What It Might Mean If Your Pet Hamster Has Matted Fur (And When To Worry)

Most hamsters are pros at keeping their fur looking great through self-grooming. You'll often see them happily rubbing their hands over their faces and bodies to clean their coats. Certain breeds, such as teddy bear hamsters, benefit from additional weekly brushing to stop mats from forming in their longer coats. Some hamsters also enjoy dust baths.

However, if your hamster struggles to groom themself or you notice matted fur, it could be a cause for concern. Signs of illness, such as dull eyes, weight loss, diarrhea, or goop in the eyes or nose, in conjunction with matted fur mean it's time to visit the vet, per Animal Humane Society. One source of fur matting can be wet tail,  a watery diarrhea potentially caused by factors like bacteria, stress, or poor diet. As it can result in serious dehydration, it's best to seek treatment from a vet ASAP.

Parasites, both internal and external, can lead to matted fur through excessive scratching or diarrhea. Treating parasites like fleas on your hamster can prevent further issues. In addition, infections of the eyes and ears can lead to discharge that causes matted hair around the face. Other causes, such as cuts, scrapes, and skin infections, may produce matting around the affected skin. Luckily, you can do a lot to help prevent these problems.

Good nutrition, routine cleaning of your hamster's environment, and regular care can help reduce some of the causes of matted fur. Make sure your pet enjoys a balanced diet of hamster-safe foods, including grains, fresh fruit and vegetables, and the occasional treat. It's also a good idea to remove any leftover food or soiled water daily.

The bedding in your hamster's cage should also be replaced weekly during cage cleanings. Using absorbent materials like Carefresh Paper Bedding or safe wood shavings will help keep the environment more sanitary. Avoid bedding made from pine or cedar to reduce respiratory issues. Clean food, water dishes, and accessories at least once a week.

Keeping your hamster well groomed can also alert you to any parasites and matting before they become serious. Long-haired hamsters can be brushed weekly with a small pet brush or fine-toothed comb to remove dirt and debris. Meanwhile, short-haired hamsters may enjoy dust baths to help remove excess oil from their fur. If you notice any changes in your hamster's behavior or symptoms of illness, seek professional help.

Always consult your veterinarian before making changes to your pet's diet, exercise, or care. To find an accredited veterinarian in your area, you can search the American Animal Hospital Association's online database.
