Why Is My Hamster's Coat Ruffled?

A ruffled coat on your hamster will appear to be unkempt, oily, and maybe even wet in some spots. A hamster who is neglecting its normal grooming patterns is usually an indication that something is wrong. Let's talk more about what can be causing this ruffled coat.

Skin Diseases (allergies, skin infections, ringworm, mites)

There are several mites, bacteria, and fungi that can affect your hamster. The most common cause of skin disease in hamsters is caused by the Demodex mite. Skin diseases can cause a decrease in energy resulting in a lack of grooming, causing this ruffled coat appearance. You may also see fur loss, increased scratching or itching, and flaky skin with skin diseases.

Skin conditions are best diagnosed by your veterinarian. Based on their exam, they may recommend performing a skin scraping to diagnose your hamster. 

Wet Tail

Wet tail is also known as proliferative ileitis or regional enteritis. This is a medical condition that involves your hamster having diarrhea and diarrhea-related symptoms. The wetness around the tail is caused by diarrhea, but your hamster may also be experiencing a lack of appetite, energy, and a ruffled coat appearance. Wet tail can be caused by changes in diet, stress, and bacterial infections. This condition can be fatal due to the dehydration your hamster experiences from long bouts of diarrhea.

Respiratory Infection

A sudden change of temperature or cedar bedding can be enough to cause a respiratory infection in your hamster. These infections can lead to a more serious condition, like pneumonia. Symptoms of a respiratory infection include wheezing, decreased energy and appetite, discharge from eyes or nose, and a ruffled coat.

This Caring Pets Resource Guide states, "The best way to prevent a hamster from getting sick from a respiratory problem is to keep living conditions clean, feeding a well-balanced diet, allowing frequent exercise, and keeping your hamster away from cold drafts." 

Other Disease Processes

Many illnesses or diseases will cause stress in your hamster. This stress, alongside other symptoms like lack of energy, will cause your hamster to neglect its care and grooming patterns. Other diseases or health conditions that can leave your hamster with a ruffled coat include:

  • Abbesses
  • Kidney Disease
  • Dental Disease
  • Fractured Bones
  • Cancer and Tumors

What Does It Mean When Your Hamster's Fur Looks Wet?

Your hamster's fur can appear wet for many reasons, some more serious than others. We talked about wet tail being a serious condition. If your hamster has a wet tail, or the areas around the tail are wet, they may be having diarrhea.  When a hamster has these symptoms, it is best to get them checked out by your veterinarian, as this can be a serious condition.

If your hamster is wet behind the ears or along its body, this can result from grooming or normal oils being secreted. These areas being wet bring up less concern and, in most cases, is entirely normal.

Hamsters with dental disease or other oral issues may have wet hair around the mouth and chin. Some issues include infections, overgrown teeth, and ulcers in the mouth. These issues can cause problems with eating and swallowing and should be looked at by your veterinarian. 

What Does It Mean If Your Hamster Is Losing Fur?

Did you know it is normal for hamsters to lose fur with old age? Their fur may get thinner and seemingly more greasy with time, and this is normal. Fur loss can also be a result of skin conditions like mites or nutritional deficiencies as well. Diets low in vitamin B and proteins are part of these deficiencies.

Excessive friction can be a culprit for your hamster losing fur. Rubbing against the cage bars or a hamster obsessed with burrowing can lead to this loss of fur. If you are unsure what is causing bald spots to appear on your hamster, getting a diagnosis from your veterinarian is the best next step.

What Can I Feed My Sick Hamster?

Typically, sick hamsters will lose their appetite. Due to their size, a small amount of time without eating can create a large impact. If your hamster starts to lose interest in food, you can try feeding foods that are high in calories and easy to eat. Some foods to consider include small amounts of cooked egg, baby food, and cooked chicken. Keep in mind when feeding cooked food to your hamster to leave out any additional spices or seasonings.
