Also, like all oats that are raw remember to soak them in water before feeding your pet so that it can wash away any dirt picked up during harvesting.

Oats provide a good source of fiber for your hamster and can promote healthy digestion. The fiber in oats also helps to maintain a pet’s digestive system by feeding the good bacteria that live inside of them.


Since oats are high in protein, it can help maintain your hamsters muscle growth. Protein is one of the most important nutrients for a hamster.

Baby hamsters need at least 20% protein in their diet while an adult requires only 18%. If you were to feed your hamster a 100 grams of oats this would be around 16 grams of protein.

Teeth And Gums:

The oats will also aid in keeping your pet’s teeth and gums strong to avoid any dental problems later on down the road.

Another benefit is that they won’t develop tooth cavities like their rodent counterparts who eat mostly sugar or sweet food items instead. This applies to other small pets too like mice, guinea pigs.

What Are The Disadvantages?

The most common diet for a hamster is exclusively made of oats and water. Unfortunately, this can lead to many health problems if they are not fed other foods in small amounts. 

For example, they may develop other issues related to weight gain. Therefore, if you plan on feeding your hamster oats it is recommended that you also feed them a variety of other healthy foods like vegetables and fruits for optimal health.

Phosphorous & Sodium:

While oats are good for your hamster, they also contain a lot of phosphorus and sodium. If you notice your pet gaining weight or having trouble breathing, then it could be because of these two elements.

They’re especially known for causing health issues when given to young hamsters (under one year). For example, excess phosphorous can lead to stunted growth and ill health while too much sodium may cause fluid retention in the abdomen.

Allergic Reactions:

Oats are related to wheat which can also be a problem if your hamster has an allergy to any of these grains. If that is the case then please avoid giving them oats because they will only make their allergies worse and could lead to medical problems such as stunted growth due to malnutrition.

And lastly, while oats are available at almost all pet stores, it may not always be in stock and you may have trouble finding it in bulk packages.

So depending on where you live you may need to purchase multiple bags from different stores just so you have enough for your hamster(s) consumption per day.

Weight Gain:

If you overfeed your hamster, then that can lead to significant weight gain and over a longer period of time, it could cause health problems such as heart disease and joint pain.
