Can Hamsters Eat Wheatgrass?

In this article we will wind out if wheatgrass is safe to eat for hamsters. TLDR wheatgrass is OK to feed hamsters in small amounts, read on to find out more about the benefits of wheatgrass for hamsters.

What Is Wheatgrass?

Wheatgrass is the young grass of wheat plants, usually harvested before it reaches 6 to 14 inches tall. Wheatgrass is also known as cereal grass and winter grass, and it is a type of annual grass.

Wheatgrass has a mild, sweet taste. Many claim that wheatgrass juice can be used as a treatment for several different ailments or conditions.

Wheatgrass contains high levels of vitamin A and C as well as essential minerals like magnesium, potassium, calcium, and iron. Because it’s rich in nutrients (especially vitamins), wheatgrass has been praised for its anti-aging properties.

Can Hamsters Eat Wheatgrass?

Let’s answer the question, can hamsters eat wheatgrass? Yes, they can, just make sure it is clean before feeding it to your hamster.

Wheatgrass is healthy and nutritious for hamsters, but it can be dangerous if your pet consumes too much of it. According to the Rodale Institute (a non-profit agricultural institute), wheatgrass should not be given to young hamsters in large quantities because they will consume too much of it. Their small stomachs cannot accommodate such rich food, and their digestive systems might get upset from the high fiber content in wheatgrass.

Benefits Of Wheatgrass For Hamsters

There are many healthy and nutritious benefits that you can get from giving your pet wheatgrass. For instance, here’s a list of benefits:

  • Wheatgrass is high in vitamin A and C, calcium, iron, and magnesium (which is why it has been regarded as anti-aging)
  • Can boost energy levels
  • Can improve skin conditions
  • Can reduce inflammation
  • Can help wounds heal faster due to the high content of chlorophyll in wheatgrass.

The downside to wheatgrass for hamsters is that because there are very few studies conducted on its effect on the digestive system and other aspects of hamster health, we cannot say exactly how much they can consume safely or what harmful effects arise from excess intake. That being said, since it is safe for humans and other animals to eat wheatgrass, we can assume that hamster-friendly quantities of wheatgrass will not harm your pet and might even provide health benefits.

Risks Of Wheatgrass For Hamsters

As with any food, there are always risks in feeding your pet too much of it. In the case of wheatgrass for hamsters, too much can cause digestive issues such as gas and bloating. These might not kill your pet but they can make them feel uncomfortable or depressed when accompanied by weight loss or lack of appetite.

Don’t Feed Too Much Wheatgrass To Your Hamster

Since we do not have enough information about how much wheatgrass a hamster can safely consume in a day, we cannot say that it’s safe to feed them large quantities of it regularly. However, if you wish to give your beloved pet some wheatgrass from time to time, don’t give more than 4-5 blades at one go.

Hamsters are known for storing their food, and this can cause problems for a couple of reasons.

If any wheatgrass are left uneaten in your hamsters cage, they could rot, start to smell and attract insects.

Your hamster may also store uneaten wheatgrass in their cheek pouches, and it’s not uncommon for hamsters to develop abscesses, which can be sore for your pet.

That’s why it’s advisable to monitor your hamster when giving them wheatgrass and immediately remove and discard any uneaten wheatgrass from their cage.

How To Feed Wheatgrass To Your Hamster

Since wheatgrass is packed with vitamin C, your hammy will benefit greatly from having some of it in its diet. You can consider using wheatgrass as a treat for your pet once or twice a week, making sure you never exceed the suggested amount per serving (4-5 blades). Try to find fresh wheatgrass instead of buying ready-to-use wheatgrass products because the latter might contain preservatives that are not good for your pet’s health.

Here’s a quick and simple way to feed your pet:

  • Find some fresh wheatgrass and rinse it under running water. Make sure there are no insects, soil or other debris on the blades before feeding them to your hamster.
  • Grasp four to five blades of grass with your fingers, then place them in your hamster’s cage.
  • Watch as they eat up all the wheatgrass you gave them! Remember not to give more than 4-5 blades at one go.

As with the introduction of any new food to your hamsters diet, if you are going to try feeding your hamster wheatgrass, you need to monitor your hamster closely whilst eating them.

How Much Wheatgrass Can A Hamster Eat?

To sum it up, wheatgrass for hamsters is safe in moderation and might even provide health benefits. So if you want to give your pet something nutritious with a nice flavor, consider wheatgrass as an option. Again, never feed more than 4-5 blades at one serving and monitor them when eating the grass so they do not get harmed.

When feeding your hamster new foods, you should always start with a tiny amount to ensure that they like it, and that they don’t encounter an allergic reaction. So if you want to try feeding your hamster wheatgrass then we would recommend giving a very small portion size, about the size of a teaspoon.

Another good way to work out what is the right amount of wheatgrass to feed your hamster is to give them a portion they can comfortably hold within their hands.
