Can Hamsters Have Peanuts?

Yes – But here’s the thing: Hamsters should only have plain peanuts without a lot of salt, added oil, or added flavoring. It’s fine to give your hamster fresh peanuts still in the shell or offer them dry roasted peanuts with no salt.

Are Peanuts Good For Hamsters?

Since peanuts are high in protein and offer plenty of natural plant based fat, they can be a healthy addition to your hamsters diet so long as you offer them in moderation and not too often. Remember that only natural peanuts are good for hamsters. Additives and too much salt can be harmful.

Do Hamsters Like Peanuts?

While there might be a few hamsters that don’t really like the taste of peanuts, most hammies enjoy these crunchy legumes, particularly when they also have the opportunity to extract the peanuts from their shells.

How Much Peanut Can A Hamster Eat?

Peanuts are good for hamsters, but that doesn’t mean they can enjoy them with reckless abandon.

Here’s how much peanut to feed a hamster:

Age Amount
Baby hamster None
Adult hamster 1 whole peanut with shell or 2 to 3 peanuts out of their shell.

Give a hamster a peanut and you’re likely to see one happy hammy nibling away!

Because all new foods need to be offered gradually, start by giving your hamster one peanut kernel outside the shell. Watch for signs of digestive distress over the next 12 hours or so, and so long as everything is alright, go ahead and offer your hamster two peanuts outside the shell next time they’re on your pet’s menu.

The third time you offer your hamster a peanut treat, go ahead and offer them a whole peanut with a shell if you happen to have it on hand. Just make sure that it hasn’t been treated with salt since too much sodium can cause problems for your furry friend.

If you notice any signs of digestive distress, stop giving your hamster peanuts and switch back to a diet of plain hamster food. If problems continue, call your vet for next steps.

How Often Can A Hamster Eat Peanuts?

Your hamster can eat peanuts once or twice per week, but no more often than that . If you’re also offering them peanut butter, count the peanut butter as a peanut treat. All together, these treats should be given twice weekly at a maximum.

You might be tempted to offer your hamster peanuts more often, particularly if you enjoy them yourself, but overdoing it will cause more harm than good, leading to problems including obesity. This might not sound like a big deal and we don’t want to scare you, but being even a little bit overweight is very stressful on a hamster’s body and can shorten your pet’s life significantly.

The Correct Diet Is Important

High-quality hamster pellets are designed to be nutritionally complete. Because of this, it’s perfectly fine to feed your hamster nothing but a diet of food specially formulated for the species. At the same time, it’s likely that your pet will be far happier with a varied, interesting diet that includes special treats like the occasional peanut.

Here’s why we recommend variety:

A hamster’s natural diet is chock-full of different foods including grass, lots of leafy little plants, veggies, perhaps even a few nibbles of fruit here and there, and (this one might surprise you!) animal-based protein including beetles, little amphibians, crickets, and worms.

Be sure to check your hamster’s food package for details about the correct serving size based on their size and lifestage.

Besides a daily serving of ready-made food, here’s what else to feed your hamster:

  • Unlimited amount of fresh hay such as Timothy for nibbling, tunneling, and nesting
  • Unlimited amount of fresh water; rinse and refill your hamster’s drinking bottle daily
  • Birdseed – no more than about a teaspoon per week
  • Little bits of fresh fruit and vegetables once a day or every other day
  • Occasional protein snacks: Dried mealworms and crickets are a very popular option and hamsters really enjoy them
  • Chewable hamster toys and treats designed to keep your hamster’s teeth from becoming overgrown: Coconut shell, hay cubes, unbleached loofah, and untreated softwood are top options

Since hamsters instinctively stash part of their food away for later enjoyment, give them only as much fresh food as they can eat right away. Watch to ensure that they finish up and remove any uneaten extras  to prevent spoilage and mold.

What Are Other Healthy Alternatives To Peanuts In A Hamster’s Diet?

Peanuts are a favorite treat with hamsters everywhere but there are all sorts of other items to keep them occupied on days when crunchy legumes just aren’t in the cards. The good news is that there are tons of veggies to enjoy!

Here’s a short list of some top hamster-approved vegetables to get you started:
