Hamsters are adorable little rodents kept as pets by many families across the world. Hamsters are omnivores; in the wild, they live on a diet consisting mainly of plants, seeds, cereals, leaves, plants, and insects. Pet hamsters, therefore, need their diet at home to mimic their original eating habits and requirements as much as possible. However, giving our furry friends a treat is also a pleasure, and part of the fun of owning a small animal!

You may be wondering, then, if you can feed Brussels sprouts to your pet hamster. Is it a safe vegetable to give to them? Brussels sprouts are indeed a great and safe vegetable to feed to your hamster, with many health benefits due to the nutrition these veggies pack. However, there are a few limitations to feeding sprouts to hamsters.

The Benefits of Hamsters Eating Brussels Sprouts

It is advisable to feed a selection of veggies to your hamster every week, and Brussels sprouts are a fabulous vegetable to include. It also appears most hamsters enjoy munching these mini cabbages too.

Many nutrients are contained in sprouts, making them a suitable addition to your hamster’s diet. They are a good source of fiber, antioxidants, and moisture.

100g of raw Brussels sprouts contains:
  • 43 calories
  • 86g water
  • 8 g fiber
  • 38 g protein
  • 2 g sugar
  • 3 g fat

Brussels sprouts also contain Vitamins A, C & K, potassium, phosphorus, calcium and iron.

What Are the Risks of Feeding Brussels Sprouts to My Hamster?

Brussels sprouts are safe to feed to hamsters, but they should be fed raw and fresh, not cooked. Cooking sprouts reduces the nutritional content significantly, plus it seems that hamsters don’t enjoy them as much.

Brussels sprouts belong to a group known as cruciferous vegetables, which include cabbage, broccoli, and cauliflower, to name a few. These are healthy vegetables that are nutrient-rich and high in fiber, which is why they have a reputation for a smelly side effect. While fiber is an important component of a hamster’s diet, too much can cause gas, bloating, or diarrhea – you can have too much of a good thing!

Hamsters are particularly sensitive to gastrointestinal upset, and a simple case of diarrhea can quickly become a serious problem. For this reason, we mustn’t go overboard with the sprouts.

How Many Brussels Sprouts Can a Hamster Eat?

This is always worth checking with your veterinarian for a tailored answer, as it will vary from hamster to hamster, but a general rule of thumb is not to feed Brussels sprouts to baby hamsters and only half a Brussels sprout to adult hamsters twice a week.

Consider cutting the sprout into quarters, and if it is a new veggie for your hamster, try offering one quarter at first to see if it is tolerated and doesn’t cause any upsets.

What Do Hamsters Eat?

The best and most balanced diet for domesticated hamsters includes a daily mixture of roughly:
  • 75% of a pellet compound formulation
  • 20% fresh produce, seeds, animal protein (eg. mealworms, boiled egg)
  • 5% treats, including fruit

Pellets are a commercial diet offering complete nutrition for your hamster. They are readily available from pet stores, supermarkets, or online stores. These complete pellet diets contain all the correct nutrients and amount a hamster needs. Be sure to purchase a complete and balanced diet specifically for hamsters, as diets for other rodents are not the same and cannot be fed instead. Avoid foods that contain a lot of seeds or fruit, as your hamster will likely fill up on these tasty bits, leaving behind the more essential components.

Fresh produce, such as leafy greens, dandelions, and vegetables can be offered daily; they love to eat these types of foods, and they’re good for their health. Remember to provide hay or grass (eg. Timothy hay) that can double as a healthy snack and bedding material – hamsters love to burrow!

  • Apples
  • Raisins
