Why is my hamster not eating food

Although hamsters generally have a big appetite and are usually quite flexible with regards to their diet, you might occasionally notice that your hamster won’t eat. If your hamster is not eating, the first thing we recommend doing is taking a look at their diet. Is your hamster’s diet monotonous?

There is a large possibility that your hamster is bored with his/her diet. Hamsters need and enjoy a varied diet which meets their full nutritional requirements. While you can buy a feed at your local pet store, we recommend also offering your hamster natural and fresh foods. Some fresh and natural foods hamster can eat include:

  • Bananas
  • Cucumber
  • Carrots
  • Brocolli

Hamster not eating: heat

Almost all animals, especially mammals, reduce their food intake during hotter days (summer). If your hamster is not eating food because it’s very hot, don’t force it to eat. Instead, we recommend offering your hamster fresh foods which are rich in water in order to keep it hydrated. does not want to eat your food because it is very hot, you should not force it but you can offer fresh foods rich in water to keep it well hydrated. Fruits that hamsters can eat include:

  • Watermelon: Many people wonder, ‘‘Can hamsters eat watermelon?’’ In small doses, Yes. If you give your hamster TOO much watermelon, it can cause vomiting or diarrhea.
  • Apples.
  • Kiwi fruit.
  • Peaches.

With the arrival of summer, you should also be vigilant and avoid heat stroke in hamsters. Heat stroke in hamsters can be fatal! In addition to controlling the temperature of your hamster’s environment, it is essential that you ALWAYS provide your hamster with clean fresh water. Remember to always place your hamster’s cage in a cool environment where it doesn’t receive direct sunlight. For more, we recommend reading our article where we tell you everything you need to know about preparing a hamster’s cage.

My hamster won’t eat: stress

As we’ve already mentioned, hamsters are sensitive animals that can easily be affected by environmental and routine changes. If your hamster’s cage is not filled with physical and mental enrichment to play and exercise with, it can result in hamster stress.

Stress in hamster symptoms include:

  • Hyperactivity, nervousness or anxiety.
  • An increase in unusual habits, such as biting its cage.
  • Changes in appetite: When feeling nervous or hyperactive, some hamsters will eat more while others eat less or nothing at all.
  • Hamster behavior problems: by failing to release stress positively, many hamsters begin to act in an obsessive and repetitive manner, known commonly as stereotyping in hamsters.
  • Additional behavioral problems: aggressiveness is one of the most common symptoms of stress in hamsters. Aggression in hamster can also be associated with certain diseases. Therefore, if your hamster tries to bite you, we recommend consulting your veterinarian as soon as possible.

On the other hand, hamsters can become very sad and depressed when they don’t receive accurate care. A sad or depressed hamster may:

  • Lose interest in food.
  • Reduce daily physical activity.
  • Isolate itself.

Is your new hamster not eating? How about your old hamster not eating? In addition to the above mentioned causes, hamsters may also lose appetite due to:

For more, take a look at our article where we discuss how to care for a hamster’s teeth.

Therefore, remember to clean your hamster’s cage regularly, removing waste and stool. We also recommend cleaning out and sanitizing your hamster’s cage with warm water and soap once a week.
  • Constipation: A constipated hamster may refuse to eat or eat very little. Constipation in hamsters is often caused by a diet poor in fiber, insufficient water consumption or hair ingestion. To help, include fiber-rich fruits and vegetables into your hamster’s diet, such as plums, pears, lettuce and spinach.
