Gerbils are popular pets throughout the UK, and you can find them available for adoption in abundance in our Pets4Homes Gerbil section. Providing your gerbil with a safe, balanced diet is crucial to their health and happiness. As responsible pet owners, understanding what gerbils can safely eat and what to avoid ensures their well-being and longevity. This guide covers the main foods gerbils should have, recommended treats, and important feeding tips.
Most gerbil diets rely on commercially prepared pre-packed food mixes specifically designed for them. These mixes usually contain a variety of seeds, dried fruits, and vegetables aimed at providing balanced nutrition. However, gerbils can be selective and sometimes pick out only their favourite pieces, which might result in an unbalanced diet.
To counter this, supplementing with food pellets is a wise choice. Pellets are formulated by combining all ingredients into a single compact form, ensuring that your gerbil receives complete nutrition with every bite. When feeding, measure the appropriate amount daily to prevent overfeeding and wastage.
Gerbils enjoy certain dried fruits like banana, apple, raisins, sultanas, and apricots because of their natural sweetness. These should be given only as occasional treats due to their high sugar content. Similarly, dried vegetables such as carrot bits, peas, and beetroot are welcomed, but they too must be offered sparingly.
A critical caution: avoid potatoes, and leaves from rhubarb and tomato plants, as these are toxic to gerbils and can cause serious health problems.
Fresh produce can add variety to your gerbil’s diet but must be offered in moderation—about once every week or two in small quantities. Always wash fruits and vegetables thoroughly to remove pesticides and chemicals harmful to gerbils.
Safe vegetables to consider include carrots, broccoli, spinach, and cucumbers. Fruits like small pieces of apple or pear are fine, but remove any uneaten fresh food after a short time to prevent spoilage, which could make your pet ill.
In the wild, gerbils consume insects which provide protein. You can replicate this dietary aspect by feeding live insects, bought from specialised pet stores catering to reptiles. While feeding live insects may seem fiddly or off-putting to some, it is a natural and nutritious treat for your pet.
For ease, freeze-dried insects such as mealworms provide a less messy alternative. Store them in a separate freezer compartment to avoid cross-contamination with human foods and offer these treats occasionally.
Gerbils love seeds like sunflower and pumpkin seeds, but these are high in fat. Therefore, they should be treats rather than staples in the diet to prevent obesity. Avoid salty, roasted, or salted peanuts as these are unhealthy for gerbils.
Raw nuts — such as hazelnuts, cashews, peanuts, and walnuts (unsalted and unroasted) — can be offered occasionally. Remember, moderation is key with all nuts and seeds due to their calorie density.
Use a heavy, sturdy dish for feeding as light plastic containers can be tipped or gnawed through easily. Observe how much your gerbil eats over a 24-hour period to gauge the right daily amount of food, adjusting as necessary to prevent hunger or overeating.
Developing a consistent feeding routine by providing food around the same time each day helps your gerbil anticipate meals and maintain good eating habits. If offering treats, use a separate bowl in a different cage area and remove leftovers after two hours to discourage overindulgence.
Fresh, clean water must always be accessible, ideally through a water bottle attached securely to the cage.
Sudden changes to a gerbil's diet can cause digestive upset. When you bring a new gerbil home, ask the previous owner about its current diet and try to continue with the same food initially. This helps ease stress and transition.
Once your gerbil has settled in, new foods can be introduced gradually and in small quantities over several weeks to allow the digestive system to adjust safely.
Strictly avoid processed human foods like crisps, chocolates, sweets, and cakes as these contain harmful additives, excess sugar, and salt. Toxic foods include potatoes, rhubarb leaves, tomato leaves, grapes, and any mouldy or spoiled produce.
Always ensure any food provided is fresh, organic where possible, and free from chemicals, dyes, or pesticides to protect your pet's health.
Feeding your gerbil a balanced, safe diet involves providing quality commercial pellets, occasional fresh fruits and vegetables, and treats like seeds and insects in moderation. Always prioritise foods formulated for gerbils and introduce new diet items slowly. Avoid toxic and processed foods to keep your small pet healthy and thriving. With thoughtful care, your gerbil will enjoy a happy life full of energy and well-being.
