Is It True Do Hamsters Really Fart?

Hamsters bring joy and laughter with their adorable antics, but they are living creatures with bodily functions just like humans. One intriguing aspect of these beloved pets is whether or not they fart. In this article, we’ll delve into the world of hamster flatulence, exploring questions such as how often they pass gas, how loud it is, and whether it has an odor.

Do Hamsters Fart?

The short answer is yes, hamsters do indeed pass gas. Like all living creatures, hamsters are subject to the digestive process, which involves breaking down food and expelling excess gas. During digestion, especially of carbohydrates, gas is produced as a natural byproduct. This gas can accumulate in the stomach or intestines, potentially causing discomfort. Farting is a means of releasing this gas from the body, occurring either through the mouth (burping) or the anus (farting).

It’s important to note that although hamsters are capable of farting, it does not mean they do so frequently or in a way that is readily noticeable. Hamsters are small animals that produce very little gas compared to larger animals or humans. Consequently, their farts are typically rare, quiet, and odorless. You may not even observe or hear your hamster farting unless you pay close attention to their behavior and body language.

Do Hamster Farts Smell?

In general, hamster farts do not have a noticeable odor. The reason for this is the limited amount of gas produced by hamsters, and the composition of their gas primarily consists of odorless components like nitrogen, carbon dioxide, oxygen, and hydrogen. These gases account for approximately 93 percent of the gas in a hamster’s fart.

The remaining 7 percent of the gas in a hamster’s fart comprises methane and hydrogen sulfide, the gases responsible for the pungent and unpleasant smell of human flatulence. However, due to the small quantities of these gases in a hamster’s fart, there is typically no significant smell associated with it.

That being said, there are certain factors that can increase the likelihood of your hamster’s farts being smelly:

  1. Diet: Certain foods can lead to increased gas production or the production of more odorous gas in the digestive system. Foods that are high in protein or fiber can result in more gas production since they are harder to digest and require more bacteria to break them down. Additionally, foods that contain sulfur compounds, such as cruciferous vegetables (like broccoli, cauliflower, and cabbage), eggs, or garlic, can lead to greater odor production due to the increased production of hydrogen sulfide when these foods are digested.
  2. Health: Specific health conditions or diseases can disrupt the digestion or absorption of food in the gut, potentially leading to increased gas or odor production. Bacterial overgrowth, intestinal parasites, food allergies or intolerances, inflammatory bowel disease, or bowel obstruction can all contribute to greater gas or odor production in a hamster.
  3. Stress: Environmental or psychological factors that cause stress or anxiety in your hamster can affect digestion or food absorption in the gut. Factors like loud noises, bright lights, sudden movements, temperature fluctuations, cage cleaning, illness, or injury can induce stress or anxiety in your pet

How to Prevent or Reduce Hamster Farts?

To maintain your hamster’s overall well-being, it’s essential to provide them with optimal care. Here are some tips to achieve that:

  1. Provide a Suitable Cage: Your hamster’s living environment should be spacious, secure, comfortable, and stimulating. Ensure that the cage offers ample space for your hamster to move, exercise, play, hide, and sleep. Additionally, make sure the cage has a solid floor, a secure lid, essential items such as a water bottle, food bowl, nesting box, wheel, toys, and chew items. Place the cage in a quiet, well-ventilated, and temperature-controlled area away from direct sunlight, drafts, or heat sources.
  2. Balanced Diet: Feed your hamster a high-quality commercial hamster mix that includes a variety of seeds, grains, nuts, fruits, and vegetables. You can supplement their diet with hamster-safe fresh fruits and vegetables, like apples, carrots, broccoli, or cucumbers. Avoid feeding them foods that are toxic or harmful to hamsters, such as citrus fruits, onions, garlic, chocolate, or spicy foods.
  3. Handle with Care and Respect: Regular, gentle handling will help your hamster become accustomed to you and build a bond. Always handle your pet carefully, respecting their natural rhythms and preferences. Avoid disturbing them during their rest or sleep, and never force them into uncomfortable or frightening situations.
  4. Monitor Health: Conduct daily checks on your hamster’s health and behavior. Keep an eye out for signs of illness or distress, such as weight loss, loss of appetite, lethargy, diarrhea, sneezing, wheezing, eye or nose discharge, overgrown teeth, lumps, or wounds. If you notice any of these signs or anything else unusual or concerning, consult a veterinarian without delay.
Do Hamsters Fart?


In summary, hamsters can and do fart, although it’s rare for their farts to have a noticeable odor or make noise. Farting is a natural and typical part of the digestive process, allowing the body to expel excess gas. Excessive or smelly farting may be an indication of issues related to your hamster’s diet, health, or environment. The best way to prevent or reduce hamster farts is to offer your pet the utmost care and attention.
