other type of den that provides protection from weather and predators. Without adequate shelter, the squirrel will not have the necessary protection to survive for long periods without food.


A squirrel’s ability to adapt is also important in its ability to survive without food. If a squirrel can easily adjust its behavior and diet in response to changes in its environment or availability of resources, then it will have an easier time surviving even during times of food scarcity.

Food Availability

In addition to environmental conditions and adaptability, the availability of food also plays an important role in a squirrel’s ability to survive without food. If there are no sources of food available within reach for the squirrel then it may not be possible for it to find enough sustenance in order to stay alive.

Nutritional Needs of a Squirrel

Squirrels are omnivorous mammals, meaning they eat both plants and animals for sustenance. They have specific nutritional needs that should be met in order to stay healthy and thrive in their environment. The primary components of a squirrel’s diet include proteins, carbohydrates, vitamins, minerals, and water.

Protein is essential for providing energy and helping to build and maintain the body’s tissues and organs. Squirrels eat nuts, seeds, fruits, insects, eggs, small birds, small mammals such as mice or voles, and occasionally carrion (dead animals).

Carbohydrates provide energy for the body’s cells to function properly. Squirrels mainly get their carbohydrates from fruits and nuts. They also eat fungi such as mushrooms or lichens.

Vitamins are needed for proper growth and development as well as helping the body to fight off disease. Squirrels consume a wide variety of plant foods that provide them with vitamins A, B complex (thiamine, riboflavin), C, D & E vitamins.

Minerals are important for maintaining the balance of fluids in the body as well as helping to form bones and teeth. Squirrels obtain minerals from nuts (including calcium), grains (including iron), mushrooms (including potassium) and insects (including sodium).

Water is also important in a squirrel’s diet; it helps keep their body temperature regulated while also aiding digestion. They usually obtain water from food sources such as fruits or dew on foliage or ground coverings like mosses or lichens.

What Happens if a Squirrel Doesn’t Receive Enough Nutrition?

A squirrel that does not get enough nutrition can become malnourished, which can lead to serious health problems. A malnourished squirrel may experience weight loss, lethargy, and an overall decrease in vitality. They may also suffer from a weakened immune system, making them more susceptible to diseases and infections. In some cases, malnutrition can be fatal.

In order to ensure that squirrels receive the proper nutrition they need, it is important to provide them with a balanced diet. Proper nutrition for squirrels includes a variety of foods such as nuts, seeds, fruits, vegetables, insects, and fungi. Additionally, allowing squirrels access to natural sources of food such as tree bark and leaves is also beneficial for their nutritional needs.

It is also important to ensure that squirrels have access to clean water at all times. This helps keep the squirrels hydrated and ensures proper digestion of food. Additionally, providing supplemental vitamins and minerals can help provide additional nutrients for the squirrels when natural sources are unavailable or inadequate.

If you suspect that a squirrel is not receiving enough nutrition or is malnourished in any way, it is important to seek veterinary care immediately. Professional advice should always be sought before attempting any nutritional interventions on your own.

How Much Food Does an Adult Squirrel Need Per Day?

Adult squirrels typically need about one to two ounces of food per day. This amount can vary depending on the size and activity level of the squirrel. A larger squirrel may need more food, while a smaller one may not need as much. In general, a healthy adult squirrel should be fed a diet that includes fresh fruits and vegetables, nuts and seeds, grains, and occasional snacks such as nuts or raisins.

Fruits and vegetables should make up the bulk of an adult squirrel’s diet. Apples, pears, bananas, carrots, celery, and broccoli are all excellent sources of vitamins and minerals that help keep the animal healthy. Fruits and vegetables should be given in small pieces or diced for easy consumption. Nuts like peanuts and almonds are also important sources of protein for squirrels; they should be given in small amounts daily or every other day.

Grains such as oats, wheat germ, barley, millet, cornmeal, buckwheat groats or hulled oats can also be provided to the adult squirrel to supplement their diet. These grains should be given in moderation as they are high in carbohydrates which can lead to obesity in some animals. Occasional treats such as nuts or raisins can also be offered but should never exceed 10% of the total daily calorie intake for an adult squirrel.

It is important to provide your adult squirrel with a balanced diet that meets all their nutritional needs on a daily basis. If you are unsure about what type of food your particular animal needs it is best to consult with your veterinarian or a qualified wildlife rehabilitator who can help you determine the appropriate diet for your furry friend.

What Types of Foods Do Squirrels Eat?

Squirrels are omnivores, which means they eat both plants and animals. In the wild, squirrels eat a variety of nuts and seeds, as well as fungi, eggs, insects, and even small vertebrates. They also eat fruits such as apples, cherries, and plums.

Nuts and seeds are the mainstay of a squirrel’s diet. Acorns, walnuts, hazelnuts, almonds and pine nuts are all favorites. Squirrels also enjoy sunflower seeds, peanuts and other nuts found in birdseed mixes. Fungi provide an important source of nutrition for many species of squirrels in the wild; they often feed on mushrooms or truffles. Insects such as caterpillars are also part of their diet.

In addition to these natural foods, some species of squirrels have adapted to eating human food sources such as birdseed mixes that contain grains or dried fruits. They may also forage in garbage cans for scraps or leftovers from meals. In urban settings where there is a plentiful food source available year-round from humans, some populations of squirrels have become completely reliant on human-provided foods.

It is important for squirrel owners to understand that although many human foods can be fed to squirrels safely in moderation (e.g., fruits and vegetables), they should not be fed too much processed or sugary foods due to health concerns. Additionally, it is strongly recommended that owners provide their pet squirrel with a variety of different natural foods to ensure a balanced diet.

Can a Squirrel Survive on Fruits and Vegetables Alone?

Squirrels are known to be omnivores, meaning they eat both meat and plant-based foods. While they typically consume a variety of items including nuts, seeds, insects, and even bird eggs, it is possible for them to survive on a strictly plant-based diet.

Fruits and vegetables can provide squirrels with the necessary vitamins and minerals that they need for survival. Fruits like apples, oranges, cherries, melons, bananas and grapes can provide them with energy and fiber. Vegetables like carrots, celery stalks, green beans, spinach leaves and kale can provide them with essential vitamins such as vitamin A, C and K.

In addition to these food items, squirrels also need access to fresh water. This can be provided by bird baths or shallow dishes of water placed in the yard or garden. It is also beneficial to supplement their diet with nuts or seeds every few days in order to provide them with additional nutrients.

Overall, while it is possible for a squirrel to survive on a strictly plant-based diet of fruits and vegetables alone, it is important to supplement their diet occasionally with nuts or seeds in order to ensure they are receiving all the necessary vitamins and minerals they need for optimal health.

How Long Can a Baby Squirrel Go Without Food?

Baby squirrels are very dependent on their mothers for food and warmth. In the wild, they typically feed on their mother’s milk until they are around 8-10 weeks old. After that, they start to explore outside of the nest and look for other sources of food, such as nuts, seeds, fruits, and insects.

However, baby squirrels can go without food for a short period of time if their mothers leave them alone or become separated from them. In these cases, it is important to remember that baby squirrels have very small stomachs and will need to be fed small amounts of formula or puppy milk replacer every two hours or so in order to stay healthy.

It is also important to note that baby squirrels can quickly become dehydrated if they do not have access to adequate amounts of water. If a baby squirrel has been separated from its mother for more than 24 hours, it is important to seek help from a wildlife rehabilitator or veterinarian in order to ensure that the animal is properly cared for.


A squirrel can survive without food for up to 3 days, depending on the availability of water and shelter. During this time, they will conserve energy by entering a state of torpor. After the three-day period, the animal’s body will begin to break down its fat reserves in order to sustain itself. This can be dangerous as it puts the squirrel at risk of dehydration, hypothermia, and starvation if food is not found.

It is important to remember that squirrels are very adaptable animals and can survive in many different environments. When providing food for squirrels in your yard or garden, it is important to remember that they should only be fed a balanced diet and not overfed. Providing food that is rich in protein and carbohydrates will ensure that they remain healthy and live longer lives.

In conclusion, a squirrel can live without food for up to 3 days if it has access to water and shelter. It is important for humans living around wild squirrels to provide them with a balanced diet and not overfeed them in order to ensure their health and longevity.
