Do Hamsters Like Blueberries?

How Much Blueberry Can A Hamster Eat?

Most of us can eat blueberries by the bowlful – but given a hamster’s tiny size, it makes sense that their serving is a whole lot smaller. Good news though – that means more for you!

Here’s how much blueberry to feed your hamster:

Age Amount
Baby hamster None
Adult hamster 1 large blueberry or 2 small blueberries

Hamsters are very easy pets to care for, but you do need to take time to introduce new foods properly, including blueberries. The reason for this is that any sudden dietary change can lead to problems like indigestion and diarrhea.

If your hamster already eats fruit, go ahead and offer a large blueberry. If this is their first time having anything sweet, give them the smallest blueberry you can, or split a larger berry in half to make sure that they don’t have to much sugar at once.

After your hamster tastes their blueberry, they’re likely to beg for more – but don’t give in just yet. Spend the next 12 hours or so watching for signs of diarrhea or digestive distress. If your hamster is fine, then you can give them another bit of blueberry and next time, you can offer the full serving size.

How Often Can A Hamster Eat Blueberries?

Here’s the tricky part (well, a little tricky, anyway): Your hamster can have a teeny, tiny bit of fruit once a day, but no more than that. So don’t give your pet a blueberry if you’re planning to give them some other kind of fruit like apple or grape, unless you provide an even tinier amount of each one.

There’s a little more to consider the first time you give your hamster blueberry:

  • If you’ve had your hamster for a while and they’re already accustomed to fruits and vegetables, it’s fine to give them one blueberry per day. When offering other fruit, make sure you give them a tiny blueberry or half a larger one, so they don’t eat too much sugar at once.
  • If you just brought your hamster home and you’re not sure whether they’ve had fresh food in the past, offer a tiny amount of fresh fruit or vegetable once every other day for the first week and gradually increase the amount from there. Remember to watch for diarrhea – it’s a sign that you’re transitioning to fresh food too quickly.

The Correct Diet is Important

While some animals eat pretty much the same thing each and every day, hamsters are omnivores. Their natural diet consists of pretty much whatever they can find including insects, worms, and plenty of different plant material.

Fresh Timothy hay is a very important part of your hamster’s diet. The fiber helps keep their digestive system healthy and the hay makes the ideal material for fun tunneling behavior and cozy nest-making.

Here’s what else to feed your hamster:

  • A daily serving of hamster pellets (check the label to determine how much to offer)
  • All the clean, fresh water your hamster can drink; be sure to rinse and refill their drinking bottle at least once per day
  • Occasional protein treats such as dried mealworms, tiny bits of hard-boiled egg, or even a tiny piece of cooked chicken
  • Occasional bits of birdseed – no more than about a teaspoon per week
  • Tiny bits of fresh fruit and vegetables
  • Chewable treats and hamster toys such as hay cubes, unbleached loofah, untreated softwood, or natural coconut shell, essential for your preventing your hamster’s teeth from becoming overgrown

Since hamsters are hoarders, be sure to feed only as much fresh food as they can eat immediately. Remove any leftovers from your hamster’s habitat to prevent them from adding these to a food cache, where they could spoil, cause mold, and potentially harm your pet’s health.
