What Can A Hamster Eat?

Hamsters can eat various plant-based foods and fruits that humans enjoy eating. An easy choice is feeding them pellet food which has a balanced diet. Most pellets are small and cone-shaped, which is easy for pet hamsters to eat and stuff into their cheek pouches.

An advantage of a pellet diet is that your pet hamster cannot select individual foods from them. In other diets, the pets can pick and eat the sweeter food of the mixture. However, pellets should be mixed with other sweet food choices like fruits and vegetables.

Feeding a hamster is straightforward, especially when serving them store-bought pelleted food. However, to ensure they have a balanced diet, there are things to observe.

How to Feed A Hamster
  • Before providing your pet hamster with its vegetables and fruits, remember to wash them
  • Also, when buying them, ensure they’re organic to clean out pesticides. With their small size, even tiny amounts of pesticide may harm their health
  • You can mix 2 to 3 types of seeds for a healthier diet for your pet. Also, mix them with vegetables for a balanced diet
  • Your mixture can include nuts but remember they should only be served as an occasional treat
  • Also, remove nuts from the shells to minimize the risks of choking
  • Do not serve salt or salted foods because the high sodium can cause them to dehydrate faster

Below are the simple steps you should follow when feeding your pet. 

  1. Place the ideal amount of the food mixtures in the pet’s bowl
  2. Put the food in their feeding location
  3. Add some water to the water bottle or bowl
  • Likewise, provide the food in the evening since these pets are nocturnal and eat at night. 
  • You can make feeding interesting by scattering some of the pellets so that your pet corrects them. Hiding treats is also good as it works better for the pet.
  • Remember to offer your pet fresh or filtered water every day. The water would help in their digestion, especially if your pet ate a lot of dry foods. Also, water helps your pet stay hydrated.
  • Also, remember pets with a condition like pregnancy may require a diet rich in some nutrients. Consult with a veterinarian on these occasions to ensure your pet is feeding on the ideal food.
  • Remove any food not eaten within 12 hours from the cage because they spoil after that time. Pet hamsters spill some food when eating which is why it’s best to clean regularly.

While still on the topic of eating, hamsters require things to chew besides food. Some are for entertainment and fun, while others help avoid teeth malocclusion, which is common in these rodents.

  • Provide your pet hamster with some materials to chew and gnaw on. They can chew cardboard, hay cubes, and seagrass to keep their teeth healthy. Also, some woods like dogwood, elm, hazelnut, Quince, or Yucca, can make a good gnawing material.

How Much Food Should A Hamster Eat?

Hamsters are hoarders and opportunistic feeders, which reflects their instincts. They can hide some foods in the burrows to eat later and beg their owners for more.

  • Pellets and seeds are the main diet and should make up 60% – 70% of the main dish. 
  • Fruits and vegetables can then follow up as additional with at least 20%. 
  • Other treats should range between 5% and 10% of the total diet.
  • Nuts are occasional treats that you can serve in 2-4 pieces per month. 
  • Other treats, especially those high in sugar, like fruits, should be served once per week too.
How Much Food Should A Hamster Eat

Most pelleted foods have instructions on the amount your pet should take. 

  • However, Hamsters should take at least 1/8 or 1/3  of a cup of pelleted food daily.

Veterinarians can help you determine the amount to feed your pet if you’re unsure. They can measure your pet’s weight and determine the amount safe for its consumption. 

  • Animal-based foods should be served after every few days or two times a week. This is to ensure that the pet concentrates on healthier foods like pellets or vegetables and less on treats.
  • While seeds make a good bite-sized snack for the pet, they can be a health hazard if eaten in large amounts. Some are high in fat which can promote conditions like obesity. Avoid overfeeding the pet with a seed diet.

Raw beans

Like potatoes, the high starch in beans can cause diarrhea and, in the worst-case, dehydration.


Peanuts may contain aflatoxins which can negatively impact your pet’s health if ingested.


The stringy nature of celery makes it dangerous for consumption by the pet hamster. It can choke the pet and probably kill it.

Tomato leaves or stems

Tomatoes are acidic, and despite being okay for the pet to eat too much can affect it. Also, if the pet eats the stems and leaves, it can die.


A hamster’s heartbeat is quick and ranges between 10 and 15 beats every second. Caffeine may increase the heartbeat, which can risk heart diseases like cardiac arrest.
