What Do Gerbils Eat?

Small pets like the hamster and gerbil are often described as great options for children, but that isn’t always the case.

A gerbil is an energetic and entertaining pet, but it works best for older children who can handle the gerbil with care and manage the responsibility.

Gerbils are burrowing rodents native to Africa and Asia, where there are several wild breeds. Most of the gerbils you find in pet stores, however, are descendants from Mongolian gerbils.

These little rodents grow up to 4 inches long and get another 4 inches from their long, furry tails.

They are social animals, best kept in same-sex pairs, and they can become very tame with frequent handling. They typically don’t bite unless they feel threatened.

With proper care, a pet gerbil can live up to 8 years. In most cases, however, pet gerbils live 2 to 3 years.

The key to maintaining pet gerbil health and happiness is to provide your pet with a nutritious diet.

Read on to learn more about your gerbil’s nutritional needs and how to meet them in the best way possible.

Read on to learn the essential components of your gerbil’s diet and to see our recommendations for feeding.

Types of Gerbil Diets

Many pet owners compare the gerbil to the hamster, but it’s important to realize that these are two different animals.

Though hamsters and gerbils are both technically omnivores, the gerbil prefers a vegetarian diet.

Your gerbil might do fine on a commercial hamster food, but his specific nutritional needs will be better met by a properly formulated gerbil mix.

Here is a quick breakdown of the different components of a pet gerbil’s diet:

  • Seed Mixes – One of the most common gerbil foods, seed mixes contain a variety of seeds and grains, along with other ingredients like dried fruit and nuts. However, gerbils tend to pick out their favorite foods and leave the rest, leading to a possible nutrient deficiency.
  • Balanced Pellets – A commercially balanced pellet is the best way to meet your gerbil’s minimum requirements for key nutrients, but some gerbils simply don’t like them – you may need to offer them along with a seed mix.
  • Nuts & Seeds – If you’re feeding a commercially balanced pellet, nuts and seeds can be added as treats. Control your gerbil’s intake of high-fat options like cashews and sunflower seeds. The nuts and seeds should be uncooked and free of salt, seasonings, or other flavorings.
  • Fruits & Vegetables – Fresh fruits and vegetables can make up a small part of your gerbil’s diet. Seed mixes and balanced pellets provide the majority of his nutrition. If you do feed your gerbil fruits and vegetables, wash them thoroughly and scrub them to remove dirt.

A balanced diet for gerbils is essential for optimal health and wellness. Keep reading to learn the basics about your gerbil’s nutritional requirements and how they can be met with a commercial gerbil mix.

Meeting Your Gerbil’s Nutritional Needs

When shopping for gerbil food, remember to keep your pet’s nutritional needs in mind. These are omnivorous animals, so they require a variety of foods in their diet.

The nutritional content of your gerbil’s food should come primarily from carbohydrates, with moderate protein content (about 15% to 16%) and low-to-moderate fat content (2% to 20%).

Younger and more active gerbils may need higher fat percentages to account for increased calorie burn.

Regarding specific nutrients, gerbils need high levels of fat-soluble vitamins like vitamins A, D, E, and K. These can be found in natural seeds and grains, so that’s why seed mixes are such a good diet for gerbils.

Choose a well-balanced seed mix, though, to avoid giving your gerbil too much fat. For example, pumpkin seeds and sesame seeds are recommended over sunflower seeds, because sunflower seeds have too much fat. Make sure that your gerbil’s food has a good blend of ingredients.

Gerbils don’t have significantly different nutritional needs based on age because they tend to live for only a few years. Baby gerbils, however, must be fed their mother’s milk or formula for the first three weeks of life.

After that, you can introduce small pieces of solid food, including commercial pellets and peeled sunflower seeds.

After a few months, your gerbil should be ready to eat a 50/50 mix of commercially balanced pellets and seed mix, with small amounts of fresh vegetables and fruits.

Occasional treats include boiled eggs, unsweetened yogurt, or dried mealworms or crickets.

To give you an idea of what gerbils eat and how much you should feed your pet gerbil during different life stages, refer to this chart:

Daily Guinea Pig Feeding Chart

Age Size Pellets or Seed Mix Veggies and Fruits Treats
Up to 3 weeks Baby Mother’s milk or formula only
3 weeks to 3 months Juvenile Small amounts of gerbil pellets, peeled sunflower seeds, raw oats Very small amounts of fresh veggies and non-citrus fruit 1-2 times a week
3 months and up Adult Half commercially balanced pellets, half seed mix Very small amounts of fresh veggies and non-citrus fruit 1-2 times a week Boiled egg, unsweetened yogurt, dried mealworms
Pregnant and nursing mothers Adult Half commercially balanced pellets, half seed mix Very small amounts of fresh veggies and non-citrus fruit 1-2 times a week Boiled egg, unsweetened yogurt, dried mealworms

Most gerbil owners offer their gerbil its food in a small, heavy bowl that can’t be knocked over. Some gerbils prefer to forage, so you might try sprinkling some food around the cage as well.

In addition to providing your gerbil with the right food, you also need to make sure that he has access to fresh water.

Gerbils don’t tend to drink a lot of water, but you should still provide it in a small water bottle hung where your gerbil can easily access it.

These formulas are designed to provide for the nutritional needs of gerbils and are formulated for their digestive systems. Plus, they are convenient for you as a pet owner.
