Why Does My Throw Up Food : Causes and Solutions 

When you notice chewed food inside your hammies’ cage, you might assume it’s been throwing up and having issues with digestion. The fun fact is that hamsters don’t vomit. They only throw up or spit out the food stored in their cheek pouches. 

But why do hamsters throw up food? When the hamster suspects danger or becomes scared, it spits out food to run faster. This also happens when the hamster gets stressed or anxious. Lack of variation in the diet and getting introduced to a new environment are also two key reasons why your hamster is throwing up.

Let’s get into the details of why hamsters throw up and what to do if your hamster spits out food or refuses to eat at all. We will also discuss why hamsters cannot vomit and some related hazards.

Hamsters Throwing Up Food: Causes, Symptoms, and Solutions 

Your hamster has two large pockets on each side of its mouth to store food. Typically, it saves the food items to eat later in a more comfortable position. When it throws up, you only see the chewed food mixed with saliva. Remember, once the food enters the digestive tract, there’s no coming back.

Here are the reasons why your hamster might be spitting out chewed food and some possible solutions.

Cause 1: The Hamster Was Attacked 

Throwing up chewed food is a simple defense response in hamsters. When a hamster is attacked, it quickly spits out the food it was stored inside its cheek pouches. Escaping becomes a bit tough when your hamster’s mouth is full. So, it releases the extra weight to get ready for running away from the location.

If you have multiple pets at your house, one of them might have attacked the hamster. Little kids might also be held responsible for unintentional attacks. 

What are the Symptoms?

If your hamster was attacked, you’d notice the following symptoms:

❖   Inappetence or anorexia 

❖   Frequent breathing 

❖   Restless behavior 

❖   Bleeding

❖   Loud crying

❖   Limping

❖   Labored breathing

What’s the Solution?

Keep your hamster in a separate cage protected from other pets. Even if you take it out to play with it, be careful about not leaving it alone, especially if you have kids at home. In short, make sure no one can attack your little pet, as it will not only make the hamster throw up food but also cause injuries.

Cause 2: It Suspects Danger 

Even if the hamster wasn’t attacked or injured, it might spit out food upon suspecting any type of danger. This can happen when someone approaches the little soul aggressively or makes a loud sound. If the hamster gets scared for some reason, it might throw up food and refuse to eat or drink.

What are the Symptoms?

When a hamster is scared, it might display the following signs:

❖   Hiding

❖   Biting and scratching 

❖   Acting skittish 

❖   Running restlessly

What’s the Solution?

Avoid doing things that might come across as aggressive. 

❖   Simply spread your palms towards it to get familiar with it. 

❖   Don’t hover your hands, making it look like you’re grabbing the hamster. 

❖   Let the hamster slowly get introduced to new members of your family. 

❖   Gently talk to it and avoid making loud sounds.

Cause 3: Your Pet Is Stressed or Nervous 

A stressed hamster can consistently spit out food from their pouches. Just like humans, hamsters can also become nervous easily for a bunch of environmental factors. Rough handling, lack of proper hygiene, sudden movements, poor diet, etc., are some reasons why your little friend might be stressed.

Besides, if it’s affected by bacteria, viruses, or other parasite-related infections, it will show signs of stress and nervousness. Lack of physical activity can also make your pet nervous. 

What are the Symptoms?

If your hamster becomes stressed or nervous, it will try to release the stress by being overly active. Here are the signs a stressed hamster will display:

❖   Excessive salivation 

❖   Hyperactivity

❖   Making strange noises 

❖   Hair loss 

❖   Aggressiveness

❖   Compulsive behavior

What’s the Solution?

Be very gentle while handling your hamster. Clean its cage regularly and ensure a healthy diet. You must arrange some toys like wheels and balls to keep the hamster active.

Don’t take it too high, and avoid moving it roughly when it’s resting. Finally, check if the hamster has any type of pathological disease and contact your vet if necessary.

Cause 4: Moving To A New Environment 

Some hamsters are not so good at socialization. So, if you’re trying to play with it right after bringing it home, you’ll make it nervous and scared. Even a simple touch can trigger the hamster and make it fearful for days.

As a result, the hamster will reject food and throw up when you try to touch it. This might also happen when you move your pet to a new cage or new house.

What are the Symptoms?

In this case, the hamster will show unusual behaviors such as:

❖   Climbing the cage 

❖   Gnawing incessantly 

❖   Turning on its back

❖   Biting things around its cage 

❖   Tries to run away

What’s the Solution?

When you bring a new hamster at home, give it a few days to settle down. Avoid touching it at all during this period. First, make it familiar with your smell by letting it sniff your hands. After that, gently hold and lift it on your palms.

Talk to it and pet it while feeding it. Once the hamster is comfortable with petting, you can start holding it and moving around. This way, your hamster will start socializing and get used to the environment.

Cause 5: Lack of Food Variation 

Your hamster can easily get bored of eating the same food every day. Even if it’s a healthy and nutritious diet, you need to bring variation to its daily meals. Otherwise, the hamster might refuse to eat or throw up after taking a bite.

What are the Symptoms?

Apart from throwing up, the hamster will refuse to eat if it doesn’t like the food.

What’s the Solution?

Mix different types of fruit and veggies to make the meal tasty, healthy, and appealing. Treat your hammer with dry foods like oats, seeds, and nuts so that it doesn’t get bored of eating only one type of food every day.

Why Don’t Hamsters Vomit?

A group of neuroscientists has found that hamsters lack gag or vomit response due to their anatomical structure. Features like a less muscular diaphragm, thin muscles under their lungs, a long esophagus, and a one-way digestive system are the reasons why hamsters are unable to vomit.

Besides, hamsters lack the brain neurons that produce the vomiting response against overeating. When hamsters throw up, they are only spitting out the food stored in their cheek pouches. These pockets can expand up to 20% of their original size. On some rare occasions, the hamster might gag or choke on food.

As hamsters don’t vomit, you must ensure your hamster takes measured food according to its age and body weight.
